Lock 33 Tunnel - Knoxville, MD - Canal Tunnels on Waymarking.com

Taken from the NRHP nomination form, "8 1 lift. The con tract for construction of the lock was given to James O'Brien in the spring of 1832. Apparently not much work was done and the contract was relet to Littlejohn, Thompson and Company, who completed the lock in the fall of 1833. The site is a narrow shelf of rocky land that is restricted by a nearly vertical rock bluff. This northern bank of the Potomac across from Harpers Ferry, accommodates the canal, the railroad, a roadway, and the various service building required for the several means of transportation, in a very limited space. During the 1800 life of the canal it became a transportation hub with warehouses and a tavern. Of the building, only the ruins of the tavern remain. Most of the stone for the lock is flintstone from a not too distant Virginia quarry. The lock itself is of standard dimensions but the approach, requiring high random laid stone walls on each side of the canal, is unusual. The walls of the main portion of the lock are mainly intact, but there is bulging in the towpath wall, and some stones are out on both sides. The lock pockets, both up and down canal, extensions, and wingwalls are lacking several of their upper courses and in much disrepair. Some gate hardware remains, although of a later day replacement type rather than original."
