UPDATE: All of U Street reopened to traffic around 3:50 p.m., according to DDOT.
UPDATE: U Street reopened between Seventh and 14th streets around 11:30 a.m. The roadway between 14th and 16th remains closed to all traffic except buses, as of 11:50 a.m, the DDOT said.
Washington got its own oil spill as an oozing substance made U Street too slippery for traffic.
A truck traveling down U Street early Wednesday morning sprung a leak of what the District Department of Transportation calls “grease” and other reports call “cooking oil.”
“Looks like it was probably grease leaking from a trash truck, but don’t know for sure,” the DDOT tweeted.
Department of Public Works spokesman Linda Grant said the truck was a vehicle that collects cooking oil from restaurants.
Officials closed U Street from Ninth to 16th streets while a sand truck worked to soak up the spill. 14th street between T and V streets also closed but reopened shortly after 10 a.m.
U Street remained closed at 10:30 a.m.
Officials plan to reopen U Street to traffic but will restrict travel to 10 miles per hour, until street sweepers can clean the road.
