Detours, closures and travel considerations

Brown Road Bridge open to traffic

The Brown Road Bridge (County Road 146) is open to traffic.

The newly-constructed bridge offers improved driving surfaces, wider shoulders, updated railings and erosion protections. It replaces a bridge built in 1921 that lacked these key features and had fallen in a key bridge rating.

Construction began in June. And, crews worked over the summer to complete this project and reopen the road by fall.

We thank you for your patience and understanding during this year's construction.

Project information

Built in 1921, the old bridge was 23 feet long, 24 feet wide and utilized steel beams with a concrete deck. It was a two-lane bridge with no shoulders and no pedestrian accommodations. The sufficiency rating for the bridge was 48.9 out of a possible 100 and was classified as scour critical. The new bridge addressed these issues with wider shoulders, updated crash-worthy railings and eliminated the scour critical classification.
