Montgomery County traffic islands blow tires, draw protests

New concrete traffic obstacles installed along one clogged Montgomery County road blew out the tires of several cars and have neighbors protesting.

The low concrete barriers that extend into traffic lanes, narrowing Jones Bridge Road near North Chevy Chase Elementary School, were meant to slow speeders and help pedestrians cross a road teeming with thousands of cars traveling to the nearby Walter Reed National Military Medical Center. But some say the cure causes pains of its own.
