road block

I was none too soon, because dead ahead by a thousand feet or so, they were hauling a second road block out.

I whipped the car back, spun it in a seesaw, and took off back towards the first road block.

The highway had obviously been patrolled against a possible ambush or road block.

At one time the road became jammed, and we had visions of staying all night in the midst of a road block.
