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 began in June 2022.

The North Shore Bridges project will be completed in 2022.
 
Open all

Bridges closed for five months

We have closed both the Hendrickson and Noerenberg bridges at the same time. This will allow us to limit closures and impacts for those traveling on North Shore Drive to just one construction season. We first communicated this closure late last fall.

Barring any delays like weather, we anticipate this project to take five months to complete.

Detour and local access

Use the detour to get around the closure

With both bridges closed, we will need to close North Shore Drive to through traffic starting June 6. The roadway will be closed the entire five months of the project. Due to location of this project, this will have an impact on you whether you drive, walk, bike or roll.

The detour for through traffic includes:

  • 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 between the bridges

Access to North Shore Drive between the two bridges will remain open to local businesses, boat launches and homes. You will need to use the following route to access these locations.

  • North Shore Drive
  • Bayside Road
  • Tonkawa Road (County Road 135)

Channel access and impacts

Both channels open

North Arm (Hendrickson) and Maxwell (Noerenberg) channels are open.

Expect short-term channel closures this summer

For short durations during construction, we will need to fully close the Hendrickson and Noerenberg channels connecting Crystal, North Arm and Maxwell bays. These closures will only occur between Monday through Thursday, and we will keep one channel open at all times to ensure access for people boating. We will inform you of these closures with signage and on the project website.

We will also be using partial closures to complete our work at various times — including on weekends. We will restrict the channel width but people boating will still be able to travel through the area. Traffic control boats will guide boaters through the channel during the partial closures.

North Shore Bridges replacement project began June 6

Hendrickson and Noerenberg bridges closing long-term

We have begun construction to replace the two bridges carrying North Shore Drive (County Road 51) over the Hendrickson and Noerenberg channels. These bridges, often referred to as the Hendrickson and Noerenberg bridges, are nearing the end of their service lives.

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.

This work concludes an effort to coordinate major work on four bridges in the Lake Minnetonka area. We completed the Narrows Bridge project in 2020 and the Tanager Bridge project in 2021.

We appreciate your continued understanding and support while we work to complete the last two bridges. We know we will have to be onsite for inspection and maintenance work from time to time, but completing this project means fewer interruptions and safer travel throughout the lakes area for many years to come.

Project overview

Hennepin County, in coordination with the City of Orono and Metropolitan Council, is planning to replace two bridges carrying North Shore Drive (County Road 51) over the Hendrickson and Noerenberg channels. Many refer them separately as the Hendrickson Bridge and Noerenberg Bridge.

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.

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.
