Interstate-393 ramp from Route 106 set to close for summer

If you’re heading to the Seacoast from Sheep Davis Road this summer, be ready for a circuitous beginning to your trip.

The on-ramp heading east on Interstate-393 from Route 106 will close on Tuesday and stay closed for about six weeks as part of bridge work on the interstate.

Instead of using that ramp, drivers will have to get onto Route 9, Loudon Road, and go east for a little over a half mile until it merges with I-393 eastbound.

The confusing part for drivers heading out of Concord on Route 106 is that the intersection with Route 9 comes before the closed ramp. By the time you get to the ramp and see that it is closed, you will have missed the alternative.

The construction will be taking place on two bridges that are east of the on-ramp. They carry I-393 over Horse Corner Road and then over the Soucook River at Concord’s border with Pembroke.

I-393 will not be closed to through traffic on those bridges, though lanes may be squeezed. No other exits will be affected. 

The eastern on-ramp from Route 106 is closed due to problems from vehicles merging into a work zone, said Bill Boynton, spokesman for the New Hampshire Department of Transportation.

Weaver Brothers Construction of Bow is the prime contractor of the $10.6 million project, which is set to be done by October.

Drivers on I-393 have faced backups and squeezes between Exits 2 and 3 for the past few months because of deck work on the bridge taking I-393 over Plymouth Street.
