Installation of camera poles on the Interstate 495 on-ramp to Route 213 means closing the ramp overnight Wednesday.
The Massachusetts Department of Transportation said camera pole installation operations will take place along the on-ramp from I-495 south to Route 213 west in Methuen. Work is scheduled to take place from 8 p.m., Wednesday, Sept.1, through 5 a.m., Thursday, Sept. 2.
Traffic heading southbound on I-495 will be detoured first to the next exit, exit 104, then left before heading the opposite way on I-495 northbound, where drivers may access 213 westbound.
Work is weather dependent and subject to change without notice.
