Interstate 35E / 35W Minnesota


Interstate 35 splits into Interstates 35E and 35W to serve St. Paul (east) and Minneapolis (west). The two split at Burnsville in the south suburbs, with I-35W leading north to Bloomington and Richfield and I-35E angling northeast through Apple Valley, Eagan and Mendota Heights.

I-35W includes a High Occupancy Toll (HOT) lane in both directions from the split with I-35E northward to the interchange with Minnesota 65 and Interstate 94 at Downtown Minneapolis. The freeway sees two east-west segments, one along side Minnesota 62 (Crosstown Highway) and another parallel to I-94 on the south side of the Minneapolis central business district.

Beyond the separation with I-94, Interstate 35W branches northeasterly, first crossing the Mississippi River on the St. Anthony Falls Bridge and then turning east to Roseville and the west end of Minnesota 36, a freeway extending east to Maplewood. North from there, I-35W straddles the New Brighton and Arden Hills city line to Mounds View and Shoreview. U.S. 10 briefly ties into the freeway along this stretch.

I-35W curves easterly again at Blaine to Lino Lakes. The freeway traverses an area of wetlands from Rice Lake Chain of Lakes Regional Park Preserve through to Peltier and Rondeau Lakes to recombine with Interstate 35E at a wye interchange in south Columbus.

Interstate 35E meanwhile continues the exit numbering system of I-35 through the St. Paul area. The freeway winds northward through Lilydale and across the Mississippi River to enter south Saint Paul at the Crosby Nature Area. An ess curve takes the freeway eastward onto a parkway section ahead of Downtown. The portion of I-35E between MN 5 and I-94 includes a truck prohibition (over 9,000 pounds) due to the parkway status of the route.

Once in Downtown St. Paul, Interstate 35E briefly commingles with Interstate 94 & U.S. 12-52 before again curving northward to Maplewood. A due north trajectory takes the route to Little Canada and a dog leg along side Interstate 694 to Vadnais Heights.

The remainder of I-35E travels northward to White Bear Lake, White Bear Township, North Oaks and Lino Lakes. A rural end point lies north of Centerville, with I-35W merging into I-35E from the left.

Collapse of Interstate 35W Mississippi River Bridge

The Interstate 35W bridge over the Mississippi River collapsed during the peak traffic hours of August 1, 2007, near Downtown Minneapolis. Without any notice, the deck truss bridge (built in 1964, opened in 1967, 1907 feet long, 14 spans) plummeted into the waters of the Mississippi River some 64 feet below, sending drivers and their vehicles into the river in an instant.1 A total of 111 vehicles were on the portion of bridge that collapsed; 13 people died and 145 people were injured in the tragedy. Inadequate load capacity of the gusset plates (support elements along the under side of the bridge) failed, causing the bridge collapse to occur. An in depth report from the NTSB on the event is available here.

A $15-million contract to remove the bridge debris was awarded to Carl Bolander & Sons Co. on August 8, 2007. Crews used three cranes to lift the bridge deck segments for their move to a staging area for analysis by NTSB officials.

During this period without the crossing, commuters were directed on Interstate 94 and Minnesota 280 to circumvent the bridge area of Interstate 35W. MnDOT blocked Minnesota 280's intersections with County Road B, Broadway Street N.E., Walnut Street and Roselawn Avenue in an effort to temporarily upgrade all of Minnesota 280 into a full freeway (Minnesota 280 existed previously as a freeway halfway between Interstates 94 and 35W).

The replacement span opened well ahead of schedule on September 18, 2008 and carries ten overall lanes of traffic. Named the St. Anthony Falls Bridge, the span is 189 feet wide, 76 feet wider than the original span, and includes both full inside and outside shoulders.

Parallel/Historic U.S. Routes

Interstate 35W parallels historic U.S. 65 north from Burnsville to Downtown Minneapolis and old U.S. 8 from Minneapolis north to Columbus. Interstate 35E combines with U.S. 10 from Downtown St. Paul to Interstate 694 while paralleling U.S. 61 to the west from St. Paul north to Columbus.

Planned Improvements

Major reconstruction underway between spring 2013 and spring 2016 involves upgrading Interstate 35E between University Avenue (Exit 107C) in St. Paul and Little Canada Road (Exit 113) in Little Canada. Work involves expanding the freeway to eight overall lanes, with three general purpose lanes and a MnPass (HOT) lane in each direction. Construction replaces the bridges for I-35E over Pennsylvania Avenue, the Soo Line Railroad and Cayuga Street as part of a relocation of the freeway several hundred feet east. Work also includes removing the interchange with Pennsylvania Avenue and replacing it with a new folded-diamond interchange at Cayuga Street.3

Further north through the I-35E project area, the overpass for Maryland Avenue at Exit 109 was replaced during summer 2012. New bridges were constructed over the freeway at Arlington Avenue, Wheelock Parkway and Larpenteur Avenue (Exit 110A). The spans for I-35E above Roselawn Avenue and County Road B were also replaced. The full cloverleaf interchange at Minnesota 36 will receive certain modifications but otherwise remain the same. The I-35E overpasses above MN 36 however will be replaced. An unbonded concrete overlay was used for the new surface throughout the project area.3

The MnPASS lanes on I-35E between St. Paul and Little Canada commenced operations on November 30, 2015. The HOT lanes use the innermost lane of each roadway.5


Interstate 35E was the last Minneapolis-St. Paul area Interstate to be completed. Delays due to litigation and compromise pushed the final four mile segment of I-35E back to an opening on October 15, 1990, 19 years after work started. This stretch through the West Seventh area runs northeast from south St. Paul to Interstate 94 in Downtown.

I-35E through south St. Paul was first envisioned in 1920 and planned more formerly as a six-lane freeway known as the Pleasant Avenue corridor in 1955. Initial work on the route was halted in 1972, after only a year of progress. During that time, area residents formed a citizens group against the highway known as RIP-35E, for "Residents In Protest", complete with a tombstone symbol for the road. Their efforts led to political action at both city and state levels, resulting in an extensive reevaluation of the freeway plans.

A plan to construct a parkway in place of a high-speed freeway was nearly reached, when labor unions gave their input and swayed the opinions of public officials. The prior plan did not include a direct connection with I-94, but the new plan did. This resulted in a law suit filed by RIP-35E in March 1983 over the connection issue, which the group contended was sufficient using city streets to continue northward along I-35E beyond Downtown. A federal judge disagreed and ruled against RIP on February 9, 1984, allowing for the direction connection.

Some work resumed along the parkway section of I-35E in 1983 due to an out-of-court agreement. The end result of the RIP-35E group and other compromises is a four-lane parkway with a restriction against commercial trucks and a low 45 Mile Per Hour speed limit. Additionally median trees, shrubs and decorative lighting and fencing were incorporated into the landscaping and design of the roadway. Total cost of the parkway section of I-35E between the Mississippi River and I-94 was $68 million.2

Completion dates per Minnesota Official Highway Maps:

History of Split Routes

In their guidelines of signing Interstates, the American Association of State Highway and Transportation Officials (AASHTO) mandated that all suffixed Interstate highways be removed from the Interstate system in the late 1960s and 1970s. This resulted in many changes to the system, including:

  • Interstate 5W to I-505 and I-580 (Oakland to south of Tracy) in California
  • Interstate 15E to I-215 in California (former U.S. 395)
  • Interstate 15W to the Western Interstate 86 in Idaho
  • Interstate 35 to I-135 in Kansas
  • Interstate 70N to I-70 and Interstate 70S to I-270 in Maryland
  • Interstate 75E to I-75 in the Tampa Bay Area (original I-75 was renumbered I-275)
  • Interstate 80N to I-680 in Iowa
  • Interstate 80N to the Western I-84 in Oregon, Idaho, and Utah
  • Interstate 80S to I-76 in Colorado
  • Interstate 80S to I-76 in Ohio, Pennsylvania, and New Jersey
  • Interstate 81E to I-380 in Pennsylvania

Most of these conversions were completed during the 1960s and 1970s. The Western Interstate 84 was among the last, as it was converted by 1980. However, there were two exceptions remaining in the system: Interstate 35 splits twice into Interstate 35E and Interstate 35W, once in the Dallas/Fort Worth metro area and again in the Minneapolis/St. Paul metro area. The reason these split routes still remain is that neither city wanted to relinquish the routing of Interstate 35. AASHTO gave in to these demands, and the split suffixed routing remains in both Texas and Minnesota.

A new set of split routes appeared in 2013 when Interstates 69C and 69E were established in South Texas by an act of Congress. The circumvented the authority of AASHTO and the mandate that no new suffixed routes be designated. Interstate 69W was established a year later.

Downtown Minneapolis Inset - 1975 Minnesota Official Highway Map
Minnesota 36 provided the link between the two sections of Interstate 35W between Hennepin Avenue and New Brighton Boulevard (U.S. 8) until the freeway was completed. The interchange with I-335, a planned east-west connector to I-94, held up completion of this section until it was canceled in 1975.
Minneapolis and St. Paul Inset - 1983-84 Minnesota Official Highway Map
Interstate 35E opened to traffic between Interstate 35 at Burnsville and Minnesota 77 at Eagan in 1982. The freeway north to Interstate 494 at Mendota Heights was completed by late 1985.4
Initial construction on the parkway section of Interstate 35E ran northward from Minnesota 5 (West 7th Street) to the Linwood Park vicinity in 1980. The route however would not open for another ten years.
The Parkway section of I-35E defaults northbound motorists onto I-94 east while access to I-35E southbound is only available directly from I-94 west. Local streets are required to make the missing connections.
