NEWS | Westchester County Celebrates the Opening of the New Glen Island Bridge Six Months Ahead of Schedule. For H&H, this project reflects our long-standing commitment to delivering complex infrastructure solutions that preserve critical transportation connections while extending the life and performance of historic structures through engineering innovation, collaboration, and technical expertise. Our work on this bridge continues a legacy that dates back to the bridge’s original 1927 design by Waddell & Hardesty. Congratulations to Westchester County, Kiewit, and all of the stakeholders involved in delivering this important project for the community. #designedtoamaze #engineeredtolast #hhsquad
Westchester County Executive Ken Jenkins joined County officials, project engineers and members of the community to celebrate the opening of the newly rehabilitated Glen Island Bridge, six months ahead of schedule. The milestone marks a major step forward in the County’s ongoing rehabilitation of the historic Glen Island Bridge, originally constructed in 1930 and serving as the only access point for entering Glen Island Park. The transition restores traffic to the permanent structure, while final construction and restoration work continues through the remainder of the year. Significant work has already been completed as part of the rehabilitation project, including the repair of steel girders, installation of the bridge floor beams, concrete bridge deck, movable span grid deck, pedestrian railings, the bridge’s electrical and mechanical systems, bridge and approach sidewalks, and traffic and pedestrian railing ahead of the traffic shift. Additional work currently underway includes testing of the mechanical and electrical systems ahead of the scheduled reopening of the navigation channel on May 22. Jenkins said: “Today marks another important milestone in this project and in our continued investment in Westchester County’s infrastructure. Glen Island Park is one of the County’s most treasured public spaces, and restoring traffic to the permanent bridge ahead of the busy summer season reflects the tremendous work completed by our County teams, engineers and contractors. This project has always been about balancing preservation, safety and access while ensuring this historic bridge continues serving residents and visitors for generations to come.” Read more: https://lnkd.in/erZ7M5Nd
