Franklin Avenue Bridge restoration

County Road 5 in Minneapolis

In 2017, Hennepin County reconditioned the Franklin Avenue Bridge (County Road 5) in Minneapolis. The bridge spans West River Parkway and the Mississippi River. Prior to the reconditioning, crews rehabilitated this historic structure during two construction seasons between 2015 and 2016.

Current work

Franklin Avenue Bridge reopens

In late October, crews completed restoration work on the Franklin Avenue (County Road 5) Bridge. All lanes are open for people using the road, as well as the bicycle and pedestrian trails.

This year's restoration work, which began in April, included:

  • Repairing concrete substructures
  • Painting the bridge deck and underside, as well as treating traffic railings to protect and preserve the bridge
  • Reestablishing vegetation along both ends of the bridge

We thank you for your patience and understanding during this year's work.

Project work summary

During 2016, the Franklin Avenue Bridge was reconstructed. Accelerated bridge construction techniques were used so construction crews could remove and replace the entire bridge deck in just 17 weeks -- shortening the need for an extended closure and detour.

Significant engineering and construction planning have resulted in a historically accurate, multi-modal bridge deck configuration that will serve bicyclists, pedestrians and motorists well into the future.

Motorists can now enjoy a brand new structural bridge deck across the Franklin Avenue Bridge. Pedestrians and cyclists are able to cross the bridge using the newly constructed -- and separated -- facilities.

Construction timeline

The 2015 season included below deck concrete rehabilitation and manufacture of "precast" bridge deck panels that were placed during the 2016 bridge closure. These panels were made at a site, adjacent to the river, just south of the Washington Avenue Bridge. This allowed use of river transportation to float these panels down the river, and these segments were hoisted by water borne cranes into their final positions.

Crews also salvaged remnant piers from 1889.

During the 2016 construction season, the bridge was closed for complete deck removal and replacement.

In 2017, bridge restoration activities, along with final tasks and clean up were completed.
