morris B25-57 LANDING RD BRIDGE Final.pdf

This document is a final project specification for the Replacement of Bridge No. 1400-073 on Landing Road in Roxbury Township, Morris County, New Jersey, prepared by Morris County. The project involves staged construction requiring complete removal and disposal of the existing filled concrete arch bridge, including its asphalt overlay, reinforced concrete deck, guide rails, bridge railing, and associated features. The replacement structure will be a two-span prestressed concrete adjacent box beam bridge supported on reinforced concrete abutments, a reinforced concrete wall pier, and drilled micropiles. The scope of work encompasses construction of a cast-in-place reinforced concrete deck with curbs, parapet with railing, pilasters, sidewalk, approach roadway work including milling and resurfacing, intersection realignment and reconstruction of two intersections, traffic signal construction, and utility relocation. Additional work includes drainage improvements, pavement removal at adjacent acquired properties, revegetation and seeding of disturbed areas, and comprehensive maintenance and protection of traffic throughout construction. The contractor must establish and maintain signing and traffic control devices to preserve two-way traffic in accordance with approved traffic control plans and coordinate operations with local police.

The specification emphasizes the contractor's responsibility for comprehensive project management including coordination with local authorities and traffic management throughout the staged construction process. The project requires removal of all existing bridge components and features that interfere with construction of the proposed structure and approach roadways, with particular attention to the proper disposal of removed materials. Work on approach roadways includes sawcutting and removing existing pavement, removing guide rails, and constructing new HMA roadway pavement, sidewalks, and guide rails, with new traffic stripes applied to all new pavement surfaces.
