TRAFFIC ALERT:

The construction of the new Interstate 89 (I-89) Exit 17 northbound ramps will require nighttime closures, starting Sunday, May 4. Traffic will be maintained via an off-site detour at the Exit 18 interchange in Milton during these closures. The work is scheduled for two weeks: from Sunday, May 4, at 7 p.m. to Friday, May 9, at 6 a.m., and from Sunday, May 11, at 7 p.m. to Friday, May 16, at 6 a.m. The Exit 17 northbound off-ramp will be closed to traffic between 7 p.m. and 6 a.m. each night, with periodic closures of the Exit 17 northbound on-ramp between May 11 and May 16. During the off-ramp closures, northbound traffic will be directed to exit the interstate at Exit 18, turn right onto U.S. Route 7 (U.S. 7), and travel approximately 9.5 miles south to the Chimney Corner intersection of U.S. Route 2 (U.S. 2) and U.S. 7. During the on-ramp closures, northbound traffic will be detoured to U.S. 7 at the Chimney Corner intersection, travel approximately 9.5 miles north on U.S. 7, and re-enter I-89 at the Exit 18 interchange in Milton. Temporary traffic control signage and portable changeable message boards will be installed along the detour route to guide travelers. The construction schedule is subject to change due to weather and other field variables. Additional notices will be issued in the coming week.

On Monday, August 19, southbound traffic on Interstate 89 exiting at Exit 17 permanently shifted to the new southbound off-ramp located west of the existing off-ramp.
