The Maryland State Highway Administration’s Charlie Gischlar has told WTOP 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
will take several more weeks, and they are “hoping we can get it open by the Fourth of July holiday, if not sooner.” Drivers are encouraged to use MD 355 (Frederick Road) as an alternate route during this time. According to the report, Montgomery County traffic officials have adjusted signal timing on 355 to help the flow of traffic.
Also on 270, MCDOT said has said that the resurfacing project on I-270 south of MD 109 will continue from 7:00pm-4:00am each night until mid-July 2022 (weather permitting).
