The speed limit on the Intercounty Connector (MD-200) will officially increase from 55 mph to 60 mph this weekend.
The highway runs between I-270 and I-95 through Montgomery and Prince George's counties.
As the old signs come down, crews are replacing them with slightly faster 60 mph signs.
The move comes after the Maryland Transportation Authority completed an engineering study and analysis of crashes. Both indicated a speed limit of 60 mph would be safe.
In January, two dozen Maryland lawmakers pushed for the speed limit on state highways to increase to 70 mph. While some nearby residents have expressed concerns about additional road noise, drivers were all for the faster pace.
"I think it's fine to make it 60 mph," says Michael Zazanis of Darnestown. "It's not heavily traveled. I think it's a safe speed based on the roads design. Sixty is probably good enough."
"I think five is fine," says Adam Fine of Gaithersburg. "Five is probably the perfect amount to raise the speed limit."
"I would take 65 over 60 mph. We are happy for the ICC. We could speed it up a little more," says Delion Campbell, also of Gaithersburg.
