Central City Tunnel System Construction - Learn More via July 21 Virtual Open House
The City is planning to construct a new stormwater tunnel in Downtown Minneapolis. The new tunnel will be parallel to the existing tunnel located under Washington Avenue between Nicollet Mall and Chicago Avenue and under Chicago Avenue between Washington Avenue and the Mississippi River. The new tunnel will increase stormwater capacity and will reduce possible safety hazards and failure of the existing stormwater tunnel.
The project is currently in the design phase and includes community outreach activities to inform the public on project schedule and staging. The final design for the parallel tunnel is anticipated to be completed in early 2021 and construction is tentatively scheduled to begin in late summer/early fall 2021.
The link to the virtual open house will be posted the morning of July 21, 2020.
