The deliberations on how to repair the collapse of the beautiful 1840 stone arch tunnel that carries High Falls Creek under the canal, which has caused the loss of water through UBE (and points south) since March 29th, have been completed.
The scope of the project expanded in July when it was discovered that the repairs to the collapsed portion would not be sufficient, as the remainder of the 175-year-old stone culvert was not structurally sound.
The consultant, Bi-State Construction of Easton, PA., has determined that a metal sleeve can be inserted the whole length of the stone arch culvert, serving as a permanent repair. This allows the project to move forward as a maintenance project, without having to proceed through a time-consuming new permitting/design process. An Erosion and Sedimentation (E&S) plan will need to be submitted for County approval, though. Park Manager Rick Dalton is optimistic about this development, but cautious about announcing a timeline for repair completion until the E&S plan is approved, which will then trigger the review of the newly developed repair plans.
The construction of temporary repairs on the 1840 High Falls Creek arch tunnel which collapsed March 29th have begun, according to Park Superintendent Rick Dalton. The aim of these interim repairs is to provide for filling the canal and reopening the towpath as the longer-term permanent project, which must go through the state design and bidding process, runs it’s course,
Superintendent Dalton describes the work so far:
An access crossing of the canal has been constructed, with the ramp down into the culvert completed. Footers have been formed and concrete has been poured on both sides. A curved steel plate has been ordered to span the breech. When manufactured and delivered it will be placed and secured over the culvert. The area will then be back-filled, the towpath rebuilt and refilling of the canal will be attempted.
DCNR has appropriated funds for the repairs, according to Mr. Dalton. The Friends of the Delaware Canal (http://www.fodc.org/) have provided substantial financial support for this project, as well. Bi State Construction Co., Inc. of Easton, PA will execute the temporary repairs.
The collapse of the beautiful 1840 stone arch tunnel that carries High Falls Creek under the canal, which has caused the loss of water through UBE (and points south) since March 29th, is slated for temporary repairs to get water flowing while the larger and more complicated permanent reconstruction, which must go through the state design and bidding process, runs it’s course.

Work began Tuesday, 5/5 and is slated to take about a month.
The concept is to make a curved metal plate that will be anchored in cement footings to cover the open part of the culvert. It will take 2-4 weeks to fabricate the arched metal plate. Then the canal will be able to run over it, although maybe not at a full volume. The elegant, original stone arches will be preserved.
