The state will be raising the speed limit from 55 mph to 60 mph next month on the Intercounty Connector, Maryland's first all-electronic toll road.

The decision Monday by the Maryland Transportation Authority came after more than six months of study of engineering data and the 20 single-vehicle crashes that occurred in the highway's first year of operation. It also renders moot a bill filed last month by two Montgomery County lawmakers to increase the speed.

State officials estimate the higher speed will shave 90 seconds off a trip from Interstate 270 in Gaithersburg to Interstate 95 in Laurel. Harold Bartlett, MdTA's executive director, said 60 mph is "safe and justifiable."

But just to be on the safe side, crews will be installing curve warning signs on the 18-mile road, also known as MD 200, between now and the end of March.
