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 and lasting through the end of construction season.

Both roads are currently expected to reopen to traffic by the end of the week starting December 18.

Construction updates

Portland and Cedar avenues expected to reopen to traffic towards end of week of December 18

Crews will be completing final paving and other activities to ready both roads over the Portland and Cedar avenue bridges next week, starting December 18. Both roads are expected to reopen to traffic towards the end of the week in time for the holidays.

Project work week of December 4

Construction activities completed last week include:

  • Hanging initial architectural panels on the Portland Avenue Bridge 
  • Pouring concrete railings along the edge of the bridge deck at Cedar Avenue
  • Pouring the concrete approach panels at Cedar that will join the bridge deck to the roadway
  • Placing base material, grading and completing slope work at Cedar to prepare for paving the road leading up to the bridge
  • Completing prep work for pouring approach panels at Portland this week

Portland and Cedar avenue bridges expected to reopen mid-December

Reconstruction of the Portland and Cedar avenue bridges over the Midtown Greenway is entering the final phases of work and crews expect to reopen both roads to traffic by mid-December. This is a couple weeks later than previously anticipated. Work on the Cedar Avenue Bridge is slightly ahead of the Portland Avenue Bridge, and it may open sooner.

As with all major construction projects, unforeseen circumstances can cause minor delays and schedule changes. Reconstructing both bridges simultaneously has created significant efficiencies and cost savings, and has helped reduce impacts to the traveling public during construction. It has also made it possible to finish ahead of major construction on MnDOT’s multi-year 35W@94: Downtown to Crosstown project next year.

The new bridges are designed to last 100 years, and improve safety and service for all road and trail users. To maximize strength and longevity, we must allow adequate time for final construction steps, including concrete curing, before the bridges are reopened.

We appreciate your continued patience and understanding as we work to reopen the Portland and Cedar avenue bridges in the weeks ahead.

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

  • Changing traffic lanes from four 10-foot lane through lanes to two 11-foot through lanes and two 13-foot through lanes
  • Adding structural reinforcements beneath the bridge deck to extend longevity
  • Adaptable design to accommodate possible future transit infrastructure
