Aerial View of Shaft Construction Along I-35W in Minneapolis
Taken February 2022
The Minnesota Department of Transportation built this stormwater storage facility along I-35W in Minneapolis to capture runoff that once overwhelmed the corridor's drainage system during heavy rain. The project uses a series of large-diameter shafts bored into bedrock beneath the freeway, connected to underground tunnels that hold water until it can be released or treated. MnDOT undertook the work as part of a broader effort to reduce flooding on this stretch of I-35W, which runs through a residential section of the city just east of the highway.
