North Shore Bridges replacement

County Road 51 in Orono

Hennepin County, in coordination with the City of Orono, is expected to replace two bridges carrying North Shore Drive over the Hendrickson and Noerenberg channels. These bridges are frequently referred to separately as the Hendrickson Bridge and Noerenberg Bridge.

Construction is anticipated to begin as early as June 2022.

The North Shore Bridges project will be completed in 2022.

Project coming in June

We anticipate replacement work to begin as early as June, and take up to five months to complete. We will provide updates as we get closer to construction.

Preconstruction activities before

In May, Metropolitan Council began relocating their underground utility line ahead of the bridges replacement. Their work will have minimal impacts to North Shore Drive users. Throughout the month, there will also be additional work happening near both the bridges such as private utilities relocating their service lines and removing trees within Hennepin County right-of-way to replace the bridges.

New bridges will require less maintenance

The new bridges will have the same dimensions and look to help preserve existing space for adjacent properties and the natural features along the channels.
When complete, the new bridges will reduce the need for frequent maintenance activities in the future and meet today's and future travel needs.

Plan ahead for detour

We will close and replace both bridges at the same time. Closing both bridges will allow our crews to complete all construction work and limit closures to just one construction season.
During the closure, people using North Shore Drive will need to use the detour taking:

  • North Shore Drive (County Road 19)
  • Bayside Road (County Road 84)
  • Leaf Street (County Road 84)
  • Fox Street (County Road 84)
  • Old Crystal Bay Road (County Road 84)

Local access and impacts during construction

Access to North Shore Drive between the two bridges will remain open to local businesses, boat launches and residences. People will need to use North Shore Drive (County Road 19), Bayside Road (County Road 84) and Tonkawa Road (County Road 135) to access these locations.

The Hendrickson and Noerenberg channels connecting Crystal, North Arm and Maxwell bays will close for short durations during the construction. There will also be intermittent partial closures -- including on weekends. The channel width will be restricted, but people boating will still be able to travel through the area.

We will inform people of these closures with signage and traffic control boats to guide boaters through the channel.

Preparing for North Shore Bridges project in 2022

We plan to begin replacing the two bridges as early as late spring/early summer 2022.

Replacing the bridges will reduce the need for frequent maintenance in the future and better meet present and future travel needs. The new bridges will have the same dimensions as the current bridges with an updated look, thereby preserving existing space and natural features along the channels.

The project will impact how people travel the area, as our current plan is to close and replace both bridges at the same time. This will allow our crews to complete all construction work and limit closures to just one construction season.

We encourage you to begin planning for this as you prepare for your daily travel, as well as any celebrations, special events and leisure activities.

Watch our video presentation to learn more

We posted a five-minute video of a presentation on the project website for you to view at your convenience.

The video covers:

  • Anticipated construction schedule
  • Detour routes during construction (new detour route as of April 2022; please check project information tab)
  • Local access to homes, businesses and destinations between the bridges
  • Best way for you to stay connected

We will also have some more information about a Metropolitan Council project planned prior to the bridges project.
