| Abstract: | The former Betzwood Bridge, located in Montgomery County, Pennsylvania, was an alternative
to using US Route 422 to cross the Schuylkill River to visit popular destinations such as the King
of Prussia Mall or Valley Forge National Park. However, since the bridge was demolished in
1993 there has been no alternative but to use the US Route 422 Bridge. The Pennsylvania
Department of Transportation has since realized the need to rebuild the former bridge to alleviate
the present delays experienced by US Route 422 travelers. Briefly stated, BHP's scope of work
for this project involved designing and constructing a new five span, two lane, 745-foot bridge
that will span the Schuylkill River, as well as the active Norfolk Southern Railroad, widening a
half mile of Trooper Road (S.R 3051), and redesigning the intersections of Trooper Road and
Valley Forge Road (SR 0023) and Trooper Road and Audubon Road, as well as making
improvement to the US Route 422 off ramp. To achieve these designs the four main areas of
roadway design, bridge superstructure and substructure design, and traffic design had to be
evaluated. The following sections will look into each one of these areas in greater detail and
explain the methodology behind the new proposed designs. |
