The ramp closure at Exit 19 on I-89 in Lebanon will require completely closing the northbound off-ramp for 8-10 weeks. There will be no access at all during this time.
The New Hampshire Department of Transportation (NHDOT) announces the temporary closure of the I-89 Exit 19 northbound off-ramp starting the night of September 26, 2022, to allow for the final phase of rehabilitation of the I-89 northbound bridge over the Mascoma River.
Construction is anticipated to last 8-10 weeks while all of the necessary work on the bridge is completed. The work schedule is weather dependent and the start date could be delayed a week for construction crews and materials. A detour utilizing message boards and temporary construction signs will be put in place directing 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.
Motorists should remain alert while traveling through the construction zone and obey all posted signs.
