Portsmouth Area Insider TipsThe Inside Scoop From Seasoned I-95 Travelers

The Hampton tolls (just south of Portsmouth) are notorious for backups, especially Friday afternoons and Sunday evenings in summer. EZ-Pass lanes move much faster.

The Portsmouth Traffic Circle where I-95 meets the Spaulding Turnpike can be confusing - stay in your lane and commit early.

Beware of Speed Traps. State police actively patrol the short NH stretch, especially northbound. Speed limit drops from 65 to 55 near the tolls.

Gas Up. New Hampshire has no sales tax, so gas is usually cheaper than MA or Maine. Fill up before crossing into Maine if heading north
