The Rock Creek Road Culvert Replacement Project replaced a failed culvert that carried a tributary of Rock Creek thirty feet under Rock Creek Road. The bottom of the old culvert rusted out, allowing it to clog with dirt and rocks. After a heavy rain, it backed up stormwater on the uphill side of the road, creating a lake that threatened the road embankment and nearby property. The new culvert is four feet in diameter and made of a non-rusting material called high density polyethylene.
