Repairs of the partially collapsed storm drain that led to the closure of a Bethesda road last week will keep one lane of the road closed for several months.

According to the Department’s Division of Highway Services, a storm drain culvert under Hillandale Road roadway was found to be degraded last Thursday. That led to the county closing the northbound lane of Hillandale Road between Little Falls Parkway and Willet Parkway.

Montgomery County Police issued an alert on Wednesday saying the repairs will keep the lane closed for “several months.”

The closure cuts off access to the Bethesda Swimming Pool (6300 Little Falls Parkway) and Willet Parkway from the south. Detour signage has been set up to direct drivers to northbound Arlington Road, eastbound Bradley Boulevard and then southbound Hillandale Road.
