This bridge replaced a seven-lane steel girder bridge, constructed in 1960 by the Minnesota Highway Department. When it was built, it replaced a former bridge, located just to the east of the current bridge site, that carried US 65. Approaches to the former bridge 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]

<span class="mw-page-title-main">I-35W Mississippi River bridge</span> Bridge in Minneapolis, Minn., US, that collapsed in 2007

The I-35W Mississippi River bridge was an eight-lane, steel truss arch bridge that carried Interstate 35W across the Mississippi River one-half mile downstream from the Saint Anthony Falls in Minneapolis, Minnesota, United States. The bridge opened in 1967, and was Minnesota's third busiest, carrying 140,000 vehicles daily. After only 39 years in service, it experienced a catastrophic failure during the evening rush hour on August 1, 2007, killing 13 people and injuring 145. The National Transportation Safety Board (NTSB) cited a design flaw as the likely cause of the collapse, noting that an excessively thin gusset plate ripped along a line of rivets. Additional weight on the bridge at the time of failure was also cited by the NTSB as a contributing factor.

I-35W & 46th Street station is a Metro Orange Line bus rapid transit station located in Minneapolis, Minnesota. In addition to the BRT service, the station is also served by Metro route 578. The station was constructed as part of the I-35W/Minnesota State Highway 62 Crosstown Commons reconstruction project and opened in 2010. Consisting of two levels, one on East 46th Street, and the other in the median of Interstate 35W, the station was the first of its kind in Minnesota. The station allows for transit routes operating on I-35W to stop for riders without leaving the region's high occupancy toll lane system. The station was designed in anticipation of full bus rapid transit service along I-35W to downtown Minneapolis, a vision that was realized in 2021 with the opening of the Metro Orange Line. The station cost $4.5 million to build.
