'''Interstate&nbsp;35''' ('''I-35''') is a major [[Interstate Highway]] in the central [[United States]]. As with most primary Interstates that end in a five, it is a major cross-country, north–south route. It stretches from [[Laredo, Texas]], near the [[Mexico–United States border|Mexican border]] to [[Duluth, Minnesota]], at [[Minnesota State Highway 61]] (MN&nbsp;61) and 26th&nbsp;Avenue East.<ref name="Google">{{google maps |url = https://maps.google.com/maps?f=d&hl=en&geocode=3966640746460723679,27.524700,-99.502890%3B9356109620576285556,46.801921,-92.071031&saddr=I-35+N+%4027.524700,+-99.502890&daddr=46.808637,-92.06131&mra=dme&mrcr=0&mrsp=1&sz=13&sll=46.798649,-92.0644&sspn=0.053116,0.115356&ie=UTF8&ll=40.713956,-97.382812&spn=30.012924,59.0625&z=4 |title = Overview Map of I-35 |access-date = February 15, 2008 }}</ref> The highway splits into [[Interstate 35E (disambiguation)|I-35E]] and [[Interstate 35W (disambiguation)|I-35W]] in two separate places, the [[Dallas–Fort Worth metroplex]] in [[Texas]] and at the [[Minnesota]] twin cities of [[Minneapolis–Saint Paul]].

At {{convert|1568|mi|km}}, I-35 is the ninth-longest Interstate Highway following [[Interstate 94|I-94]], and it is the third-longest north–south Interstate Highway, following [[Interstate 75|I-75]] and [[Interstate 95|I-95]]. Even though the route is generally considered to be a [[Pan-American Highway|border-to-border highway]], this highway does not directly connect to either international border. I-35's southern terminus is the [[traffic signal]] at Hidalgo Street in Laredo, Texas, just short of the Mexican border. Travelers going south can take one of two toll bridges across the [[Rio Grande]] and the border, either straight ahead into the [[Juárez–Lincoln International Bridge]], or via [[Interstate 35 Business (Laredo, Texas)|Business Interstate&nbsp;35-A]] (Bus. I-35-A) through downtown Laredo into the [[Gateway to the Americas International Bridge]]. To the north, I-35 terminates in Duluth, Minnesota, with connections to Canada from the Interstate's terminus via MN&nbsp;61 to [[Grand Portage (community), Minnesota|Grand Portage]], or north to the border at [[International Falls, Minnesota]], via [[U.S. Route 53 in Minnesota|U.S. Route&nbsp;53]] (US&nbsp;53) in Duluth.

In addition to the Dallas–Fort Worth and Minneapolis–Saint Paul areas, the major cities that I-35 also connects to include (from south to north) [[San Antonio, Texas]]; [[Austin, Texas]]; [[Oklahoma City, Oklahoma]]; [[Wichita, Kansas]]; [[Kansas City, Missouri]]; and [[Des Moines, Iowa]].

[[File:Endofi35.jpg|thumb|right|I-35 starts at this [[traffic signal]] in Laredo, Texas]]

I-35 northbound begins at a traffic-signaled intersection with [[Interstate 35 Business (Laredo, Texas)|Bus. I-35-A]] in [[Laredo, Texas]], just north of the [[Rio Grande]] and the international border between [[Mexico]] and the US. It has a {{convert|17|mi|km|adj=on}} [[concurrency (road)|concurrency]] with [[U.S. Route 83 in Texas|US&nbsp;83]]. Through [[Webb County, Texas|Webb]], [[La Salle County, Texas|La Salle]], and [[Frio County, Texas|Frio]] counties, it has a mostly north-northeastern course, turning more northeasterly around [[Moore, Texas|Moore]].<ref name="txdot-map">{{cite map |title = Texas Official Travel Map |author = [[Texas Department of Transportation]] |publisher = Texas Department of Transportation |year = 2006 }}</ref> It then cuts across the corners of [[Medina County, Texas|Medina]] and [[Atascosa County, Texas|Atascosa]] counties before entering [[Bexar County, Texas|Bexar County]] and [[San Antonio]].

I-35 is named the [[Pan-American Highway|Pan Am Expressway]] in San Antonio. There, it has brief concurrencies with [[Interstate 10 in Texas|I-10]] (with it [[U.S. Route 87|US&nbsp;87]]) and [[Interstate 410|I-410]], and it serves as the northern terminus of [[Interstate 37|I-37]]. I-35 heads northeast out of the city toward the state capital, [[Austin, Texas|Austin]].

In Austin, I-35 is the Interregional Highway and has a concurrency with [[US 290]] through Downtown Austin.<ref name="about">{{cite web |last = Bear |first = Jacci Howard |url = http://austin.about.com/od/roadmaps/f/ih35.htm |title = Are Interstate Highway 35 and Interregional Highway 35 the Same Road? |work = About.com |access-date = December 7, 2006 |archive-url = https://web.archive.org/web/20081207201156/http://austin.about.com/od/roadmaps/f/ih35.htm |archive-date = December 7, 2008 }}</ref> Throughout Austin, elevated express lanes were constructed on either side of the original [[freeway]]. Prior to this expansion, this section included an [[Level crossing|at-grade railroad crossing]], which is extremely unusual for a freeway. From Austin, I-35 goes through [[Round Rock, Texas|Round Rock]], [[Temple, Texas|Temple]], [[Pflugerville, Texas|Pflugerville]], and [[Waco, Texas|Waco]]. In [[Belton, Texas|Belton]], south of Temple, it serves as the current eastern terminus for [[Interstate 14|I-14]]. In Waco, I-35 is known as the Jack Kultgen Freeway, and begins its concurrency with [[U.S. Route 77 in Texas|US&nbsp;77]]. The campuses of both the [[University of Texas at Austin]] and [[Baylor University]] are located adjacent to I-35.

I-35 then heads to [[Hillsboro, Texas|Hillsboro]], where it splits into [[Interstate 35W (Texas)|I-35W]] and [[Interstate 35E (Texas)|I-35E]] and runs through the [[Dallas]]–[[Fort Worth]] area. The official milemarkers, along with the route of US&nbsp;77, follow I-35E through Dallas—I-35W, which is {{convert|85|mi|km}} in length, carries its own mileage from Hillsboro to [[Denton, Texas|Denton]], as though it were an I-35 loop. In Dallas, I-35E is the R.L. Thornton Freeway south of [[Interstate 30|I-30]], which picks up the name heading east. North of I-30, it is the Stemmons Freeway.

After passing through Dallas and Fort Worth, I-35's two forks rejoin each other in Denton near the [[University of North Texas]] campus. The unified Interstate then continues north to [[Gainesville, Texas|Gainesville]] before crossing the [[Red River of the South|Red River]] into Oklahoma.

===Oklahoma===
{{main|Interstate 35 in Oklahoma}}
[[File:I35oklahoma102.jpg|thumb|left|400px|I-35 in [[Goldsby, Oklahoma]], at milemarker&nbsp;102]]

In Oklahoma, I-35 runs from the Red River at the Texas border to the Kansas state line near [[Braman, Oklahoma|Braman]]. It passes through or adjacent to many of the state's major cities. From south to north, these cities include [[Ardmore, Oklahoma|Ardmore]], [[Pauls Valley, Oklahoma|Pauls Valley]], [[Purcell, Oklahoma|Purcell]], [[Norman, Oklahoma|Norman]], [[Moore, Oklahoma|Moore]], [[Oklahoma City]], and [[Edmond, Oklahoma|Edmond]]. In [[Downtown Oklahoma City]], I-35 has a major junction with [[Interstate 40 in Oklahoma|I-40]] and spurs into [[Interstate 235 (Oklahoma)|I-235]] through the north central inner city as heavy traffic follows through the city into the northern area of the state.

===Kansas===
{{main|Interstate 35 in Kansas}}
[[Image:Kta view.jpg|thumb|right|A view from the I-35 portion of the Kansas Turnpike, between mileposts&nbsp;29 and 30]]

Between the Oklahoma state line and [[Emporia, Kansas|Emporia]], I-35 is part of the [[Kansas Turnpike]]. This section of Interstate serves [[Wichita, Kansas|Wichita]] and passes through the [[Flint Hills]] area. At Emporia, I-35 branches off on its own alignment. This free section of I-35 provides access to [[Ottawa, Kansas|Ottawa]] before entering the [[Kansas City Metropolitan Area]], where it serves [[Johnson County, Kansas|Johnson County]] and [[Kansas City, Kansas]].

Of note on the route, at several points between Cassoday and Emporia in the Flint Hills, dirt driveways that provide direct access without a ramp, for cattle trucks, may be found in either direction along the highway.

'''BETO Junction''' is a highway intersection in [[Coffey County, Kansas]], that is the intersection of [[U.S. Route 75 in Kansas|US&nbsp;75]] and I-35. It derives its name from the four major cities nearest the intersection: [[Burlington, Kansas|Burlington]], [[Emporia, Kansas|Emporia]], [[Topeka, Kansas|Topeka]], and [[Ottawa, Kansas|Ottawa]]. It is located {{convert|16|mi|km}} north of Burlington at exit&nbsp;155. Historically, the intersection referred to as "BETO Junction" before I-35 was constructed was located on the old US&nbsp;75 alignments {{convert|2|mi|km|spell=in}} south and {{convert|2|mi|km|spell=in}} east, near [[Waverly, Kansas]].

=== Missouri ===
{{main|Interstate 35 in Missouri}}
[[File:STH72244.JPG|thumb|left|[[Christopher S. Bond Bridge, Kansas City|Bond Bridge]] carries I-35 in Kansas City]]

I-35 enters Missouri {{convert|2|mi|km|spell=in}} southwest of Kansas City's [[Central Business District]] as a six-lane highway. After merging with [[Southwest Trafficway]] and Broadway, it becomes eight lanes and continues north to downtown Kansas City, where it serves as the west and north legs of the [[Downtown freeway loop (Kansas City)|downtown freeway loop]]. Along the north edge of the loop, I-35 joins with [[Interstate 70 in Missouri|I-70]] immediately west of Broadway and carries six lanes of traffic with a speed limit of {{convert|45|mph|km/h|abbr=on}}. Upon leaving the loop, [[Interstate 29 in Missouri|I-29]] begins, concurrent with I-35. The two Interstates cross the [[Missouri River]] together on the [[Christopher S. Bond Bridge, Kansas City|Bond Bridge]].

After crossing the river, I-29 and I-35 split. I-35 heads north to [[Cameron, Missouri]], and then continues northward to the Iowa state line.

===Iowa===
{{main|Interstate 35 in Iowa}}
[[File:I-35 nb ia exit 182.jpg|thumb|300px|I-35 in Iowa, near exit&nbsp;182. The town of [[Swaledale, IA|Swaledale]] is about {{convert|1|mi|km|spell=in}} to the east.]]

In the southern sections of the state, I-35 is parallel to [[U.S. Route 69 in Iowa|US&nbsp;69]] for much of its course.

In [[Des Moines, IA|Des Moines]], I-35 has a {{convert|12|mi|km|adj=on}} [[concurrency (road)|overlap]] with [[Interstate 80 (Iowa)|I-80]]. The concurrency takes place northwest of the downtown district of the city. At exit&nbsp;127 of I-80, the overlap turns east and terminates at exit&nbsp;137 via an interchange with [[Interstate 235 (Iowa)|I-235]].

North of Des Moines, I-35 is mainly parallel with US&nbsp;69, traversing a vast and rural area of Iowa.<ref>{{cite map |title = Motor Carriers' Road Atlas |author = [[Rand McNally]] |location = Chicago |publisher = Rand McNally |page = 38 |edition = Deluxe |year = 2007 }}</ref>

I-35 is part of the [[Avenue of the Saints]] between [[Clear Lake, Iowa|Clear Lake]] and St. Paul, Minnesota. A four-lane link has been completed between Clear Lake and [[Interstate 380 (Iowa)|I-380]] in [[Waterloo, Iowa|Waterloo]], [[Iowa]].

===Minnesota===

[[File:N terminus I35.JPG|thumb|300px|left|I-35's northern terminus is at this intersection with London Road ([[Minnesota State Highway 61|MN&nbsp;61]]) in [[Duluth, Minnesota|Duluth]], [[Minnesota]], with [[Lake Superior]] in the background.]]

At [[Medford, Minnesota|Medford]], [[Minnesota]], the on- and offramps lead to [[roundabout]]s rather than standard cross intersections.<ref>{{cite magazine |author = Federal Highway Administration |publisher = Federal Highway Administration |url = https://www.fhwa.dot.gov/publications/focus/04sep/05.cfm |magazine = Focus: Accelerating Infrastructure Innovations |title = Excellence in Highway Design 2004 |access-date = February 12, 2006 |date = September 2004 |volume = 21 |issue = 8 |id = FHWA-HRT-04-029 |issn = 1060-6637 |url-status = live |archive-url = https://web.archive.org/web/20100610021917/http://www.fhwa.dot.gov/publications/focus/04sep/05.cfm |archive-date = June 10, 2010 }}</ref> This is the first site in the state linked to a major highway to use roundabouts.

I-35 splits again into [[Interstate 35W (Minnesota)|I-35W]] and [[Interstate 35E (Minnesota)|I-35E]] in the [[Minneapolis]]–[[Saint Paul, Minnesota|Saint Paul]] area. The mile- and exit-numbering sequence continues along I-35E. At one sharp turn in I-35W near the junction with I-94, drivers are advised to slow to {{convert|35|mph|km/h|abbr=on}} (although many drivers are able to maintain the speed limit of {{convert|55|mph|km/h|abbr=on}}). It is not possible to go from westbound I-94 to northbound I-35W, from southbound I-35W to eastbound I-94, and vice versa, without resorting to surface streets.

On I-35E in Minnesota between [[Minnesota State Highway 5|MN&nbsp;5]] and [[Interstate 94 in Minnesota|I-94]], in both directions, trucks weighing more than {{convert|9000|lb|kg}} are banned from the freeway, and the speed limit drops to {{convert|45|mph|km/h|abbr=on}}. This section was not completed until the late 1980s (although the route was cleared and graded earlier) due to opposition from the historic Crocus Hill neighborhood, which sits only a few hundred feet from the alignment. The four-lane alignment, "parkway" design was a compromise. The truck bypass for this section is signed on [[Interstate 494 (Minnesota)|I-494]] and [[Interstate 694 (Minnesota)|I-694]] to the east of Saint Paul.

I-35 has an [[Interchange (road)|interchange]] with [[Interstate 535|I-535]]/[[U.S. Route 53 in Minnesota|US&nbsp;53]] in [[Duluth, Minnesota]], known locally as the "Can of Worms". This [[Junction (road)|junction]] features a pair of left exits from I-35, a stoplight, and lane drops over the I-35 bridge.<ref>{{google maps |url = https://maps.google.com/maps?q=Duluth+MN&ll=46.765515,-92.12255&spn=0.005762,0.01663&t=h |title = Overview Map and Aerial Photo of the Can of Worms Interchange |access-date = June 8, 2009 }}</ref>

The national northern terminus of I-35 is at an [[Intersection (road)|intersection]] in eastern Duluth. Drivers' options include merging with London Road/[[Minnesota State Highway 61|MN&nbsp;61]] northbound, proceeding through the stop lights onto 26th&nbsp;Avenue East, or turning left onto London Road southbound.

==History==
Some portions of I-35 in Oklahoma City were already built in 1953, before the Interstate system was created.<ref name="oklahoman1"/> Through [[Norman, Oklahoma|Norman]], [[Oklahoma]], the Interstate opened in June&nbsp;1959. In [[Moore, Oklahoma|Moore]], it opened in two parts: the northern half, connecting Moore to Oklahoma City, opened in January&nbsp;1960. The southern half, linking it to Norman, was opened to traffic in June&nbsp;1967.<ref name="oklahoman2">{{cite news |last = Medley |first = Robert |title = Highways Continue to Drive Economy |work = The Daily Oklahoman |location = Oklahoma City |date = June 29, 2006 |page = 1D }}</ref>

I-35 through Oklahoma largely parallels [[U.S. Route 77|US&nbsp;77]]. This is in large part due to efforts of the towns of [[Wynnewood, Oklahoma|Wynnewood]], [[Paoli, Oklahoma|Paoli]], and [[Wayne, Oklahoma|Wayne]], which fought to keep I-35 as close as possible to US&nbsp;77. This was successful due to a threat from Governor [[Henry Bellmon]] to build a toll road rather than I-35, and legislation preventing state funds for the Interstate from being spent if it were more than {{convert|1|mi|km|spell=in}} from the U.S. Route.<ref>{{cite book |last = McNichol |first = Dan |title = The Roads that Built America: The Incredible Story of the U.S. Interstate System |location = New York |publisher = Sterling |year = 2006 |isbn = 1-4027-3468-9 }}{{page needed |date= March 2013}}</ref>

I-35 was completed in Oklahoma in 1971, when parts of the Interstate running through [[Carter County, Oklahoma|Carter Co.]] and [[Murray County, Oklahoma|Murray Co.]] were opened to traffic.<ref name="oklahoman1">{{cite news |last = Cockerell |first = Penny |title = 50 Years: As the Intersection of Interstates 35, 40, and 44, Oklahoma Is at America's Crossroads |work = The Daily Oklahoman |location = Oklahoma City |date = June 29, 2006 |page = 2A }}</ref>

The final segment of I-35 (as originally planned) to open was in north-central [[Iowa]], between [[Mason City, Iowa|Mason City]] and [[US 20|US&nbsp;20]] near [[Iowa Falls, Iowa|Iowa Falls]]. This segment was delayed due to some controversy. Originally, I-35 was to follow the alignment of [[US 69|US&nbsp;69]] from [[Des Moines, Iowa|Des Moines]] to the [[Minnesota]] border, but Mason City's business community lobbied for the route to be moved closer to their city. On September&nbsp;1, 1965, the alignment was changed to instead parallel [[US 65|US&nbsp;65]] through northern Iowa, which brought the highway much closer to Mason City. This created a long diagonal section through [[Wright County, Iowa|Wright]] and [[Franklin County, Iowa|Franklin]] counties. Local farmers objected to their farms being bisected into triangular pieces, and resulting litigation delayed I-35 for several years. A November&nbsp;1972 ruling rejected a lawsuit filed by the farmers, and the final segment of I-35 was allowed to proceed, eventually opening in 1975.

The [[Paseo Bridge]] over the [[Missouri River]] in Kansas City, Missouri, was replaced by the [[dual-span]] [[cable-stayed bridge|cable-stayed]] [[Christopher S. Bond Bridge (Kansas City)|Christopher S. Bond Bridge]] in December&nbsp;2010.<ref>{{cite press release |url = http://www.modot.org/kansascity/newrelease/District4News.shtml?action=displaySSI&newsId=63363 |title = All Interstate 29/35 Ramps and Lanes Open Tomorrow: On-Budget and Six Months Ahead of Schedule |first = Meghan |last = Jansen |publisher = Missouri Department of Transportation |date = December 17, 2010 |access-date = November 27, 2011 |archive-url = https://web.archive.org/web/20120320043006/http://www.modot.org/kansascity/newrelease/District4News.shtml?action=displaySSI&newsId=63363 |archive-date = March 20, 2012 |url-status = dead }}</ref>

[[File:Interstate 35 29 map.png|thumb|[[Interstate 29|I-29]] and I-35]]

The proposed [[Trans-Texas Corridor]] toll-road project included one proposal (TTC-35) to primarily parallel I-35 from the Mexican border up to the Oklahoma border.<ref>{{cite web |work = [[Trans-Texas Corridor]] Study |title = I-35 Corridor Section |url = http://www.keeptexasmoving.com/projects/ttc35/ |archive-url = https://web.archive.org/web/20070509033839/http://www.keeptexasmoving.com/projects/ttc35/ |archive-date = May 9, 2007 }}</ref> There are major disagreements as to what impact this parallel route would have on I-35 in terms of traffic, maintenance, and commerce.

The Trans-Texas Corridor was first proposed by [[Texas]] [[List of Governors of Texas|Governor]] [[Rick Perry]] in 2002. It consisted of a {{convert|1200|ft|m|adj=on}} wide highway that also carried utilities such as electricity, petroleum, and water as well as railway track and fiberoptic cables.<ref name="highway to hell">{{cite news |last = Kovach |first = Gretel |title = Highway to Hell? |work = [[Newsweek]] |date = December 10, 2007 |url = http://www.thedailybeast.com/newsweek/2007/12/01/highway-to-hell.html |access-date = December 7, 2007 }}</ref> In July&nbsp;2007, US Representative [[Duncan L.
