Commuters in Montgomery County got a rude awakening Wednesday when large potholes forced the closure of Clara Barton Parkway during the morning rush.

The National Park Service closed both sides the road for emergency patching work between the Glen Echo Turnaround and Chain Bridge at about 4 a.m. The closure was expected to last through the day, potentially impacting the evening rush as well.

The emergency work came after complaints from drivers about large potholes and other road damage. Aerial images from NBC4 showed at least one pothole that spanned an entire lane of the road.

Drivers were being encouraged to find alternate routes, including the George Washington Parkway.

Clara Barton Parkway is a 6.8 mile road that is used as a common route into the city for those living in Montgomery County. Typically, traffic is only allowed to travel eastbound toward Washington from 6 a.m. to 10 a.m. and westbound only toward Glen Echo from 2:45 p.m. to 7:15 p.m.
