They're doing some major road work here in Michigan and on one of the freeways (I-696), they have it down to 2 lanes each way on one side while they tear up the other side.
That said, they just have 2 narrow lanes & don't have a shoulder or anywhere to pull over IF your van did die on you. Aka you'd be screwed.
I'm not that paranoid, but it did cross my mind when I was cruising thru that 10 mile stretch that there'd be nowhere to go except to stop on the freeway.
