Minnesota State Highway 36 is a highway in Minnesota, which runs from its interchange with Interstate 35W in Roseville and continues east to its eastern terminus at the Wisconsin state line (at Stillwater), where it becomes Wisconsin Highway 64 upon crossing the St. Croix River. A portion of Highway 36 is a major freeway in suburban Minneapolis – Saint Paul.

Highway 36 is 22 miles (35 km) in length.

State Highway 36 serves as an east–west route between the cities of Roseville, Little Canada, Maplewood, North St. Paul, Oakdale, Oak Park Heights, and Stillwater.

Highway 36 is a limited-access freeway from its interchange with Interstate 35W in Roseville eastward to Interstate 35E in Little Canada, and about two miles beyond. The freeway section ends east of its interchange with U.S. Highway 61, at its signal-controlled intersection with English Street in Maplewood. Highway 36 becomes an at-grade expressway at this point. For about four miles outside of the I-494 / 694 loop, the expressway section of Highway 36 has a speed limit of 65 MPH (105 km/h).

Highway 36 crosses the St. Croix River via the historic Stillwater Lift Bridge between Stillwater and Houlton, WI. The route becomes Wisconsin Highway 64 upon crossing the bridge into Wisconsin. Planning is taking place to replace the bridge, which reached its practical capacity in 1990. Because the bridge is considered historically significant, this has become a heated issue.

State Highway 36 was authorized in 1933. The route was paved by 1940.

From 1934 to 1982, Highway 36 used to be significantly longer. The route had turned southward along I-35W, Washington Avenue, and Cedar Avenue in Minneapolis; and connected to what is now State Highway 77 (Cedar Avenue Freeway). In Eagan, old Highway 36 had intersected the Chicago and North Western Railway at-grade, at the Nicols Station Crossing. The section of old Highway 36 that ran along Washington and Cedar Avenues in Minneapolis was turned back to county maintenance in 1982, and is currently a section of Hennepin County Road 152.

Highway 36 did not originally reach the Wisconsin state line at the St. Croix River. Part of old State Highway 212 in Oak Park Heights and Stillwater was renumbered as Highway 36 in 1983. This section of present day Highway 36 still carries the old Highway 212 mile markers.[citation needed]

The section of Highway 36 in North St. Paul was closed in 2007 from April to September. The highway was rebuilt to freeway standards during this time between White Bear Avenue in Maplewood and Highway 120 (Century Avenue) in North St. Paul. The changes included grade-separated intersections with no interchanges or access within North St. Paul. The full closure in 2007 allowed the project to be completed faster and at a lower cost. It also increased safety for construction workers. The Highway 36 reconstruction project in North St. Paul was completed in 2008. The budget of the project was $24 million.

An interchange is currently proposed for the junction between Highway 36 and Hilton Trail in Pine Springs. It has not yet been scheduled for construction. The project will also include two roundabouts on Hilton Trail on either side of the highway, one at 60th Street North and another at an extension of Viking Drive.
