The Federal Highway Administration is working to correct road settlement on the Baltimore-Washington Parkway in Prince George's County.

One lane on the northbound and southbound sides of the parkway at the Route 197 interchange is likely to be closed this week. Closures will be from 9:30 a.m. to 3:30 p.m. southbound through Friday; 8:30 a.m. to 2:30 p.m. northbound through Friday; and 6 a.m. to 4 p.m. in both directions Saturday.

Delays should be expected southbound below Route 198 and northbound above the Capital Beltway. Motorists are advised to tune in to WTOP 1500.

The work is expected to continue for five weeks. Information: 301-474-3112.
