The New Hampshire Department of Transportation (NHDOT) announces an upcoming planned detour for road work on US Route 4 at Exit 6 of the Spaulding Turnpike in Dover.

Beginning at approximately 8:00 pm on the evening of Friday, November 17, eastbound and westbound Route 4 traffic seeking to access the Spaulding Turnpike southbound will be detoured onto Boston Harbor Road at the intersection of Route 4/Boston Harbor Rd./Spur Rd. Motorists will follow the detour approximately one-quarter mile along Boston Harbor Road to a temporary access ramp near the Department of Motor Vehicles (DMV) that will lead them back onto the Spaulding Turnpike southbound. Traffic control devices, message boards, and uniformed officers will be in place to help direct motorists through the detour area.

Once the detour has been initiated, contractors will work continuously to complete the construction of new access ramps that will bring eastbound and westbound Route 4 traffic onto a new Exit 6 southbound on-ramp. The detour is scheduled to be in place from 8:00 pm Friday (11/17) until 8:00 pm on Sunday (11/19), but will be removed from service as soon as the new Exit 6 southbound on-ramp is completed.

The weekend of November 17-19 was chosen for the detour specifically to avoid the high traffic volumes experienced during the work week and upcoming holiday weekends.

This project involves the widening of the Spaulding Turnpike, from the Woodbury Avenue interchange 3.2 miles north to a point 3,000 feet past the Dover Toll Plaza. It will create eight lanes between Exit 3 and Exit 6 on the Spaulding Turnpike, and will provide the final roadway match to the new Little Bay Bridges. Severino Trucking Company is the general contractor for the $67 million project, which is scheduled to be completed in October 2020.
