Traffic Shift and Temporary Ramp Closure at Exit 20 on I-89 in Lebanon Rescheduled

NOTE - this work has been rescheduled due to the weather forecast.

The New Hampshire Department of Transportation (NHDOT) will shift the existing I-89 southbound lanes in Vermont onto the newly completed median bridge over the Connecticut river.  The shift is scheduled to be completed over night, Sunday, September 17, 2023.   During this work it will be necessary to temporarily close the I-89 Exit 20 southbound off-ramp to Route 12A.  This closure will start at the same time as the traffic shift of I-89 southbound.  

The Exit 20 ramp construction is anticipated to last four days while the necessary drainage and road reconstruction work is completed. The ramp is scheduled to reopen by approximately 6:00 pm on Thursday, September 21, 2023. The work schedule is weather dependent, and the start date is subject to change. A detour utilizing message boards and temporary construction signs will direct traffic to use I-89 southbound Exit 19 to reverse directions to I-89 northbound where they can use the Exit 20 northbound off-ramp to Route 12A.  Motorists may encounter delays between the I-89 southbound to I-91 southbound off ramp and Exit 19 in Lebanon during the ramp construction.  

Motorists should remain alert while traveling through the construction zone and obey all posted signs. Motorists are also encouraged to sign up for free, real-time construction and traffic related messages (text or email) from https://newengland511.org/.    

R.S. Audley of Bow, NH is the prime contractor for this $43 million dollar project which is scheduled to be completed in September 2025.
