LEBANON — Nighttime paving work will cause temporary closures of the ramps at Exit 19 on Interstate 89 during evenings through Monday.

The state Department of Transportation has already started nighttime milling and repaving of northbound and southbound lanes near the exit.

The work will necessitate temporary closures of the ramps between I-89 and Route 4 in Lebanon. Only one ramp will be closed at a time

To access Route 4, interstate traffic will be detoured to either Exit 18 or Exit 20, where drivers can reverse direction and access the open Exit 19 offramp on the opposite side.
