Final stages of Pa. bridge replacement to be completed before summer

March 26, 2011

WAYNESBORO, Pa. — The final stages of a $1.9 million bridge-replacement project in Pennsylvania near the Mason-Dixon Line are under way and should be completed before summer, a Pennsylvania Department of Transportation spokesman said last week.

Whiting-Turner Contracting Co. of Baltimore started the project on Pa. 316 south (Wayne Highway) in Washington Township, Pa., in May 2010. Temporary traffic signals have been used to restrict travel to one lane over the bridge near Lyons Road.

In recent weeks, crews have been using electric blankets to warm concrete as it sets in small sections of the bridge, PennDOT spokesman Michael Crochunis said.

Concrete sets, or "cures," between 50 and 80 degrees, Crochunis said.

"They'll pour the deck when they have temperatures consistently in that range," he said.

Although the contracted work was supposed to wrap up in late April, Crochunis said it could extend for a month or more beyond that. One of the last things to be done will be rebuilding the pavement approaching the bridge to smooth it out for vehicles.

"It depends on the weather," Crochunis said of the project's schedule.

When beams were placed last October, the bridge was completely closed to traffic, which was rerouted using a half-dozen other roads.

According to online PennDOT maps, 5,900 vehicles cross the bridge each day. The road serves as a primary route between Waynesboro and Hagerstown.
