Pongratz Road culvert replacement location


The culvert on Pongratz Road, between Tolke Road and Ardabeth Lane, is too small and often clogs. We are replacing the culvert with a larger metal pipe to improve water flow and allow fish to pass upstream.

We are replacing the culvert at the same time as the bridge over Whitcher Creek, east of Tolke Road. More information about the bridge replacement is available on the project page

The project is starting in summer 2021 (tentative) and ending in October. Pongratz Road will close during construction. 

Construction start (expected): August 2021
Construction finish (expected): 9/30/2021


Update 7/28/2021: Pongratz Road will close Aug. 2-30 for culvert replacement. The Pongratz Road bridge replacement project will follow.
