Most lanes of the Capital Beltway’s inner loop have been opened to traffic after an early morning accident.
The right lane remains blocked between I-270 and Connecticut Avenue, but all other lanes are getting by.
The accident involved three vehicles and happened about 5:18 a.m. At one point, all but one lane was closed to traffic as police investigated and clean-up crews cleared the road of fuel and debris.
