15th & 16th Ave S Bridges over Midtown Greenway Corridor                               

Project Type:
15th and 16th Ave S bridges over the Midtown Greenway are in the 2013-2017 five-year Capital Program under the Midtown Corridor Bridge Preservation Program.  The bridges are contributing elements to the railroad grade separation Historic District, which was listed in the National Register of Historic Places in 2005.  The design team has worked with Mn/Dot Cultural Resource Center, State Historic Preservation Office (SHPO), and Mn/DOT Bridge Office to maintain the historic character-defining features of these bridges.

15th and 16th Ave S bridges over the Midtown Greenway were built in 1916.  During a cursory review of the corridor it has been observed that these bridges have undergone both uniform and differential settlement.  This has led to large cracking in the abutment wall, back wall and wing walls.  Exposed reinforcement steel, crumbling concrete, and accelerated deterioration of the bridges' key elements are shortening the bridges usable life and become a safety issue.

The proposed rehabilitation of the bridges addresses the deficiency of the bridges and extends the service life of the bridges by full or partial deck-resurfacing, slope stabilization, wing wall repairs, repairing the sidewalk and railings, foundation stabilization, superstructure strengthening, and adding approach panels.

Project Limits:
The project is located in south Minneapolis on 15th Ave S and 16th Ave S bridges over the Midtown Greenway Corridor.

Construction Start Date:
May 2013

Length of Construction:
May 2013 through October 2013.

Traffic Impact:
Bridges will be closed during construction.
