Greensburg, PA — Entrance Ramp Culvert Relined with Snap-Tite
Culvert Below Highway Entrance Ramp Fails, Relined with No-Dig Snap-Tite®
Corrugated metal pipe (CMP) culverts are failing at an alarming rate throughout the U.S. These culverts were installed 40 to 50 years ago and have exceeded their design life. A 36-inch culvert failed under a SR30 road off-ramp in Greensburg, PA. The Pennsylvania Department of Transportation (Penn DOT) District 12, Westmoreland County, could not dig up this storm drain culvert because it was located underneath the piers that support an entrance ramp bridge onto SR30. The bridge piers were directly on top of the culvert; so, the DOT needed a no-dig solution to repair the culvert without major road closures or expensive excavation.
Snap-Tite® representative Joe Nagy worked with Penn DOT’s County Manager Tim Cook to provide the DOT with the right materials for this emergency project. The material chosen for the culvert rehabilitation project included 30-inch Snap-Tite® liner pipe, which was delivered in nine-foot sections for a total of 400 feet of pipe.
