SR 135 over Strahl Creek Bridge Rehabilitation

HWC is providing road and bridge design for this bridge rehabilitation project. The existing bridge is a 3-span continuous concrete slab bridge that is in horizontal and vertical curves along SR 135 in Brown County. The structure is deteriorated, hydraulically deficient, and has scour problems. The main scope of work is a superstructure replacement with roadway improvements to tie back into the existing superelevated roadway and safety improvements to upgrade the existing guardrail. This project will also evaluate the potential of adding a 4th span to the bridge to provide the necessary hydraulic capacity. The maintenance of traffic will utilize temporary portable signals for phased construction.
