Screen Shot 2017 09 27 At 2.11.45 Pm

Alert -- the trail is temporarily detoured in McKeesport, Pa. so railroad and emergency vehicles can address a train derailment.  

 Please take Lysle Boulevard from Water Street to Coursin Street (at the Eat n Park restaurant), then ride across Coursin Street to pick up the trail at Locust Street. Watch for traffic on this on-road detour. 

 Thank you, McKeesport Trail Commission, for the alert.

SEP 22 2017 | Slight detour at McKeesport section of the Great Allegheny Passage

As reported by our trail group partner, Steel Valley Trail Council:  It will be clearly marked and safe for all to pass.

Contractors will be cutting two curb cuts for driveways on Locust Street, one in the cul-de-sac section near the end of the fence, and one closer to the railroad crossing (see the red arrows on the map below). Once they've excavated, created the forms and poured the concrete, it will need about another week of curing before bikes can ride it again. Trail users will be able to use Locust Street, a few feet from the trail, as the detour.


This is just before or after trail users cross the Riverton Bridge at mile marker 133.


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.

AUG 8 2017 | Detour in McKeesport mm 131.5) Train blocking road crossing and #GAPtrail

From our Steel Valley Trail Council friends and volunteers:

 The rail crossing at Locust Street in McKeesport is closed while it is being rebuilt, as you'll see in the attached photo. The CSX worker I talked with said that the rails had been sinking in the mud at that crossing and that "the crossing should reopen at the end of the week."Image1

Use simple common sense: trail users traveling east, go 1 block to your LEFT to Coursin Street flyover bridge, cross over the train tracks, make RIGHT on Lyle Blvd and continue on your way.

or vice versa coming traveling west, follow Lyle Blvd to Coursin Street, make a LEFT up and over Courisn flyover bridge.  

Thanks for your patience and cooperation.  Enjoy the trails!

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.
