The replacement bridge will have a clear span length of 28 feet. Concurrent to the replacement of the bridge structure, roadway infrastructure improvements extending approximately 200 feet along each West Main Street approach will include but not limited to full depth pavement reconstruction, cement concrete sidewalks and pedestrian curb ramps, driveway aprons, drainage system improvements, installation of guardrail, signing, pavement markings and related work as directed by the Ayer Department of Public Works. The Contractor shall be responsible for coordination with impacted utility companies for temporary and/or permanent relocations required as part of this project.
