Frequently Asked Questions: Towpath Resurfacing Project

The resurfaced towpath near Edwards Ferry

Will the whole towpath be resurfaced?

Following an engineering study done in 2016 with the assistance of the Allegheny Trail Alliance (ATA), 80 miles of the towpath were identified as urgently in need of rehabilitation. The Park will continue to repair and maintain other sections of the towpath, as needed.

Which sections of the towpath have been identified for rehabilitation?

Phase 1 (to be completed in 2019): Mile 30.8 (Edwards Ferry) to Mile 35.5 (Whites Ferry); Mile 54 (Brunswick Family Campground) to Mile 71.4 (Packhorse Ford)

Phase 2 (to begin in late 2019): Mile 42.2 (Monocacy Aqueduct) to Mile 54 (Brunswick Family Campground)

Phase 3 (planned for 2020): Mile 23 (Seneca Creek Aqueduct) to Mile 30.8 (Edwards Ferry); Mile 35.5 (Whites Ferry) to Mile 39.3 (Lock 26)

Please note that depending on a number of factors, phases may not be completed in the order listed here.

Other sections identified for future comprehensive rehabilitation:

  • Mile 76 (Snyders Landing) to Mile 81 (Taylors Landing)
  • Mile 84.2 (Dam 4) to Mile 85.6 (Guard Lock 4/Big Slackwater)
  • Mile 112.4 (Fort Frederick) to Mile 114.5 (west end of Big Pool)
  • Mile 154.5 (Sorrel Ridge) to Mile 155.8 (Paw Paw Tunnel)
  • Mile 173.4 (Spring Gap) to Mile 18.8 (Gene Mason Sports Complex Rd)

What will the rehabilitation involve?

  • Removal of rocks, tree roots, and other obstacles.
  • Removal of grassy median strip.
  • Grading of towpath to facilitate water runoff.
  • Re-surfacing with the same crushed stone dust on the Great Allegheny Passage (GAP).

What is the benefit of the new crushed stone dust surface?

The current gravel over clay surface, which constitutes the current towpath surface, holds water and is prone to muddiness when wet. Crushed stone dust, particularly on a properly graded surface, does not retain water and hardens with use, making it less likely to erode and rut. It is also easier to maintain over time.

How is the work being funded?

Phase 1: Funded by a grant of $1 million from the state of Maryland’s Transportation Alternatives Program (TAP) and $1.8 million from the National Park Service.

Phase 2: Funded by a TAP grant of $1.25 million and $458,607 from the National Park Service.

Phase 3: The C&O Canal National Historical Park is seeking $1.02 million in TAP funding to be matched by $472,236 from the National Park Service.

How is the C&O Canal Trust supporting the towpath resurfacing project?

The Trust is raising funds to support engineering consulting and other support services, as well as directly supporting resurfacing. It is also spearheading advocacy for ongoing TAP funding.
