Exit 49 off the Long Island Expressway in both directions will be closed nightly through Friday from 10 p.m. to 3 a.m. so work can be performed on the aging Pinelawn Road bridge, according to the New York State Department of Transportation.

Motorists are being detoured to the LIE service roads.

These closures are due to repair work being on the bridge as part of a $5.5 million rehabilitation project.
