The snow may have melted, but travel troubles continue on D.C.-area roads and highways left scarred with car-crippling potholes. Making matters worse, the erratic winter weather that caused the problem is now obstructing efforts to fix it.
A week into spring and even the District’s ballyhooed street-repair blitz, “Potholepalooza” has twice been postponed because the cold just won’t go away.
“People are very frustrated by it, and I am too because I go through it as well,” D.C. Department of Transportation spokesman Reggie Sanders said.
Mr. Sanders noted that even before the start of the sixth annual Potholepalooza workers have been busily patching cratered city streets. About 16,000 holes were filled prior to the first day of spring on March 20.
But the start of the 30-day effort — during which road crews work to fill all reported potholes within 48 hours compared to the standard 72-hour response time — had to be delayed from March 20 and again from Tuesday because of fluctuating temperatures that have dropped from above 50 degrees to below freezing in a matter of hours.
Crews need temperatures to stay above 45 degrees consistently so the roads are thawed before conducting repairs. That can be frustrating to commuters who have to dodge the same stretches of pockmarked streets day after day until the weather warms.
“What we try to do is to educate the people about the process and the conditions we’re under, which is different than in years past,” Mr. Sanders said.
The biggest difference is that the District saw 30.3 inches of snow this winter compared to 3.1 inches last winter, according to the National Weather Service.
Maryland State Highway Administration spokesman Charlie Gischlar said the increase in the amount of potholes is directly related to the increase in precipitation.
“The pothole is formed by what we call, the ‘freeze-thaw cycle,’ ” he said.
As temperatures drop and rise, often between night and day, the roads contract and expand, creating small cracks. Water seeps into those cracks, accumulating into sizable pockets under the pavement. The growing mound of ice lifts the road a bit, and passing vehicles agitate the asphalt. Once the ice under the pavement melts, the section of road will easily collapse, creating a pothole.
Because potholes get bigger quickly, city officials rely on motorists to report them immediately, before they have a chance to grow and inflict more severe damage on vehicles.
Mr. Gischlar said road workers are constantly filling potholes on highways — sometimes hundreds per day. Usually they keep to a Monday-Friday schedule, but they have had to work on Saturdays to keep up with the demand, especially for the larger potholes.
“It’s just bad this year. There’s a lot,” he said.
With regard to the potholes, this is “one of the worst years we’ve seen since 2009,” said John B. Townsend II, AAA mid-Atlantic spokesman, referring to the historically severe winter that saw 56 inches of snow dumped on the D.C. area.
