PACO Group, Inc. (PACO) was retained to provide cost estimating, document control, implementation of QA/QC Plan, highway/civil design, baseline preparation, baseline optimization, schedule and cost data, and support services, as a subconsultant to Arup, for the Tappan Zee Bridge Replacement/I-287 Corridor Study being performed by the New York State Thruway Authority (NYSTA).
The Authority, working in conjunction with the Metropolitan Transportation Authority and Metro-North Railroad, is working to alleviate congestion throughout the 30-mile corridor and address the structural needs of the 3.1-mile-long bridge.
The bridge connects the heavily-populated counties of Westchester and Rockland, just 13 miles north of New York City. This critical Hudson River crossing, nearing the end of its service life, was designed to handle less traffic than it does today, does not meet current seismic criteria, and has no shoulders to accommodate emergency vehicles and breakdowns. Questions to corridor congestion must address traveler and trucking needs, as well as connectivity among transit providers on both sides of the river.
