WASHINGTON - An accident on the Inner Loop of the Capital Beltway let traffic trickle by to the left as authorities dealt with a possible fuel spill Monday night.
A tractor-trailer was overturned in the accident, which occurred just before 11 p.m. Monday, say Maryland State Police.
Initially, it blocked the Inner Loop completely before Route 450/Annapolis Road.
By 12:20 a.m., the two left lanes were getting by. The driver has critical injuries, say police.
