 Northbound I-95, that work crew is near the Centerport Parkway. Similar story, just a single lane gets by. Pardon me, it looks like you actually have two right lanes getting by headed northbound past the Centerport Parkway. So just be aware of that one. You are quite slow, but once you're past the Centerport Parkway, it's a straight shot all the way up towards Springfield. In Maryland, a few work crews, if you're headed southbound on 270, for example, you should find the work zone near Falls Road. It looks like they've got the left lane blocked in the locals, right lane blocked in the main lanes.
