Tanager Bridge reconstruction

County Road 15 in Orono

Hennepin County is planning to replace the Shoreline Drive Bridge (County Road 15) over Tanager Lake, frequently referred to as Tanager Bridge.

Construction is scheduled to begin in March 2021. Until replacement, the bridge remains load restricted. Law enforcement is enforcing these restrictions.

Project timeline showing planning and design phases are completed. Construction and project completion are expected for 2021.

Open all

Tanager Bridge reopens to traffic

The Tanager Bridge in Orono is now open to traffic, so you can travel on Shoreline Drive (County Road 15) without using a detour route.

Be alert as work continues

Construction activities for the new bridge and around the channel will continue through the fall, and there is another planned bridge closure in September.

We will keep disruptions to a minimum whenever possible, but please expect occasional delays and impacts when traveling through the construction area.

For your safety and the safety of our crews, exercise caution and slow down.

Anticipate channel closures this summer

The Tanager Lake Channel remains open for people boating. There will be three short-term closures scheduled, lasting up to four days each, to allow crews to work on the new bridge.

We will inform people of the closure ahead of time with email updates, the project website and signage at the channel.

On Monday, May 10, the Three Rivers Park District will start a trail connection project on Shadywood Road (County Road 19) from Livingston Avenue to the Dakota Rail Regional Trail. People driving, walking and biking on Shadywood Road should anticipate intermittent, full closures. Construction is expected to be complete by the end of June.
