The overall project includes development of a 65-acre site along PENNDOT State Highway 412 in the City of Bethlehem, PA by the Las Vegas Sands Corporation to construct a casino and entertainment complex. The project site is part of a redevelopment plan of the overall 124-acre Bethlehem Steel Plant site which was closed in the early 1990’s. As part of the project, transportation infrastructure improvements along State Highway 412 are warranted to complement the proposed site design. These improvements include the widening of approximately 1000-feet of State Highway 412 from a four-lane undivided highway to a four lane arterial with a center median. In addition to roadway widening the project will also require intersection improvements and widening of the Minsi trail bridge, a state owned bridge which carries Stefko Blvd that T-Intersection with SH 412 as a signalized intersection immediately to the west the site access.
The Minsi Trail Bridge is a 2200-foot steel multi-girder bridge consisting of thirteen spans that traverse the Lehigh River, Consolidate Railroad tracks, and portions of the old Bethlehem Steel site. As part of the project, a portion of the existing bridge will be widened to accommodate the proposed roadway widening of SH 412 and intersection improvements to the Stefko Blvd intersection. The project also requires the reconstruction of the bridges wingwalls and extension of the abutment. Superstructure work includes demolition of portions of the deck and barrier and installation of two new steel girders framing into a fascia girder, and widening the concrete deck and placement of new parapets. Strengthening of the fascia beam is required and shall consist of installation of a bottom cover plate.
