Overnight & Daytime Work Includes Temporary Ramp Closures, Paving, and Bridge Preservation; Drivers Should Plan Ahead and Seek Alternate Routes to Avoid Delays

(August 9, 2018) – Summer highway construction continues statewide as the Maryland Department of Transportation State Highway Administration (MDOT SHA) makes improvements along State-maintained routes. In Montgomery County, construction crews are continuing work on several projects – and are preparing to begin work along three heavily-traveled corridors: I-270, I-495 (Capital Beltway) and MD 97 (Georgia Avenue). Permitted work includes temporary lane and ramp closures overnight to avoid peak travel times.

Construction and maintenance work is scheduled at the following locations:

Ramp Resurfacing at the I-270 / Montrose Road Interchange:

Starting at 9 p.m. tonight, MDOT SHA crews will begin a project to repair the pavement and shoulders at theI-270/Montrose Road interchange in Rockville. The first temporary ramp closure is the eastbound Montrose Road ramp to northbound I-270. Motorists can expect nightly ramp closures and detours between 9 p.m. and 5 a.m. Sunday nights through Friday mornings until early fall. Motorists may use MD 355 (Frederick Road) as an alternate route. Remaining temporary ramp closures include: northbound I-270 ramp to westbound Montrose Road; southbound I-270 ramp to eastbound Montrose Road; and southbound I-270 ramp to westbound Montrose Road. MDOT SHA’s contractor is Francis O. Day Construction, Inc. of Rockville.

While MDOT SHA and its transportation partners work hard to maintain safe traffic mobility in work zones, each driver needs to actively modify his or her driving style to help prevent crashes. Stay alert and look for reduced speed limits, narrow driving lanes and highway workers. Slow down and don’t follow too closely. Work Zone Safety is in Your Hands.
