PHOTOS: Wooden lock gates go up in C&O Canal restoration project

WASHINGTON — The southernmost portion of the historic C&O Canal is a step closer to realizing its former glory in D.C.

On Thursday, big wooden gates that eventually will manage water flow between locks 3 and 4 in Georgetown were added. Restoration of the nearly 190-year-old stone-lined ditch involved it being meticulously deconstructed and reassembled.

“Every stone that was in the lock, they were all labeled, given a number,” park ranger Brendan Wilson said. “Then, we went through and surveyed them, determined which stones we would keep, which stones needed to be replaced.”

Replacement stones came from the same place the original blocks were mined. The quarry about 40 miles away in Virginia was also used for stone to build the White House.

These wooden beams, known as miter sill, are part of the lock gates closing mechanism. A miter sill is the raised part of the bed of a canal lock against which the parts of the gates abut when closing.

Biking the C&O Canal National Historic Park from end to end is on Nat Welch's bucket list. Welch and a friend have come to D.C. from Concord, Massachusetts, to begin the ride, but can't start at mile zero because of the restoration project underway in Georgetown.

The Georgetown reconstruction project is part of a larger plan. The National Park Service is partnering with the nonprofit Georgetown Heritage to revitalize a mile-long stretch of the C&O Canal through Georgetown.

The targeted area is between the canal’s mile marker zero, which is where Rock Creek meets the Potomac River near Thompson’s Boat House. It stretches along the canal to the remains of the Potomac aqueduct, just north of Key Bridge.

The idea for the multiyear plan is to create pockets of places for different activities, such as sitting quietly in a natural area to watch a nesting great blue heron.

“In another section of the park, it’s going to be more active, and that’s where the boat will be operating right here in locks 3 and 4, where school kids will come and ride the boat on a field trip, where tourists can come and learn a little more about the area,” said Maggie Downing, director of programs and partnerships for Georgetown Heritage.

“And then, in other places, it’ll be more focused on recreation, where you can put a kayak on the canal and go paddling,” Downing said.

The restoration project is expected to wrap up late this year or early in 2019. Sometime in 2019, water will be brought back into the canal. Also in 2019, boats might return to the canal in Georgetown to be pulled along like days of old under the power of mules.

The C&O Canal National Historic Park extends between D.C. and Cumberland, Maryland.
