DPW is proposing to replace the existing bridge on Barton Road over Miners Ravine. The project is being completed under the Federal Highway Bridge Program (HBP). The project will replace the existing bridge, which is deteriorating and does not meet current design standards. The replacement bridge and improved approaches will bring this bridge into compliance with current structural, geometric, and hydraulic guidelines.
