The I-35W Saint Anthony Falls Bridge crosses the Saint Anthony Falls of the Mississippi River in Minneapolis, Minnesota in the U.S., carrying north-south traffic on Interstate Highway 35W. The ten-lane bridge replaced the I-35W Mississippi River bridge, which collapsed on August 1, 2007. It was planned and is maintained by the Minnesota Department of Transportation (Mn/DOT). The planning, design, and construction processes were completed faster than normal because Interstate 35W is a critical artery for commuters and truck freight. The bridge opened September 18, 2008, well ahead of the original goal of December 24.
