Jefferson County will replace an existing culvert located just east of the Black Mountain Drive and Sullivan Drive intersection. This pipe replacement is to address degrading infrastructure and prevent failure of the pipe and roadway.

Project Scope:

The project entails replacing an existing corrugated metal pipe located within the public roadway with a new reinforced concrete pipe. This process will involve removal of the roadway, excavation, pipe removal, pipe installation, and roadway repairs. 

Project Schedule:

The project is currently under design. Construction for this culvert is anticipated to take place in fall of 2023.

Project Impact on Traffic:

During construction, the contractor will be closing the roadway on Sullivan Drive to perform the culvert replacement. Alternative routes will be provided, and impacted residents will receive notice prior to construction. This work is anticipated to take approximately two weeks to complete. 

Jefferson County will provide an updated notice of traffic impacts before construction activities begin.
