With rapid changes in temperature and various types of liquid and frozen precipitation falling, potholes are beginning to appear with increased frequency around Arlington.

One such pothole, on Lorcom Lane just west of the intersection with Spout Run Parkway, is 3 inches deep at its lowest point. This afternoon it announced itself to passersby with a “thunk” each time an unsuspecting driver rolled over it.

Police radio traffic indicates there are several other significant potholes causing minor traffic problems in other parts of the county. Arlington officials say they’re trying to stay on top of such reports and fill in the pesky potholes as quickly as they can.

“The county has already tried to start our push on pothole work, beginning with two or three full days including work over a weekend,” Arlington Dept. of Environmental Services spokeswoman Robyn Mincher said. “Temperatures in the teens and inclement weather have slowed down this effort. We will devote additional resources to potholes as we can in the next week or two, and then continue filling work through the winter and into spring when many potholes appear.”

Residents who observe potholes in Arlington can report it online directly to county staff.
