WHAT YOU CAN’T SEE (YET) MAY SURPRISE YOU – If you travel U.S. Route 422 between its exits at Sanatoga and Route 724 with any frequency, you already know 1) there’s construction afoot; 2) that a 40 mph speed limit is in effect across the length of the zone because of that construction; and 3) police regularly enforce the speed limit to ensure public and worker safety. What you may not know is the extent of progress being made on the first of the new bridges that will carry traffic across the Schuylkill River between the 724 and Armand Hammer Boulevard exits. Concrete Jersey barriers and construction rigging make it difficult to see from the highway itself. It’s evident from the river level, however, as photographed Sunday (Jan. 19, 2013). Several footings have been poured (above), and massive girders set (below), to support the future roadbed. It’s distance across the river, so far, can be judged by the inset at top.
