The Maryland State Highway Administration has said that repairs to fix the sinkhole caused by a failed corrugated drainage pipe in the right lane of I-270 southbound prior to Exit 9 I-370 in Montgomery County could take weeks, according to a report by WJLA. Currently MDOT is assessing the extent of the damage and advising drivers to use MD 355 (Frederick Road) as an alternate route.
The Maryland Department of Transportation State Highway Administration (MDOT SHA) has closed two right lanes on southbound I-270 prior to I-370 in Gaithersburg, Montgomery County to assess a failed corrugated drainage pipe. Crews are currently assessing the extent of the damage and will begin work as soon as possible. Currently, there is no estimated time for lanes to reopen.
MDOT SHA is working with the Montgomery County Department of Transportation to adjust traffic signal timing on MD 355 (Frederick Road), which runs parallel to I-270. Additionally, MDOT SHA is using overhead message signs well in advance of the emergency road repair to alert driver of the situation, including both directions of I-70 in Frederick County.
Approximately 190,000 vehicles on average use this section of I-270 each day, so motorists are strongly encouraged to leave extra commute time, use alternate routes, or utilize mass transit.
