'''Interstate&nbsp;895''' ('''I-895''') is an [[auxiliary Interstate Highway]] in the [[US state]] of [[Maryland]]. Known as the '''Harbor Tunnel Thruway''', the highway runs {{convert|11.44|mi|km}} between one junction with [[Interstate 95 in Maryland|I-95]] in [[Elkridge, Maryland|Elkridge]] and another interchange with I-95 on the east side of [[Baltimore]]. I-895 is a [[toll road]] that crosses the [[Patapsco River]] estuary via the [[Baltimore Harbor Tunnel]], connecting [[U.S. Route 1 in Maryland|U.S. Route&nbsp;1]] (US&nbsp;1), [[Interstate 695 (Maryland)|I-695]], and the [[Baltimore&ndash;Washington Parkway]] (B–W Parkway) in the southwestern suburbs of Baltimore with [[U.S. Route 40 in Maryland|US&nbsp;40]] on the east side of Baltimore. In conjunction with a pair of spurs, [[unsigned highway|unsigned]] [[#Auxiliary routes|I-895A and I-895B]], I-895 provides access to the tunnel from [[Interstate 97|I-97]] and [[Maryland Route 2]] (MD&nbsp;2) in [[Glen Burnie, Maryland|Glen Burnie]]. The highway is designed for through traffic by having partial interchanges that require vehicles from almost all starting points (with the two northernmost exits being exceptions) to pass through the tunnel and the tunnel toll plaza, where a $1.40-$6.00 toll is charged to passenger vehicles, before exiting the facility.<ref>{{cite web | url=https://mdta.maryland.gov/TollRatesTables | title=TollRatesTables &#124; MDTA }}</ref>

The idea of a crossing of the Patapsco River south of [[Downtown Baltimore]] had been studied since the 1930s. In the early 1950s, the [[Maryland State Roads Commission]] (SRC) chose to construct a four-lane tunnel between the [[Canton, Baltimore|Canton]] and [[Fairfield, Baltimore|Fairfield]] neighborhoods of Baltimore and approach highways to connect the tunnel with major highways to [[Washington, D.C.]]; [[Annapolis, Maryland|Annapolis]]; [[Richmond, Virginia]]; and [[Philadelphia, Pennsylvania]]. The tunnel and approach highways were constructed beginning in 1955 and opened in November 1957, opening a bottleneck for Baltimore through traffic, which formerly had to navigate the city streets. The Harbor Tunnel Thruway was connected with the [[John F. Kennedy Memorial Highway (Maryland)|John F. Kennedy Memorial Highway]] in the early 1960s and the portion of I-95 south to Washington DC in the early 1970s. With these connections, I-895 was burdened with most of the through traffic passing through Baltimore. The congestion was not resolved until [[Interstate 95 in Baltimore, Maryland|I-95 through Baltimore]] was completed when the eight-lane [[Fort McHenry Tunnel]] opened in November 1985. The transfer of most traffic to the new tunnel allowed the Baltimore Harbor Tunnel to be partially shut down for extensive maintenance in the late 1980s.

In 2024, I-895 was designated a main detour route for through non-hazmat traffic in the wake of the [[Francis Scott Key Bridge collapse]].

==Route description==
I-895 is maintained by the [[Maryland Transportation Authority]] (MDTA) and, like all Interstate Highways, is a part of the [[National Highway System (United States)|National Highway System]] for its entire length.<ref name="Maryland HLR"/><ref name="National Highway System"/>

===Western approach===
[[File:2016-05-11 07 15 55 View south along Interstate 895 (Baltimore Harbor Tunnel Thruway) as it crosses over the CSX's Curtis Bay Branch rail line in Baltimore City, Maryland.jpg|thumb|left|K-Truss Bridge over railroad tracks southwest of the tunnel]]
I-895 begins at exit&nbsp;46 of I-95 in Elkridge with single-lane flyover ramps from northbound I-95 to I-895 and from I-895 to southbound I-95. The highway, which has a speed limit of {{convert|65|mph|km/h|abbr=on}}, expands to four lanes on a viaduct over local roads and [[CSX Transportation]]'s [[Capital Subdivision]] railroad line and [[MARC Train]]'s [[Camden Line]]. I-895 crosses the Patapsco River (the [[Howard County, Maryland|Howard]]&ndash;[[Baltimore County, Maryland|Baltimore]] county line) and US&nbsp;1 (Washington Boulevard), then receives the exit&nbsp;1 flyover ramps from northbound US&nbsp;1 and to southbound US&nbsp;1 before passing under [[Interstate 195 (Maryland)|I-195]] with no access. I-895 continues east parallel to the Patapsco River. The highway passes along the southern edge of [[Halethorpe, Maryland|Halethorpe]], where it crosses [[Amtrak]]'s [[Northeast Corridor]] railroad line and MARC Train's [[Penn Line]] along with Herbert Run.<ref name="Maryland HLR"/><ref name="Maryland Grid Map"/>

I-895 meets I-695 (Baltimore Beltway) at exit&nbsp;3, which includes a loop ramp from eastbound I-695 and a ramp to westbound I-695. The highway crosses Hammonds Ferry Road in [[Baltimore Highlands, Maryland|Baltimore Highlands]] before exit 4 with MD&nbsp;295 (B–W Parkway), which includes a loop ramp to southbound MD&nbsp;295 and a ramp from northbound MD&nbsp;295. The speed limit drops to {{convert|55|mph|km/h|abbr=on}}, then the highway crosses [[Maryland Route 648|MD&nbsp;648]] (Annapolis Road) and curves northeast across marshland, the main line of the [[Maryland Transit Administration]] (MTA)'s [[Baltimore Light RailLink]], and the Patapsco River into [[Anne Arundel County, Maryland|Anne Arundel County]]. East of the river, I-895 receives flyover ramps from the thruway's southern approach, unsigned I-895B, at exit&nbsp;6 in [[Brooklyn Park, Maryland|Brooklyn Park]].<ref name="Maryland HLR"/><ref name="Maryland Grid Map"/>

The highway enters the city of Baltimore and curves to the east over Patapsco Avenue before exit&nbsp;7 with MD&nbsp;2 (Potee Street), which includes a loop ramp to southbound MD&nbsp;2 and a ramp from the intersection of MD&nbsp;2 and [[Maryland Route 173|MD&nbsp;173]] (Patapsco Avenue). I-895 parallels CSX Transportation's Curtis Bay Branch as the highway passes along the northern edge of the [[Brooklyn, Baltimore|Brooklyn]] neighborhood. The highway crosses the Curtis Bay Branch on a steel [[K-truss]] bridge ahead of exits&nbsp;8A and 8B. Exit&nbsp;8A includes a loop ramp to and a flyover ramp from Shell Road, which heads toward the [[Curtis Bay, Baltimore|Curtis Bay]] neighborhood. Exit&nbsp;8B includes ramps from eastbound Frankfurst Avenue and to westbound Frankfurst Avenue; that street leads to Hanover Street and [[Downtown Baltimore]]. I-895 passes through the 14-booth toll plaza for the tunnel; immediately to the east of the toll plaza is exit&nbsp;9, a half [[diamond interchange]] with Childs Street for traffic to and from the toll plaza. The speed limit decreases to {{convert|50|mph|km/h|abbr=on}} as the highway curves to the northeast through the Fairfield unit of the [[Port of Baltimore]] and descends into the Baltimore Harbor Tunnel.<ref name="Maryland HLR 2005"/><ref name="Maryland Grid Map"/>

===Northern approach===
[[File:2016-08-12 15 49 22 View north along Interstate 895 (Baltimore Harbor Tunnel) in Baltimore City, Maryland.jpg|alt=|thumb|Baltimore Harbor Tunnel]]
I-895 surfaces from the tunnel adjacent to the toll plaza for the [[Fort McHenry Tunnel]] within the Canton neighborhood. The highway passes over several rail lines of the [[Canton Railroad]] and several streets as it curves to the north. The exit&nbsp;10 ramp to Holabird Avenue diverges from I-895 immediately before the highway passes under I-95 with no access. I-895 returns to ground level and the highway crosses Ponca and Boston streets; the speed limit increases to {{convert|55|mph|km/h|abbr=on}} ahead of exits&nbsp;11A and 11B, which serve Boston and O'Donnell streets, respectively (with ramps to/from eastbound Boston Street and loop ramps to/from westbound O'Donnell Street). The highway crosses a rail line before passing through the [[Greektown, Baltimore|Greektown]] neighborhood in a cut. I-895 passes under [[Maryland Route 150|MD&nbsp;150]] (Eastern Avenue) ahead of exit&nbsp;12, a four-ramp [[partial cloverleaf interchange]] with Lombard Street just to the west of [[Johns Hopkins Bayview Medical Center]] that has ramps in both directions of the Interstate, and is the only interchange to be built out that way.<ref name="Maryland HLR 2005"/><ref name="Maryland Grid Map"/>

The highway veers northeast and crosses both Amtrak's Northeast Corridor and CSX Transportation's [[Philadelphia Subdivision]] railroad lines before exit&nbsp;13 with US&nbsp;40 (Pulaski Highway) and [[Maryland Route 151|MD&nbsp;151]] (Erdman Avenue); the entrance ramp extends from the US&nbsp;40&ndash;MD&nbsp;151 partial cloverleaf interchange immediately to the north and west.<ref name="Maryland HLR 2005"/> After crossing Herring Run, I-895 meets Moravia Road at exit&nbsp;14, a five-ramp partial cloverleaf interchange that lacks an exit from northbound I-895, which is accessed via exit&nbsp;13 and a loop ramp to the northwest. This interchange complements exit&nbsp;60 off I-95, where the eastern terminus of Moravia Road meets the planned western terminus of the [[Windlass Freeway]].<ref name="Maryland HLR 2005"/><ref name="Maryland Grid Map"/> A branch of the I-95 Express Toll Lanes begin within the interchange with Moravia Road, there are ramps from northbound I-895 to the northbound toll lanes, and from the southbound toll lanes to southbound I-895. The highway crosses Moores Run before reaching its northern terminus at exit&nbsp;62 of I-95 (John F. Kennedy Memorial Highway), a pair of flyover ramps from I-895 to northbound I-95 and from southbound I-95 to I-895 on the boundary between the city of Baltimore and the Baltimore County community of Rosedale.<ref name="Maryland HLR"/><ref name="Maryland HLR 2005"/><ref name="Maryland Grid Map"/>

==History==

===Planning and construction===
[[File:2019-07-17 10 53 24 View north along Interstate 895 (Baltimore Harbor Tunnel Thruway) from the overpass for Fleet Street in Baltimore City, Maryland.jpg|thumb|right|I-895 northbound passing through the Greektown section of Baltimore]]
In 1938, the SRC commissioned an engineering study, Maryland's Primary Bridge Program, to examine feasibility of major bridges across significant transportation barriers, including a bridge crossing the Patapsco River southeast of the [[Inner Harbor]].<ref name="1938 src report"/> Another study in 1944 examined the idea of a bridge with limited-access approach roads running from US&nbsp;1 in Elkridge to the Patapsco River crossing and from the bridge to US&nbsp;40 near Erdman Avenue in east Baltimore.<ref name="1944 src report"/> The financial resources for the project were established in 1947 when the [[Maryland General Assembly]] passed an act allowing for the pooling of revenue bonds and toll receipts between the state's toll facilities&mdash;the existing [[Governor Harry W. Nice Memorial Bridge|Potomac River]] and [[Thomas J. Hatem Memorial Bridge|Susquehanna River]] bridges, and the upcoming [[Chesapeake Bay Bridge]]&mdash;to finance the construction of the Patapsco River Crossing.<ref name="1950 src report"/>  Finally, a 1953 study examined three different routes&mdash;Canton–Fairfield, Canton–[[Fort McHenry]], and a Canton–Fort McHenry–Fairfield dual crossing option&mdash;and whether the crossing should be a bridge or tunnel.<ref name="1954 src report"/>

In 1954, the SRC decided to construct a tunnel between Canton and Fairfield, with three approach highways: a west approach from US&nbsp;1 in Elkridge, a south approach from MD&nbsp;2 in Glen Burnie to connect with the west approach in Brooklyn Park, and a north approach from US&nbsp;40 and Erdman Avenue in east Baltimore. The approach highways were to be limited-access with directional, partial interchanges so that only traffic intending to use the tunnel would use the approach roads. Any vehicles entering an approach road would not be able to exit until having passed through the tunnel and the tunnel toll facility.<ref name="1954 src report"/>

Shortly after work began on the Patapsco Tunnel Project on April 7, 1955, several changes were made to the plans for the approach highways. The northern terminus at US&nbsp;40 was altered to allow an extension from US&nbsp;40 to the southern end of the future Northeastern Expressway (now the John F. Kennedy Memorial Highway). As a result, additional connections with US&nbsp;40 were planned for the area around present day exit&nbsp;14. In addition, the south approach was to have a tie-in to the Glen Burnie Bypass (now I-97) then under construction.<ref name="1956 src report"/> The tunnel and approach highways were completed and opened November 29, 1957, as the Baltimore Harbor Tunnel and the Harbor Tunnel Thruway, respectively.<ref name="1958 src report"/> The opening of the tunnel and approach roads removed a significant amount of traffic from the streets of Baltimore and eliminated 51 traffic lights from the route of motorists passing through the city.<ref name="Harbor Tunnel Fact Sheet"/><ref name="50th Anniversary"/>

===Improvements and relief===
The Harbor Tunnel Thruway was extended north to the city limits of Baltimore to seamlessly connect with the Northeastern Expressway when that highway opened northeast to the Baltimore Beltway in 1961.<ref name="Transportation Milestones"/><ref name="1962 map"/> In 1969, Moravia Road was extended east to US&nbsp;40 using the connector between US&nbsp;40 and the thruway and several ramps were added to that road's interchanges with US&nbsp;40 and the thruway.<ref name="1970 map"/> In addition, flyover ramps were constructed at the city limits for I-95 to diverge from the John F. Kennedy Memorial Highway onto its own path through east Baltimore in 1970.<ref name="1971 map"/> The Harbor Tunnel Thruway was extended at its south end in 1973 to connect with I-95 shortly after that Interstate was completed between the [[Capital Beltway]] and the Baltimore Beltway in 1971.<ref name="Transportation Milestones"/><ref name="1974 map"/>

Since I-95 had not yet been completed through Baltimore, the Harbor Tunnel Thruway, which was designated I-895 in 1979, was the main route for traffic passing through Baltimore.<ref name="1979 map"/> As a result, the highway was very congested, and travel through Baltimore had once again become a bottleneck. Relief came with the completion of the eight-lane Fort McHenry Tunnel on I-95 on November 23, 1985.<ref name="Ocala Star-Banner Tunnel Opens"/> With most traffic diverted to the new tunnel, major reconstruction work began on the Baltimore Harbor Tunnel. Traffic was reduced to one lane in each direction through the tunnel as each of the two tubes was renovated between 1987 and 1989.<ref name="Harbor Tunnel Face-Lift"/> More recent changes include the elimination of the entrance ramp from Ponca Street at exit&nbsp;10, the expansion of exit&nbsp;12 to a full interchange (the only full interchange along the route other than its termini at I-95) to provide access to Johns Hopkins Bayview Medical Center in both directions (thus shortening the toll portion of I-895), and the reconstruction of the northern interchange with I-95 in 2009 so I-895 enters and exits I-95 on the right side of the roadway; previously, I-95 exited itself southbound by forcing traffic to weave to the right and access a flyover ramp, and northbound I-895 merged with I-95 from the left.<ref name="Baltimore Sun I-95 North Interchange"/>

The Canton Viaduct, a {{convert|3400|ft|m|adj=on}} elevated structure carrying I-895 over a railroad yard, Ponca Street and the ramps connecting I-95 to Keith Avenue, was replaced in the late 2010s and early 2020s. The project was announced in 2014.<ref name="Rector 2014">{{cite web |last=Rector |first=Kevin |date=November 13, 2014 |title=Five-year construction project on I-895 north of Harbor Tunnel to begin 2016 |url=https://www.baltimoresun.com/maryland/bs-md-895-construction-20141113-story.html |access-date=November 6, 2022 |website=Baltimore Sun}}</ref><ref name="CBS Baltimore 2014">{{cite web |date=November 16, 2014 |title=895 Bridge Construction About To Snarl Traffic For Years |url=https://www.cbsnews.com/baltimore/news/895-bridge-construction-about-to-snarl-traffic-for-years/ |access-date=November 6, 2022 |website=CBS Baltimore}}</ref> The viaduct, next to the toll plaza for the Fort McHenry Tunnel, was one of the oldest Interstate bridges in Maryland. Similar to what was done in the late 1980s rehabilitation of the tunnel, one side of the viaduct was closed while the other operated with one lane in each direction. Construction started in 2018 and was expected to be completed in 2021.<ref>{{cite news |last=Campbell |first=Colin |date=November 9, 2018 |title=Construction on I-895 in Baltimore to cause major traffic problems for the next three years |work=The Baltimore Sun |url=https://www.baltimoresun.com/maryland/baltimore-city/bs-md-895-tunnel-bridge-delays-20181108-story.html |access-date=August 7, 2019}}</ref>

===Tolls and exit numbers===
The original toll for the Harbor Tunnel Thruway was $0.40 (equivalent to ${{Formatprice|{{inflation|US|0.40|1957|r=2}}}} in {{Inflation/year|index=US}}{{Inflation/fn|index=US}}) for passenger vehicles and $0.85 (equivalent to ${{Formatprice|{{inflation|US|0.85|1957|r=2}}}} in {{Inflation/year|index=US}}{{Inflation/fn|index=US}}) for trucks.<ref name="Baltimore Bottleneck Unplugged"/> By 1985, the toll had risen to $1.00 (equivalent to ${{Formatprice|{{inflation|US|1.00|1985|r=2}}}} in {{Inflation/year|index=US}}{{Inflation/fn|index=US}}).<ref name="Ocala Star-Banner Tunnel Opens"/> [[Electronic toll collection]] began at the toll plaza in 1999 for M-TAG customers; the M-TAG system was absorbed by [[E-ZPass]] in 2001.<ref name="Baltimore Sun Electronic Toll"/> The MDTA increased the toll for passenger vehicles to $2.00 (equivalent to ${{Formatprice|{{inflation|US|2.00|2003|r=2}}}} in {{Inflation/year|index=US}}{{Inflation/fn|index=US}}) in 2003.<ref name="MdTA Toll Rates"/><ref name="Baltimore Sun Higher Tolls"/> In May 2011, the agency announced the toll for the Harbor Tunnel Thruway and the two other harbor crossings would increase to $3.00 (equivalent to ${{Formatprice|{{inflation|US|3.00|2011|r=2}}}} in {{Inflation/year|index=US}}{{Inflation/fn|index=US}}) on October 1, 2011, and to $4.00 (equivalent to ${{Formatprice|{{inflation|US|4.00|2013|r=2}}}} in {{Inflation/year|index=US}}{{Inflation/fn|index=US}}) on July 1, 2013.<ref name="Baltimore Sun Higher Tolls"/>

The Harbor Tunnel Thruway has had three different exit number systems throughout its existence. The first numbering scheme was in place by 1963. The northbound exits were numbered between 1 (Holabird Avenue) and 5 (US&nbsp;40), while the southbound exits were numbered 1 (Hanover Street) to 7 (US&nbsp;1).<ref name="1963 map"/> The second numbering scheme, which did not change the interchange numbers on the northern approach to the tunnel, was introduced in 1971. The exits on the western approach were renumbered 11 (Hanover Street) to 17 (US&nbsp;1).<ref name="1971 map"/> Under both schemes, the Childs Street exit did not have a number and the Moravia Road interchange was numbered as exit&nbsp;1 of the John F. Kennedy Memorial Highway.<ref name="1970 map"/> The third and present numbering scheme was enacted in 1991.<ref name="1991 map"/>

==Auxiliary routes==
I-895 has two unsigned auxiliary routes, I-895A and I-895B. Both highways are portions of the southern approach to the Baltimore Harbor Tunnel that connects with the mainline of the Harbor Tunnel Thruway in [[Brooklyn Park, Maryland|Brooklyn Park]]. Both spurs are maintained by MdTA. I-895A and the portion of I-895B north of I-895A are part of the main National Highway System. The segment of I-895B between MD&nbsp;2 and I-895A is a National Highway System principal arterial.<ref name="Maryland HLR"/><ref name="National Highway System"/>

===I-895A===
I-895A is the designation for the {{convert|0.71|mi|km|adj=on}} connector between the northern end of I-97 just north of I-695 (Baltimore Beltway) and I-895B within [[Glen Burnie, Maryland|Glen Burnie]].<ref name="Maryland HLR"/><ref name="Maryland Grid Map"/> The highway was constructed in 1957 to connect the northern end of the Glen Burnie Bypass with the Harbor Tunnel Thruway.<ref name="1956 src report"/> In conjunction with the reconstruction of I-97's interchange with I-695, in which the loop ramp from I-97 north to I-695 west was replaced with a flyover joining I-695 on the left, a loop ramp was added on I-895A in 1995 to allow access to the right side of I-695 west for traffic exiting at MD&nbsp;648 (Baltimore–Annapolis Boulevard).<ref name="Baltimore Sun Ramp 648"/>
