I-35W Minnesota River bridge

The I-35W Minnesota River Bridge is an under construction bridge over the Minnesota River. The replacement bridge project started in mid 2018, and it will be finished in late 2021. The new bridge will have eight lanes, four lanes in each direction. The inner lanes are MnPass HOV lanes, and a trail will be built on the northbound span. The entire project costs $147.6 million dollars.[1][2] The bridge is 1,361 feet (415 m) long, and 170 feet (52 m) wide.[3]

The former I-35W Minnesota River Bridge was a seven-lane steel girder bridge that carried Interstate 35W across the Minnesota River between Bloomington and Burnsville, Minnesota. It was built in 1960 by the Minnesota Highway Department. When it was built, it replaced a former bridge that carried US 65. It has had issues with flooding, with a 1965 flood putting the causeway just south of the bridge completely underwater. MnPass lanes were added in 2009.[5]
