Harrisburg, PA – The Pennsylvania Department of Transportation (PennDOT) today announced updates on the work regarding U.S. 422 in North Londonderry Township near Palmyra Borough in Lebanon County.
Since the beginning of July, geotechnical and structural engineers have assessed the site and ground conditions and have completed a design for a concrete slab to cover the eastbound and westbound section of U.S. 422. The contractor will be installing 84 steel columns referred to as micropiles, which will be embedded into the rock bed below the surface to support the slab. Excavation at the site is scheduled to begin, weather permitting, on Monday, July 29, with the micropile work beginning on August 5.
While the department had previously anticipated opening the road before the beginning of the school year, the void and subsequent work needed to make sure U.S. 422 is safe for motorists will require a closure until late November 2019.
The official detour, which is currently in place, involves Route 117 to U.S. 322 to Route 934 and back to U.S. 422. Motorists are asked to use the official detour as local roads are not designed for the volume of traffic that is typically on U.S. 422.
Although not part of the official detour, adjustments were recently made to the signals at the intersection of U.S. 422 and Apple Blossom Road to accommodate local traffic.
