Towpath Resurfacing Project
https://www.nps.gov/choh/planyourvisit/towpath-resurfacing-project.htmThe most recent phase of resurfacing stretches from Whites Ferry (Mile 35) to Brunswick (Mile 54). This phase of work was completed as of April 1, 2020. When work is active, visitors may see temporary horseback riding restrictions. Please read more on our Horseback Riding page.
Visitors will now be able to enjoy nearly 56 miles of resurfaced towpath between Swains Lock (Mile 16.5) and Ferry Hill (Mile 73)
The goal of the resurfacing project is threefold:
To maintain the historic integrity and character of the towpath
To maintain the durability of the towpath during high water and flood events
To provide a smooth, level surface for hikers, bikers, and visitors who utilize the towpath on a daily basis
The resurfacing techniques are not catered to one particular usage group, such as runners or bicyclists. Rather, the park is piloting a new resurfacing model to make the towpath as durable as possible for all park users.
What are the resurfaced layers made of?
The towpath is NOT being paved. The base layer of the new towpath surface is crush and run gravel, also known as CR-6. The top layer is stone dust, also known as AASHTO-10. The crush and run layer creates an adequate drainage system, so that heavy rainfall can easily drain off the towpath. The stone dust layer at the top adds a nice, smooth surface.
