C&O Canal aqueducts are "water bridges" that carry canal boats over creeks and rivers that flow into the Potomac River. Built from 1833 to 1835, the Conococheague Aqueduct is the fifth of eleven such "works of art" on the canal. It consists of three equal 60' arch spans extending 196' between abutments.
In August 1863, Confederate soldiers damaged the Conococheague Aqueduct in an effort to stop the canal's transportation of coal to Georgetown where it was used by the Union. Repairs took four days and the canal returned to operation. In April 1920, a canal boat broke through the upstream wall of the aqueduct, falling into the creek below. This shut down the canal for over four months. Repaired with a timber wall, this version of the aqueduct functioned until two 1924 floods closed the canal for good.
In 2019, the NPS completed restoration of the Conococheague Aqueduct, reopening this exciting feature on the C&O Canal. The restored Conococheague Aqueduct provides a watered section of the canal to allow for canal boat operations and other public uses between Lock 44 and approximately 450 feet upstream of the existing aqueduct (approx. 0.70 miles). The $10.2 million project took two years to complete, and was funded through federal, state, local and private dollars including national park entrance fees and Maryland's Transportation Alternatives and Bikeways programs.
Williamsport is now the only place in North America where visitors can view a variety of canal features in one place, including an operational lift lock and refurbished lockhouse, a railroad lift bridge, a canal turning basin and warehouse, and now a watered aqueduct.

Frequently Asked Questions
How long did the project take to complete?
The project began August of 2017 and was completed August 2019.
What did the project include?
The project included constructing cofferdams within Conococheague Creek and rebuilding the aqueduct piers; rebuilding and lining the aqueduct prism so that it is safe, sustainable, and watertight; repairs to the stone work; installation of a period-appropriate guardrail; clearing the canal prism upstream including constructing a berm; and removal of the existing berm on the downstream side so that entire stretch could be re-watered.
How does this project benefit park visitors?
Completion of this project provides park visitors an opportunity to experience a watered transportation canal aqueduct. The project also restores a significant historic resource and provides unique opportunities for visitors.
How can I access the towpath at the Williamsport Visitor Center?
Pedestrians and cyclists are able to cross the canal at the historic railroad lift bridge (adjacent to Rt. 11). Parking is still available by the Cushwa Warehouse.
What is the railroad lift bridge?
Originally used to allow trains to cross the canal, visitors are now able to cross the bridge on a newly constructed stairway, which includes a low bike rail. (This is a great spot to get a view of the canal and aqueduct!).
Where can I find accessible parking near the towpath?
Parking is also available close to the towpath at Lockhouse 44 parking lot and from the Bollman Bridge at River Bottom Park. These are the best access points for visitors with bike trailers, strollers, or wheelchairs. Dam 5 is the next closest location along the towpath that also has parking.
Who can I contact if I have further questions regarding the restoration?
