DALLAS TWP. — A section of Hildebrandt Road will close for a month this summer for culvert replacement work, James May, spokesman for the state Department of Transportation said Monday.
A section of Hildebrandt Road, starting near the intersection with Route 309 and East Center Hill Road is scheduled to close after July 4 as Pennsylvania American Water, and UGI temporarily relocate utility lines to allow PennDOT to replace a deteriorating culvert, May said.
“The pipe has been there for a long time,” May said. “It is rusted on the bottom and beginning to collapse.”
The decomposing pipe previously created an indentation in the road surface, spurring complaints from motorists. Last year, PennDOT did a temporary fix by applying more asphalt on the road section while a plan was developed for a permanent repair, May said.
The project is tentatively scheduled to take 30 days to complete, depending on the weather, he said, adding crews have a “small window of time” to finish the project before the Dallas School District resumes classes in September.
“We are working closely with local emergency responders and the school district to make this as painless as possible on the local community,” May said in an email. “The reason we are doing this work now is because school is not in session and we won’t have to impact all the school traffic.”
Traffic detours will route drivers to the new section of Upper Demunds Road that intersects with Route 309 near the Dallas Township Municipal Building, to Lower Demunds Road to Hildebrandt Road while a new culvert is installed, May said.
The culvert funnels a stream, which is the “beginning stages of Toby Creek” under Hildebrandt Road, May said. The stream will be pumped through a temporary structure to the opposite side of the road to maintain the water flow and natural environments downstream, he said.
A seven-foot-two-inch high by 11-foot-four-inch wide pipe will be placed in smaller sections and assembled on sight, May said, adding the culvert would normally be installed in one piece; however, overhead utility wires will prevent cranes from maneuvering the large pipe safely.
“There are about 3,000 bolts that are needed to hold the sections of pipe together,” May said.
