Description 

Unusual cantilever/arch design

FROM THE 1996-2001 PENNSYLVANIA HISTORIC BRIDGE SURVEY: The 3-span, 132'-long reinforced concrete cantilevered variable-depth slab bridge built in 1927 has a 62'-long main span flanked by two, 31'-long, cantilevered arm approach spans supported on concrete piers. The cantilever design is illustrated in period textbooks and was believed to have the advantage of giving the appearance of an arch where a real arch would be exceedingly costly on account of foundation conditions. Typically, there is an expansion joint at the crown of the center span. The pier and cantilever arms on each side compose a unit. Built in 1927, the bridge is 1 of 2 examples of this design in the Lancaster County (the other is BMS# 36 1010 0050 1342, built in 1917, NR-listed), but no other examples of the rare type/design have been identified in the state. The bridge is historically and technologically significant.
