Taconic Parkway Bridge Design Services
Project Overview: 
As part of a Design Services Agreement with the State, McLaren provided engineering services for the replacement and rehabilitation of a dozen bridges throughout Region 8. Among the bridges assigned under this agreement are the Taconic State Parkway over Angell Hill Road, in Columbia County, Route 6 over the West Branch of the Croton River, Route 121 over the Stone Hill River, Route 22 over Muscoot Reservoir and numerous bridges along 9A in Westchester County, and Route 9D in Putnam and Dutchess Counties. The Bruckneck Tunnel was also inspected and rehabilitated under this program.
McLaren's Role: 
McLaren provided Phases I-VI of the design services associated with the replacement of both of the Taconic State Parkway Bridges. Work involved removal of a three-span structure and replacement with a new single span bridge on an existing horizontal and vertical alignment. The proposed superstructure consisted of pre-stressed concrete arch beams with stone facing on the fascia. Other areas of involvement included M&PT, approach work, paving, pavement markers, striping and utilities, and guide railing.
