AUG 10 2017 | Paw Paw Tunnel (mm 155.2-155.8) closure extended

Paw Paw Tunnel closed as of today June 2, 2017:

Update: Paw Paw Tunnel is closed as of June 2, 2017. The closure is extended until October 2017.

C&O Canal National Historical Park has closed Paw Paw Tunnel as part of the planned rock scaling project. The park anticipates that the tunnel will remain closed between 100 and 120 days, hopefully re-opening around the end of September.

To provide thru-access for bicyclists during the project, a bypass trail will be available using an old logging road on the berm side of the canal upstream of the tunnel. A temporary “bridge” across the canal prism connects with an abandoned logging road that provides a gentler grade to the top of Tunnel Hill. This temporary by-pass then connects with the existing Tunnel Hill Trail.

Rock scaling is the physical removal of loose rock and unstable surface materials that pose a hazard. The project will enhance visitor safety by reducing the risk of injury from falling rocks.

For more information check the official C&O Canal NHP website.

JUN 30 2017 | Conococheague Aqueduct Restoration Construction & Detour (mm 99.7)

By Linzy French

 Assistant to the Superintendent, C&O Canal National Historical Park

Williamsport, MD – The National Park Service (NPS), Chesapeake and Ohio Canal National Historical Park (C&O Canal) awarded an $8,997,112 contract for the restoration of the Conococheague Aqueduct to Corman Construction, Inc. of Annapolis Junction, MD on June 5, 2017. The next phase of the restoration project for the entire Williamsport interpretive complex will return the Conococheague Aqueduct to its 1920s appearance and create the first watered, operational aqueduct along the C&O Canal since 1924. During construction, visitors will be directed to follow a detour route around the Conococheague Aqueduct located near Williamsport, Maryland between milepost 99.75 - 99.60.

20170620 Conococheague Bypass Plan   

Construction is anticipated to begin in late July 2017 and extend approximately 18 months, weather dependent, until December 2018. During this time visitors will be unable to travel over the aqueduct and through the construction area and will be directed onto a 1.1 mile long detour route around the Conococheague Aqueduct. The upstream end of the detour departs from the towpath near milepost 99.75, travels along Fenton Avenue, an alleyway, state Route 68, and U.S. Route 11 until rejoining the towpath near milepost 99.60 (directly adjacent to the Cushwa Basin). Prior to closure of the towpath, signage will be posted to clearly mark the detour route.

The Conococheague Aqueduct is one of eleven aqueducts on the 184.5 miles of the C&O Canal and is listed on the National Register of Historic Places. Over 97 years ago, in April of 1920, the upstream wall of the Conococheague Aqueduct gave way, crumbling into the creek below. The C&O Canal Company temporarily repaired the aqueduct with a wooden wall, but the canal only operated for three more seasons before being closed in the spring of 1924.

The project will restore the aqueduct to its appearance in the early 1920s, with a new upstream wall designed to appear as the wooden temporary replacement wall. More importantly, the aqueduct will be restored to the condition where it can once again hold water, the first C&O Canal aqueduct to be restored to full operation. When complete, Williamsport, Maryland will be the only place in North America where visitors can ride boats across an aqueduct and through a working canal lock.
