Chesapeake and Ohio Canal at the site of the Broad Run Trunk Aqueduct, Montgomery County Maryland.
This is a unique spot on the C&O, in that trunk aqueducts were rare.
This was originally built as a double culvert, listed as culvert 44, and the only two span culvert on the entire canal.
The original double culvert was washed out during a flood in 1846, and was hurriedly replaced with a wooden trunk structure. A permanent trunk aqueduct replaced the temporary one in 1856.
All of the wooden timbers that supported this Aqueduct are gone today, and a pedestrian bridge has been erected where the tow path was.
Historic image of the Broad Run Trunk Aqueduct on the Chesapeake and Ohio Canal, from the Library of Congress, Prince and Photographs Division.
This location in Montgomery County, Maryland was once the only double culvert on the entire Canal, but it washed out in a flood in 1846. It was replaced by a temporary wooden trunk structure, and a permanent one was installed in 1856.
Wouldn't trunk aqueducts were relatively common on most canals in the Mid-Atlantic, but the C&O used only stone arches with the exception of this one.
The historic photo was taken sometime after the 1924 abandonment when some of the wooden superstructure was still in place.
Chesapeake and Ohio Canal Lock 25, Edwards Ferry, Montgomery County Maryland.
The site is named for Edwards Ferry which operated across the Potomac River just below the lock from 1791 to 1836.
The lock here was built in 1830, and it was extended in 1881-82 with rock and wooden cribbing on the lower end, to allow for the passage of two boats through the lock at once. This was the first lock to be given this treatment and little exists of that extension today.
The one and a half story brick lockhouse still stands on the Towpath side, and can be rented through the Canal Trusts Canal Quarters program.
Ruins beyond the lockhouse or that of the canal store, which were stabilized by National Park Service. The store closed in 1906.
The ferry stopped operating in 1915.
Benjamin Edwards began the ferry in 1791. He certainly was not the last lockkeeper.
The last lockkeeper was Marion Beall.
