Chesapeake and Ohio Canal National Historical Park has closed the pedestrian bridge at Dam 4 Winch House (mile marker 84.6) to all traffic. During a recent inspection, engineers found that the walkway’s supports have wood deterioration due to rot, and the metal hangers for the walkway support beams have been severely corroded. The bridge provides pedestrian access from the parking area off of Dam No. 4 Road, over the historic stone stop-gate and canal to the left abutment of Dam 4. The park and amenities, such as the parking lot at Dam 4, remain open to recreational use.
The National Park Service is evaluating alternatives to restore the structure to reopen the bridge.
Alternative access to this area is available via the towpath, with parking available 1-mile upstream at Big Slackwater Boat Ramp parking area. Check online to see recreational opportunities at each milepost along the
canal. This closure does not affect the towpath or through riders on the towpath.
