The southern exit of the circle provides access to Interstate 95 north and south, although only northbound I-95 traffic enters here.

Traffic from southbound I-95 also enters the circle here after navigating a circuitous series of ramps from exit 5.

Drivers leaving the circle to join I-95 can head south towards Massachusetts or north to Maine.

The portion of the Bypass south from the circle leads to US 1 and the seacoast region.

US 4 travels west toward Concord, while the Spaulding Turnpike and NH 16 link the seacoast with the lakes region and the White Mountains.
