Earlier this week coming back from Arlington, traffic had ground to a near absolute halt. I was in an Uber that was making no progress, so I got out and walked the two miles or so home. It was a beautiful evening for it, on foot. Here are some scenes nearing the Francis Scott Key Bridge, and of the Georgetown canal path just over the other side of the bridge.

It turned out that a tanker had turned over on the Beltway:

Commuters, take heed. Anyone intending to take the Inner Loop of the Capital Beltway today needs to contend with a tanker truck that overturned near the American Legion Bridge around 2 p.m.

While the driver of the truck was not injured in the crash, there was a minor injury from one of the cars, according to Fairfax Fire and Rescue.

Further complicating the response is that the overturned tanker was holding 8,500 gallons of fueland was actively leaking. A total of 100-200 gallons leaked, but Fairfax Fire and Rescue says that the fuel has been “has been contained and does not appear to have made it into the Potomac River.” …

The lanes on the Inner Loop of the Capital Beltway reopened just before 3 a.m. on Friday morning.
