Erdman Anthony provided preliminary engineering and final design services for
improvements to a 6.5-mile section of US 22/322 (SR 0022, Sections A09, A10, and
A11) as a major engineering subconsultant. The previous two-lane roadway, which
ran through a geographically restricted corridor between the Juniata River and
Shade Mountain, was replaced by a four-lane, limited access expressway. The
highway provides an important link between Pennsylvania State University's main
campus and the Harrisburg metropolitan area and points east.
Anthony's portion of the design included more than 22,000 feet of retaining
walls, one along the river and one supporting a bifurcated section of mainline.
Highway stability along steep slopes was a key concern our staff addressed with
independent pile remediation consisting of both H-piles and micropiles. Our
staff also completed a hydrologic and hydraulic report on the Juniata River and
five tributaries, and designed a storm water system that includes over 490
inlets and 5,400 linear feet of cross culvert, in addition to spring boxes and
swales. Due to the project's location in a detailed FEMA study area, Erdman
Anthony prepared a Conditional Letter of Map Revision to redefine the 100-year
flood boundary. The completed highway, which has been heralded as a noteworthy
engineering feat in local and national trade publications, will improve both
travel times and traffic safety. The project also restored a section of the
historic Pennsylvania Canal, remodeled a lock keeper's house into a park and
educational center, and provided ramps to a boat launch on the Juniata River.
