South Main Street, Bridge Over Washington Secondary (Conrail)

The South Main Street Bridge over Washington Secondary (Conrail) is located in Phillipsburg Town, Warren County. The bridge was built in 1910 and is a two span, simply supported, concrete encased bridge. This structure is classified as an orphan bridge. The bridge has a span length of 53 feet, and a width of 61 feet including11.8-foot-wide sidewalks. The overall condition of the structure is poor due to the condition of both the superstructure and substructure. The bridge is functionally obsolete due to substandard vertical and lateral clearances. In addition, it is critical due to its nonredundant construction. The deck is in serious condition due to its underside exhibiting severe scaling/spalling with exposed, rusted reinforcement in several bays. The superstructure is in poor condition due to the loss of concrete encasements and corroded bottom flanges of the stringers accompanied by steel exfoliation. South Main Street within the project limits is a north-south urban principal arterial with a posted speed limit of 25 mph. The undivided roadway section is comprised of one travel lane in each direction and no shoulders. The bridge is located adjacent to the historic Union Station and a Warren Through Truss bridge, Structure No. 2160-166. Structure No. 2160- 166 carries South Main Street over the Norfolk Southern Lehigh rail line which is an active freight line. The existing vertical clearance is 17 4. The intent is to enhance safety by addressing deficiencies. It seeks to minimize environmental impacts and develop a cost-effective solution to replace the structure in combination with lowering the tracks to achieve the desired vertical under clearance. This solicitation is to provide Preliminary Engineering Services for the project. Technical proposals are being solicited for Preliminary Engineering, Final Design and Construction Engineering Services. However, services under the original agreement shall be limited to the completion of Preliminary Engineering services. Final Design Services and Construction Engineering Services may be initiated at a later date as a CONSULTANT AGREEMENT ADDENDUM, at the sole discretion of the State.
