 Work actually as you head south of Shirlington down towards King Street. Left and center lanes are going to be tied up overnight. You get by single file to the right. Kind of busy through there. Not anything compared, though, to what the lanes of 95 look like in both directions through Dumfries. Construction both ways near 234 and the Triangle Interchange have you down to just one lane of traffic getting by each way. Slow for over a mile each way with just one lane getting by to the left in each direction on that stretch of I-95.
