Motorists will want to avoid Connecticut Avenue in Chevy Chase for the rest of the week, when some lanes will be closed for emergency paving, including during peak commuting hours, Maryland highway officials said.
Two northbound lanes are expected to be closed between the District line and East-West Highway during the afternoon rush Wednesday and Thursday, state officials said. Two southbound lanes are expected to be closed during the Friday morning rush.
All six lanes should be paved by Saturday night, officials said.
State officials recommended using Wisconsin Avenue as an alternate route.
The emergency road work is needed because crews doing a major resurfacing project discovered the road base to be severely deteriorated, officials said.
The rush-hour lane closures, which were not previously announced, created severe backups throughout the Chevy Chase area Wednesday morning.
The 1.5-mile section of Connecticut, which is a major commuter route between the District and Montgomery County, has more than 46,000 vehicles daily, state officials said.
