Montgomery County drivers who use the Intercounty Connector (MD 200) could be affected by this weekend's closure as Maryland Transit Authority (MDTA) upgrades hardware and software of all toll facilities. Beginning 9 p.m. Friday, Feb. 21 through 5 a.m. Monday, Feb. 24 westbound traffic will be detoured at Layhill Road to Georgia Avenue. Those traveling between I-370 and I-95 may consider taking I-495. Detours will continue into April to ensure the safety of workers and motorists. Stay updated at twitter.com/MDOTNews.
