June 2024 Minneapolis Central City Tunnel Project Update
Via a June 27 e-announcement from the City of Minneapolis:
The City of Minneapolis Public Works Department is constructing a new parallel storm tunnel, enlarging a portion of the existing storm tunnel, and constructing a new tunnel access in Downtown Minneapolis.
The new tunnel is being constructed parallel to the existing tunnel located under Washington Ave S between Nicollet Mall and Chicago Ave. The existing tunnel under Chicago Ave between Washington Ave S and the Mississippi River is being expanded to handle the increased stormwater capacity. The purpose of this project is to reduce pressure in the existing tunnel, provide more room for future growth, and to reduce the need for future repairs and tunnel failures.
