Greenway bridges

Portland Avenue (County Road 35) and Cedar Avenue (County Road 152) Midtown Greenway bridges reconstruction projects 

Hennepin County is reconstructing the Portland Avenue (County Road 35) and Cedar Avenue (County Road 152) bridges over the Midtown Greenway in Minneapolis in 2017.

Reconstruction is needed to address safety and structural issues due to the age of the bridges. Both of the century-old bridges will be reconstructed in their original historic style, and receive design and functional improvements.

Work is expected to take place over one construction season, beginning in early spring 2017

Construction updates

Construction is currently expected to begin in late April 2017 and be complete by the end of the year.

Detours, closures and travel considerations

Updated January 2017

Both bridges and related sections of the Midtown Greenway are currently open. Reconstruction work has not yet begun.

The roadways over the bridges will be closed for the duration of the projects. Trail impacts will be minimized whenever possible, but occasional closures, detours and other impacts should be expected throughout 2017.

Project information

Hennepin County is reconstructing the Portland Avenue and Cedar Avenue bridges over the Midtown Greenway in Minneapolis in 2017. To minimize impacts on trail and road users, reconstruction work will occur on both bridges simultaneously and major closures will be coordinated between the two projects when possible.

Reconstruction of the bridges is needed to address safety and structural issues due to the age of the bridges.

Design changes

During reconstruction, improvements will be made to the design and function of the bridges, while maintaining their historic architectural styles.

Portland Avenue planned improvements

  • Widening sidewalk on bridge deck from eight to 10 feet
  • Changing traffic lanes from three ten-foot through lanes to two 13-foot through lanes
  • Adding a three-foot buffer to the existing 6-foot bike lane
  • Adaptable design to accommodate possible future transit infrastructure
