Starting at 8 p.m. tonight, the Maryland Department of Transportation’s State Highway Administration (SHA) will temporarily close three right lanes on northbound I-495 (Capital Beltway) between Exit 39 (MD 190 - River Road) and Exit 38 (MD 191-Bradley Boulevard) in Carderock. The lane closures are necessary for concrete repairs to the underside of the MD 191 bridge over I-495.
SHA will close one lane starting at 8 p.m. and 9 p.m., two lanes at 9 p.m., and three lanes between 11 p.m. and 5 a.m. The lane closures are necessary for the safety of both work crews and drivers. Three left lanes of the six-lane section will remain open for traffic, allowing motorists access to I-495 east and I-270 north once they drive beyond the work zone. All of the work will be completed underneath the bridge; no lanes will be affected on MD 191.
