Permanent lane closures will remain as configured on Interstate 91
Permanent lane closures will remain as configured on Interstate 91 in both directions just north of Exit 16 during road construction projects. A speed limit reduction to 55 mph is currently in place. Travelers near St. Johnsbury should be advised that the Exit 20 I-91 southbound on ramp continues to remain closed. The signed detour is in place directing traffic to enter I-91 northbound and drive up to Exit 21 to then turn around and safely enter I-91 southbound from that location. In addition, Route 5 northbound under I-91 Bridge 83 South has been reduced to a single lane while the contractor works on the bridge overhead.
