County Trunk Highway D Reconstruction

CTH D Reconstruction Project Area and Bridge Closure Map

Motorists are asked to follow the posted detour route utilizing USH 45, State Trunk Highway (STH) 33, and STH 144 (Main Street). The Woodford Drive bridge over the Eisenbahn State Trail has been closed to all traffic for the duration of the project to restrict traffic utilizing the one-lane wooden bridge to bypass construction and not for structural reasons.

Local residents are asked to use extra care when driving in the construction area and obey all flagmen and construction signs. Alternate routes should be used if possible to avoid delays.

Project updates will be posted here periodically and on Washington County's Facebook page.

Thank you in advance for your patience and understanding as we improve Washington County's roadways.
