Construction has started on a major, multi-faceted project in Westchester County to replace four bridges, renovate another, and convert a large culvert into a small bridge.
The project, which includes drainage improvements and the reconstruction of roadways prone to flooding, will enhance safety and improve the region’s resiliency during storm events.
The New York State Department of Transportation is replacing two bridges and a large culvert at East Lincoln Ave. over the Hutchinson River Parkway and Hutchinson River between Pelham and Mount Vernon, as well as two bridges on the Saw Mill River Parkway over Saw Mill River in Pleasantville. A bridge on U.S. Route 1 over Mamaroneck River in Mamaroneck is being upgraded.
The project also will reconstruct bridge approaches and nearby highway intersections, enhance pedestrian safety by upgrading sidewalks, curb ramps, crosswalks and pedestrian signals to meet Americans with Disabilities Act standards, modernize traffic signal operations with new coordinated and interconnected signals, and install new barriers and bridge railings.
The new bridges on the Saw Mill River Parkway over the Saw Mill River will be elevated to meet 100-year flood projections. A 1.3-mile stretch of newly constructed roadway will be stabilized to divert water from the road and mitigate settling.
The U.S. Route 1 stone arch bridge over the Mamaroneck River in Mamaroneck will be reinforced and strengthened with a steel liner installed underneath the bridge. The structure supporting part of Harbor Island Park at the southeast corner of U.S. Route 1 and Mamaroneck Avenue will be removed and replaced.
Field preparation, surveying and utility work will be underway this summer, with project construction beginning in the fall.
The $115 million project is set for completion in fall 2022.
