LEBANON — The I-89 Exit 19 northbound off-ramp will be temporarily closed starting Monday night, to allow for the final phase of rehabilitation of the I-89 northbound bridge over the Mascoma River, according to a news release from the New Hampshire Department of Transportation.
Depending on the weather, the start date could be delayed a week. Construction is anticipated to last eight to 10 weeks while all of the necessary work on the bridge is completed.
A detour utilizing message boards and temporary construction signs will direct traffic to use I-89 northbound Exit 20 to reverse directions to I-89 southbound where they can use the Exit 19 southbound off-ramp.
