A vehicle collided with a loaded cement mixer truck in Northeast Washington on Tuesday, sending one person in critical condition to the hospital, according to Pete Piringer, spokesman for D.C. Fire/EMS.

Piringer said emergency officials responded to the accident on North Capitol Street just south of Harewood Road just before 2 p.m. North Capitol Street is closed while D.C. police investigate, Piringer said.

According to Piringer, witnesses said the vehicle was headed northrbound on North Capitol Street when it crossed the median and collided head-on with the cement truck. The crash caused “extreme and major damage” to the vehicle and serious injuries to the vehicle’s driver, Piringer said. No other injuries were reported, he said.

Drivers should expect heavy delays in the vicinity of the accident and on surrounding streets, Piringer said.
