Harrisburg, PA – The Pennsylvania Department of Transportation (PennDOT) today announced that on Thursday, March 29, weather permitting, its contractor is scheduled to activate temporary traffic signals and set barrier that will restrict traffic to a single 11-foot-wide lane on the bridge that carries Route 16 over the Conococheague Creek as crews begin demolition of the existing bridge superstructure west of Greencastle Borough in Antrim Township, Franklin County.

PennDOT advises motorists that initially they may encounter flaggers alternating traffic through the work zone as crews conduct preparatory work and install the temporary traffic signals approaching the bridge. Once installed, the signals will assist in alternating motorists through the work zone as crews demolish the existing span, set new bridge beams and construct a new concrete bridge deck. This portion of Route 16, locally known as Buchanan Trail, averages more than 11,800 vehicles traveled daily.

PennDOT awarded the $2,294,584 contract on November 14, 2017, to Cottle’s Asphalt Maintenance, Inc. of Everett, Bedford County. Work includes removing and replacing the 77-year-old structurally deficient concrete deck and steel I-beam superstructure under staged construction, drainage work, roadway approach slab and pavement reconstruction, and new guiderail, signs and pavement markings.

The existing bridge was built in 1941. Once the superstructure is replaced and the roadway reopens to unrestricted traffic, it will be removed from the list of structurally deficient bridges.
