'''U.S. Route&nbsp;206''' ('''US&nbsp;206''') is a {{convert|130.23|mi|km|adj=mid|-long}} north–south [[United States Numbered Highway]] primarily in the state of [[New Jersey]].{{Efn|The northernmost half mile (800 m) of its length is in Pennsylvania; the [[Milford–Montague Toll Bridge]] carries it over the [[Delaware River]] into New Jersey, where it is for the remainder of the route.}} Its southern terminus is at an intersection with [[U.S. Route 30 in New Jersey|US&nbsp;30]] and [[New Jersey Route 54|Route&nbsp;54]] in [[Hammonton, New Jersey|Hammonton]], while its northern terminus is at an intersection with [[U.S. Route 209|US&nbsp;209]] near [[Milford, Pennsylvania]].{{Efn|Some sources and signs show an [[concurrency (road)|overlap]] with US&nbsp;209 to end at its parent route [[U.S. Route 6 in Pennsylvania|US&nbsp;6]], about one mile to the north.}} For much of its length, US&nbsp;206 is a rural two-lane undivided road that passes through the [[Pine Barrens (New Jersey)|Pine Barrens]], agricultural areas, and the [[Appalachian Mountains]] of northwestern New Jersey, with some urban and suburban areas. The route connects several cities and towns, including [[Bordentown, New Jersey|Bordentown]], [[Trenton, New Jersey|Trenton]], [[Princeton, New Jersey|Princeton]], [[Somerville, New Jersey|Somerville]], [[Roxbury, New Jersey|Roxbury]], [[Netcong, New Jersey|Netcong]], and [[Newton, New Jersey|Newton]]. The road is known as the '''Disabled American Veterans Highway''' for much of its length.

What is now US&nbsp;206 in New Jersey was designated as part of several state routes prior to 1927, including [[Pre-1927 Route 2 (New Jersey)|pre-1927 Route&nbsp;2]] between Bordentown and Trenton in 1916, [[Pre-1927 Route 13 (New Jersey)|pre-1927 Route&nbsp;13]] between Trenton and Princeton in 1917, and [[Pre-1927 Route 16 (New Jersey)|pre-1927 Route&nbsp;16]] between Princeton and [[Bedminster Township, New Jersey|Bedminster Township]] in 1921. The current routing along pre-1927 Route&nbsp;2 became a part of [[U.S. Route 130|US&nbsp;130]] in 1926. In 1927, current US&nbsp;206 became [[New Jersey Route 39|Route&nbsp;39]] between Hammonton and [[White Horse, New Jersey|White Horse]], [[New Jersey Route 37|Route&nbsp;37]] between White Horse and Trenton, [[New Jersey Route 27|Route&nbsp;27]] between Trenton and Princeton, '''Route&nbsp;31''' between Princeton and Newton, and '''Route&nbsp;S31''' between Newton and the Delaware River. In the later 1930s, US&nbsp;206 was designated to connect US&nbsp;30 in Hammonton north to US&nbsp;6 and US&nbsp;209 in Milford; the northern terminus was moved to its current location in the 1940s. The state highways [[concurrency (road)|running concurrently]] with US&nbsp;206 in New Jersey were removed in 1953. In the 1960s, two separate [[freeway]]s were proposed for US&nbsp;206 but never built. The first freeway was to connect Hammonton south along the Route&nbsp;54 corridor toward [[New Jersey Route 55|Route&nbsp;55]] and the planned [[New Jersey Route 60|Route&nbsp;60]] in [[Vineland, New Jersey|Vineland]] and [[Millville, New Jersey|Millville]]. The other US&nbsp;206 freeway was planned in northwestern New Jersey, connecting [[Interstate 80 in New Jersey|Interstate&nbsp;80]] (I-80) in Netcong north to [[Montague Township, New Jersey|Montague Township]]. Construction began for a bypass of US&nbsp;206 around [[Hillsborough Township, New Jersey|Hillsborough Township]] in 2010 and was completed in 2021. The [[New Jersey Department of Transportation]] (NJDOT) widened the route in [[Byram Township, New Jersey|Byram Township]] to alleviate congestion, with completion in 2013.

What is now US&nbsp;206 was part of several trails used by [[Lenape]] Native Americans: the Shamong Trail, later known as the Cape May Road, ran from what is now [[Crosswicks, New Jersey|Crosswicks]] to [[Cape May, New Jersey|Cape May]]; a trail running from Trenton through Crosswicks; the [[Assunpink Trail]], later known as the Old Dutch Road, running from Trenton north to [[New Brunswick, New Jersey|New Brunswick]]; and the Great Minisink Trail, running from Navesink through [[Netcong, New Jersey|Netcong]] to Minisink Village in modern-day Montague Township.<ref>{{cite book |last = Snyder |first = John |year = 1969 |title = The Story of New Jersey's Civil Boundaries 1606-1968 }}{{full|date=March 2025}}</ref> In 1801, the Morris Turnpike was legislated to run from [[Elizabeth, New Jersey|Elizabeth]] through Netcong to [[Kittatinny Mountain|Culver's Gap]]. In 1804, the Union Turnpike was chartered to run from Morristown to the crossing at Dingman's Ferry in Montague Township. In 1814, the [[Deckertown and Newton Turnpike|Deckerton and Newton Turnpike]] branched from Newton through Deckerton, now [[Sussex, New Jersey|Sussex]], to [[New York (state)|New York]]. The Crosswicks and Trenton Turnpike was chartered in 1854; the road is now locally known as Broad Street, and was included in US&nbsp;206 west of White Horse.

Prior to 1927, what is now US&nbsp;206 in New Jersey was legislated as part of several routes. Between Bordentown and Trenton, the current alignment was designated as a part of [[Pre-1927 Route 2 (New Jersey)|pre-1927 Route&nbsp;2]] in 1916.<ref name="1920r2">{{cite book |type = Report |title = 1916 Annual Report |publisher = New Jersey Department of Transportation |date = 1916 }}</ref> Between Trenton and Princeton, present-day US&nbsp;206 became the southernmost part of [[Pre-1927 Route 13 (New Jersey)|pre-1927 Route&nbsp;13]] in 1917.

US&nbsp;206 was widened in Byram Township to six lanes. This construction follows a decade of controversy, including concerns that the widening would violate the [[Highlands Water Protection and Planning Act]] passed in 2004; an exemption to this act allowed the construction to proceed. The widening was done in order to eliminate backups on the previous two-lane stretch during rush hours.<ref name=dr>{{cite news |title = Route&nbsp;206 widening finally under way |newspaper = [[Daily Record (Morristown)|Daily Record]] |date = December 7, 2009 }}</ref> The project was slated to be finished in November 2013.<ref>{{cite web |title = Route&nbsp;206 improvement project in Byram advances toward a November completion date |publisher = New Jersey Department of Transportation |date = September 18, 2013 |url = http://www.state.nj.us/transportation/about/press/2013/091813.shtm |access-date = June 6, 2015 }}</ref>

NJDOT is planning on widening the route in Hillsborough to four lanes and adding a concrete median from Doctors Way to Brown Avenue, where the four lane highway south of the Raritan River ends. This will replace the railroad overpass that is primarily blocking the widening project. The first half, from Doctors Way to Valley Road, was to start in the middle of 2020 and was anticipated to be completed by late 2022. The second half, from Valley Road to Brown Avenue was to take place in 2022 and take two years to complete.<ref>{{cite news |url = https://www.state.nj.us/transportation/about/press/2019/030619.shtm |title = Route&nbsp;206 Bypass project begins Hamilton Road Bridge construction |date = March 6, 2019 |access-date = July 4, 2019 }}</ref>

'''U.S. Route&nbsp;206 Bypass''' ('''US&nbsp;206 Byp.''') is the designation for the '''Peter J. Biondi Bypass''' (also signed as the '''Peter J Biondi Memorial Bypass'''), a bypass of the section of US&nbsp;206 through [[Hillsborough Township, New Jersey|Hillsborough Township]], Somerset County, New Jersey. [[Chris Christie]] signed the name into law in 2013, honoring the late New Jersey assemblyman and former Hillsborough mayor [[Peter J. Biondi]].<ref>{{cite web |last1=Hirsch |first1=Rod |title=Long-Awaited Route 206 Bypass in Hillsborough to Open June 5 |url=https://www.tapinto.net/towns/hillsborough/sections/business-and-finance/articles/long-awaited-route-206-bypass-in-hillsborough-to-open-june-5 |website=TAP Into Hillsborough |access-date=15 March 2025}}</ref>

The road begins at an at-grade intersection with US&nbsp;206 and Mountain View Road and heads north as a two-lane divided road. First crossing over [[Trenton Subdivision (CSX Transportation)|CSX's Trenton Subdivision]] railroad line, it curves to the north and comes to a signalized intersection with Hillsborough Road. Continuing north, the bypass runs through farmland and woodland with some nearby development, coming to bridges over Homestead Road and the Trenton Subdivision. The next intersection is a [[quadrant interchange]] with [[County Route 514 (New Jersey)|CR&nbsp;514]]. The connector road to CR&nbsp;514 is named Service Road though a direct ramp from CR&nbsp;514 westbound to US&nbsp;206 Byp. northbound exists. From here, the road becomes four lanes wide with a concrete barrier separating the carriageways. After passing under Hamilton Road, the bypass ends at a signalized intersection with US&nbsp;206, which continues north.<ref name=GM_Byp>{{google maps |url=https://www.google.com/maps/dir/40.4780128,-74.6552422/40.5086754,-74.6337858/@40.4934379,-74.6619799,7868m/am=t/data=!3m1!1e3!4m9!4m8!1m5!3m4!1m2!1d-74.6388344!2d40.4891333!3s0x89c3e9800c75e4d7:0xc12475c426008115!1m0!3e0 |title=U.S. Route&nbsp;206 Bypass |access-date=June 11, 2021}}</ref>
