PROJECT LOCATION MAP:

PURPOSE AND NEED:

The Purpose of this project is to preserve and extend the life of the existing pavement and improve ride quality.

Purpose:

The purpose of this project is to improve motorist and non-vehicular bridge users’ safety, restore bridge deck integrity, comply with ADA accessibility requirements and expand access for non-vehicular bridge users, and improve ride quality. 

 

Need:

The steel baluster railing on the west approach has been damaged by vehicular collision and does not meet current safety standards. The concrete bridge deck exhibits spall and delamination and is an ongoing maintenance issue. The existing steel stairs on the southwest corner that leads pedestrian traffic from the parking lot to the bridge is not ADA compliant and restricts bicycle users from riding on the bridge. The vertical clearance of the truss section of the bridge is lower than 15’-6” and warrants placement of vertical clearance signs. The approach pavement at each end of the bridge exhibit cracks and spalls and do not meet smoothness specifications. This results in rough ride quality and recurrent workload for maintenance crews.

FUNDING:

This project was programmed in the 2018 SHOPP and has been funded with the 20.XX.201.110 Bridge Rehabilitation and Replacement Program.
