Hempt Road Bridge
From Historic Bridge Inventory: The bridge carries a 2 lane road over a stream in a rural area of active farms and late-20th-century residential subdivisions northwest of Mechanicsburg. At the bridge's northeast quadrant are horse barns and a ranch house (ca. 1970). At the northwest quadrant is a mid-19th-century farmhouse with Colonial Revival alterations. A horse track is to the south of the bridge. West of the bridge is a short-span concrete slab bridge with pipe railings (ca. 1915) that is on the section of Hempt Road bypassed in the early 1950s. The 2-span, 42'-long, prestressed concrete adjacent box beam bridge built in 1952 is historically and technologically significant as an early, unaltered, multiple span example of its type. The bridge has fasciae-mounted metal beam guide railings. The state highway department in cooperation with the Concrete Products Company of America (Pottstown) was among the leaders in the development and use of prestressed concrete as a bridge material in the United States. In 1950-51, they introduced a standard, short-span (less than 30') hollow box beam bridge as an economical alternative for use on lower volume roads in the state. The survey has identified over 220 pre-1957 examples with more than 35 dating to before 1953. It is the early box beam bridges, complete with original railings, that best illustrate the historical and technological significance of the standard design.
