I-270/Watkins Mill Road Interchange Steel Beams to be Installed in Montgomery County

Motorists should expect evening lane closures overnight beginning on Sunday, February 3, 2019.

(January 30, 2019) – The Maryland Department of Transportation State Highway Administration (MDOT SHA) is preparing to set structural support beams at the I-270/Watkins Mill Road interchange project in Gaithersburg. The steel beam installation work will begin February 3 and be complete by the beginning of March.

To perform this phase of the $84 million project, motorists will encounter nighttime single, double and triple lane closures, as well as brief, 20-minute total stoppages. MDOT SHA will begin installing the new steel over southbound I-270, then shift to the northbound direction.

Motorists can expect single lane closures beginning at 7 p.m., double lane closures at 9 p.m. and triple lane closures beginning at 11 p.m. with all lanes opening by 5 a.m. each subsequent morning. Additionally, brief total closures will occur between 12 midnight and 5 a.m. The work will take place Sunday nights through Friday mornings.
