LEBANON — The southbound on-ramp to Interstate 89 at Exit 19 is scheduled to be closed on Monday morning to allow for a bridge inspection over the Mascoma River, according to a news release from the New Hampshire Department of Transportation.

The closure is expected to last from about 9 a.m. to 12 p.m., or until the inspection is complete. The date is subject to change depending on the weather.

During the closure, motorists planning to use the Exit 19 southbound on-ramp will be rerouted via a signed detour to the Exit 19 northbound on-ramp and then to Exit 20 to reverse direction to access I-89 southbound.
