LEBANON — A temporary closure of the Exit 20 off-ramp on I-89 southbound has been rescheduled to start on Sunday, Sept. 17, due to anticipated weather conditions this weekend, according to the New Hampshire Department of Transportation, or NHDOT. 

NHDOT announced plans this week to close the southbound Exit 20 ramp — which connects southbound traffic on I-89 to Route 12A — for repairs and drainage improvements.

Workers will close the ramp during the night of Sunday, Sept. 17. The construction work is expected to take four days to complete, according to a press release from Richard Arcand, of NHDOT. 

The ramp is tentatively scheduled to reopen by around 6 p.m. on Thursday, Sept. 21, though the work schedule depends on weather, so the date of work completion may change. 

Motorists seeking to connect to Route 12A will be directed to use Exit 19 to reverse direction onto northbound I-89, so they may use the northbound Exit 20 off-ramp to access Route 12A. 

During ramp construction southbound motorists may encounter delays on 1-89 between the I-91 off-ramp and Exit 19 in Lebanon, Arcand stated. 

Also effective Sunday night, NHDOT plans to shift the existing I-89 southbound lanes in Vermont onto the newly completed median bridge over the Connecticut River. Motorists are urged to stay alert while traveling through the construction zone and obey posted signage. 

NHDOT originally planned the closure to begin on Sunday, Sept. 9 but rescheduled the construction start date due to anticipated rain storms next week.

This portion of the bridge work, which began in May, is part of a five-year, $43.8 million project to rehabilitate and upgrade both spans across the Connecticut River.

The overall project began in 2020 and is scheduled to be completed in September 2025.

Meanwhile the northbound I-91 exit ramp to I-89 south has remained closed since July 16 due to slope instability. According to Andrew Silovich, of NHDOT, repairs to this ramp will begin once the Exit 20 construction work is completed. The repairs to the I-91 off-ramp are expected to take two weeks but may take longer depending on the weather during construction.
