2023 Bridge Rehabilition

The City of Traverse City is preparing to complete the multi-year bridge rehabilitation project with construction on the N. Cass Street Bridge and the S. Union Street Bridge. Major bridgework is slated to begin January 30, 2023. The two projects were bundled to attract bridge contractors to bid on the project, drive competitive pricing, and complete in the shortest amount of time possible.


S. Union Street Bridge
The S. Union Street Bridge rehabilitation work is anticipated to begin in 2023. Improvements include replacement of existing concrete deck and steel beams on the existing foundation, widening sidewalks to the extent possible, installation of an MDOT crash tested/approved bridge railing detail painted black along sidewalk edge with historic balustrade pedestrian railing to restore original aesthetic treatment, and a pedestrian railing approaching bridge.

N. Cass Street Bridge
The N. Cass Street Bridge rehabilitation work is anticiapted to begin in 2023. Improvments include replacement of existing deck, concrete beams and railing on the existing foundation, widening sidewalks to the extent e, installation of an MDOT crash tested/approved bridge railing detail painted black with aesthetic treatment at ends, and pedestrian railing approaching bridge.


Accessible Pedestrian Detour

Closures & Detours

The construction will generate dust and noise. Traffic delays are expected. Pedestrian and vehicular detour maps have been developed to assist those traveling throughout the City. East bound traffic on the south state Street alley between Union and Cass will be maintained. West bound through traffic will be prohibited. The Cass Street Pedestrian Tunnel will remain open. However, the accessible ramp will be closed. Those needing an alternative route, will be directed to cross the Grandview Parkway at Union Street. The Boardman River will be closed to traffic during construction. As the summer season approaches, the work on the river will conclude on weekdays as much as possible, but may include weekends to complete the project in a timely manner. 

Businesses will remain open along the construction routes. 


City staff is coordinating the project with Michigan Department of Transportation’s (MDOT) Traverse City Transportation Service Center and Local Agency Bridge program that will cover approximately 90% of the constrution cost. Cost for the two bridge projects is nearly $4,000,0000, with design and engineering at $221,400.
