Overnight commuters who take the Northern State Parkway should prepare for some road closures.
Beginning Monday, the eastbound lanes between exits 37A and 40 will shut down overnight so crews can repair the Round Swamp Road bridge. The lanes will be shutdown from 11 p.m. - 6 a.m. Sunday through Thursday.
The westbound lanes will be closed beginning May 20. The lanes will be closed from 10 p.m. - 5 a.m. from Sunday to Thursday.
The closures are expected to last about three months.
