Motorists traveling Interstate 30, 440 and 530 will see nighttime lane closures beginning Feb. 15.
Rehabilitation work on signs will take up to two weeks, the state Highway Department said.
The improvements will require single lane closures in both directions on Interstates 30, 440 and 530 in central Arkansas. The lane closures will be in effect from 8 p.m. to 5 a.m. Tuesday through Friday each week, weather permitting. Between the hours of 11 p.m. and 5 a.m., all lanes in a single direction may be closed for periods of up to ten minutes.
