Bridge 9 Program
Starting in 2020, the City of Minneapolis will begin repairs on Bridge 9 in downtown Minneapolis.
Project status
Background
Bridge No. 9 was constructed in 1922 by the Northern Pacific Railroad to carry freight over the Mississippi. The City of Minneapolis acquired this bridge in 1986 and converted the bridge to a pedestrian use bridge in 1999. The bridge currently provides a Mississippi River crossing for the Dinkytown Greenway bike trail.
Over the years the bridge has deteriorated substantially, and rehab is required. To preserve the historic resource of the bridge the City has opted for a repair/rehabilitation program. The Bridge 9 program is a multi-year program aimed to address the Northern Pacific Railroad Bridge deficiencies. The program has prioritized critical rehabilitation needs of the bridge and phased them to be repaired in the coming years. The expected completion date of the program is 2026.
For more information on work to be completed on Bridge 9, see the Bridge 9 Piers Diagram.
Project limits
The bridge begins near the corner of 20th Ave South and Bluff St South and crosses the Mississippi River landing on the Dinkytown Greenway. The rehabilitation work will primary be concentrated on the piers and foundation.
Phases
This program will be completed in phases. See the phases of repair and rehabilitation below.
