The New Hampshire Department of Transportation (NHDOT) will conduct system maintenance on the All Electronic Tolling (AET) lanes of the Spaulding Turnpike in Dover on Tuesday, June 16, 2026, from 6:30 a.m. to 3:00 p.m.

To accommodate this work, there will be alternating lane closures, with northbound lane closures occurring first, followed by southbound lane closures after the morning commute. Travelers should remain alert while traveling and obey all posted signs.

The closures are necessary to safely perform routine maintenance on the overhead toll equipment. Travelers will be guided by signs and traffic cones during the lane closures.
