Chesapeake and Ohio Canal approaching the Abner Cloud House, Washington DC.
Abner Cloud was a Quaker from Pennsylvania who took up the Revolutionary cause for America, and was disowned by his family as a result. He settled here and build this house in 1801. Abner died in 1812, and his widow. Susan lived here until her death in 1852.
Cloud operated a mill close by on the original Potowmack Company skirting canal that had been built in the 1790s. The Chesapeake and Ohio Canal took the earlier canal route through this area.

Historic 1865 view of the Chain Bridge, over the Potomac River and Chesapeake and Ohio Canal in Washington, DC, from the Library of Congress collection. Union soldiers are seen patrolling the bridge, as these places would be considered targets.
The site of this bridge was previously a ferry crossing dating back to 1737.
The first bridge to cross the Potomac River at this site was a covered bridge completed in 1797. It collapsed in 1804.
The area is known as the Chain Bridge because a suspended structure from huge chains was completed in 1808. This bridge was swept away in a flood in 1810. It was rebuilt in 1811, and lasted until 1852 when it too was damaged by flooding.
In 1854, a timber truss bridge was constructed at the site, using the Burr Arch plan. This was replaced in 1874 with an eight span Howe truss structure. This bridge collapsed in the 1936 flood and was replaced in 1939 by the steel cantilever girder structure that stands today on the historic 19th century piers.
