Stone Arch Bridge Upgraded for Flooding

Aug. 5, 2024
It cost $115 million to rehabilitate the 129-year-old structure

Gov. Kathy Hochul announced on Friday that bridge reconstruction on the bridge carrying U.S. Route 1 has finished after four years. 

The project rebuilt the 129-year-old stone arch bridge, adding new support structures to make it durable and resilient to flooding, according to Hochul. 

A cast-in-place concrete liner was installed under the bridge, and new foundation elements were drilled into the underlying rock, according to officials. 

The bridge was widened, and new pedestrian walkways were added to improve safety and access. New pedestrian safety improvements were also added at the intersection of U.S. Route 1 and Mamaroneck Avenue, including signals, curb ramps and crosswalks. 

"The reconstruction of the Route 1 bridge in Mamaroneck is the final piece of a transformative project that will keep travelers safe and help keep some of the busiest roads in the Lower Hudson Valley open and functioning regardless of the challenges that Mother Nature throws at us," Hochul said. 

The $115 million project began in 2020 to upgrade several bridges that were prone to flooding in Westchester County. It also looked to upgrade routes, so they are better equipped for the impacts of climate change. 

The Lower Westchester Bridge Bundle initiative replaced two bridges on Saw Mill River Parkway and the East Lincoln Avenue bridge.
