PA Turnpike to Demolish Bridge in Dauphin County at Milepost 250

Five-hour roadway closures to occur between Harrisburg East and Lebanon/Lancaster Interchanges.

Harrisburg, PA The Pennsylvania Turnpike Commission (PTC) advises motorists that overnight on Sunday, Dec. 5, its contractor will be demolishing an overhead bridge across I-76 at Milepost 250 in Dauphin County.

The demolition of the overhead bridge is slated to occur at 12:01 a.m. through 5 a.m. on Sunday, Dec. 5. During this time all eastbound and westbound traffic between the Harrisburg East Interchange, Exit 247, and Lebanon Lancaster Interchange, Exit 266, will be detoured.

A replacement bridge will be constructed along the existing bridge alignment. During construction of this new bridge, traffic will be maintained on the temporary bridge which has been erected to the east of the existing bridge. The necessary Turnpike closure will enable construction crews to safely demolish the existing overhead bridge.

Eastbound Detour

Motorists heading east during this time will exit at the Harrisburg East Interchange, Exit 247, and follow I-283 North to US 322 East to SR72 to the reenter the Turnpike at the Lancaster/Lebanon Interchange, Exit 266.

Motorists heading west during this time will exit at the Lebanon/Lancaster Interchange, Exit 266, and follow SR72 North to US 322 West to I-283 South to reenter the Turnpike at the Harrisburg East Interchange, Exit 247. 


The existing bridge, built in 1950, is a single span, rigid frame reinforced concrete bridge that is approximately 78 feet long with a cross section that is approximately 37 feet from parapet to parapet, including two travel lanes and a raised sidewalk. The permanent replacement bridge will be a two-span rolled steel girder structure that is 130 feet long with a cross section that will safely accommodate foot traffic. It is anticipated that the new bridge will be completed in the fall of 2022.

The bridge carries approximately 9,000 vehicles in daily traffic along State Route 441 (North Union Street) over the Turnpike in Lower Swatara Township, Dauphin County.
