Route 20 Bridge Replacement Project

Route 20 Bridge.JPG Project Overview​​

This is a project to replace the Route 20 bridge over Twenty Mile Creek in North East Township, Erie County.

The bridge is located on Route 20 (Main Street) between the interchange with Interstate 90 and the New York state line. The bridge was closed to traffic in February 2024 following a design analysis of the structure. 

The project will include removal of the existing three-pier bridge with a concreted structure with a single pier. The project will also include guiderail and drainage updates.

Demolition work and new pier construction is expected to occur in 2024. The top of the bridge and minor paving work near the bridge is expected to take place during the 2025 construction season.

Right-of-way impacts and a temporary access road are needed to accommodate demolition and construction.

The bridge was built in 1973. Approximately 2,500 vehicles a day use the Route 20 bridge, on average. ​​

Traffic Impacts​

The existing detour will remain during all phases of construction and is expected to be in place until early fall 2025. The current 8.5-mile detour route is posted using I-90 and Shortman Road in New York state.

Gulf Road (Route 1017) will also be closed at the intersection with Route 20 during construction with a required 2.4-mile detour using Remington Road and Archer Road. The short portion (approx. 1000 feet) of Gay Road between Route 20 and Stinson Road will also be closed during the construction. Traffic will continue on Stinson Road to Route 20.
