Closures, impacts and access

Construction activities scheduled to begin June 1

Starting June 1, Hennepin County is scheduled to begin rehabilitation of the Shadywood Road Bridge over Narrows Channel, commonly referred to as the Narrows Bridge. 

Crews will remove the bridge deck, restore components underneath and replace the bridge deck. This will ensure a longer service life for the bridge and reduce the need for frequent maintenance activities in the future.

Bridge to close

Due to its structural design and site constraints, the bridge will need to close for up to three months to safely and effectively complete the rehabilitation work.

Expect short-term channel impacts

The Narrows Channel underneath will also close, but for shorter durations. We anticipate two, five-day closures at the channel. There will also be intermittent partial closures, where the channel width will be restricted, but people boating can still have access. 

Detour and access 

During the closure, people driving will need to use the detour taking:

  • Highway 7
  • Westedge Boulevard/County Road 44
  • Commerce/Bartlett Boulevard (County Road 110)
  • Shoreline Drive (County Road 15)

People walking, biking and rolling will need to use alternative routes, but will need to remain outside of the construction area.

Additional projects nearby

We anticipate there will be other projects in the area in 2020. These include two-county led reconstruction efforts:

We are working to coordinate these efforts and all other construction and maintenance activities to the best of our ability.

Roadway and bridge maintenance activities in the area

In addition to the projects, the county will also complete regular short-term roadway and bridge maintenance activities. These activities include:  

  • roadway repaving, sweeping and cracksealing  
  • bridge inspections and flushing 
  • tree trimming 

Impacts will vary depending on the work needed, but most work is done alongside traffic or with brief lane closures. We will provide updates via email as the projects near.  

Also, the county is working with municipalities and the Minnesota Department of Transportation to coordinate on various other projects that will be happening this year and hope to minimize any overlap.

Project information

The current bridge, constructed in 1964, is in good overall condition, but needs some work to ensure a longer service life. When completed, the new bridge should last an additional 40 years
before any major reconstruction work is required.


Rehabilitation work on the Narrows Bridge will include:

  • Repairing the abutment foundation
  • Restoring the bridge bearings
  • Repainting all steel structures under the bridge
  • Pouring the bridge deck
  • Replacing traffic barriers on the bridge
