Conway Creek (Aschoff Road) Culvert Replacement

Two culverts carrying Conway Creek under Aschoff Road in the Rhododendron area are damaged, undersized, and do not easily allow fish and wildlife to pass upstream and will be replaced with a modular bridge. 

Why

Why
To minimize potential impacts to the roadway due to flooding and to provide access for fish and other aquatic organisms to reach upstream cold-water habitat.
