NYSDOT Bridges Design Build in Lower Westchester

Bridges for NYSDOT Design Build in Lower Westchester Rendering

McLaren’s Bridge/Highway/Rail team has begun work on the $115 million Design-Build of the Lower Westchester bridges with Halmar International. During this initial phase, our surveyors and geotechnical engineers were in the field completing pre-construction evaluations at three locations just north of NYC in preparation for the replacement of five full bridges and a culvert.

This NYSDOT infrastructure project (D900049) aims to mitigate frequent flooding concerns of the sites’ overpasses and adjacent highways. It includes 1,700 feet of soil stabilization along the Saw Mill River Parkway and extensive bridge, highway, drainage, utility and Intelligent Transportation System (ITS) improvements along each high-volume corridor. The project also includes environmental permitting.
