Block Island, RI to Lambertville, NJ Road Trip Guide

Block Island, shaped by glacial retreat 12,000 years ago, sits atop a terminal moraine that extends underwater to Long Island. The drive to Lambertville, NJ, crosses the terminal moraine of the Appalachian Highlands onto the Piedmont, ending at the Delaware River's Raritan-Magothy aquifer. This 280-mile route (approximately 4.5 hours of pure highway driving) transitions from salt marsh to inland forest.

The route crosses three distinct physiographic provinces: the Coastal Lowlands of Rhode Island, the New England Upland, and the Piedmont of New Jersey. On Block Island, the Mohegan Bluffs rise 200 feet above the Atlantic, an eroding face of glacial till. The ferry ride offers views of Fishers Island and the coast. As you drive through Connecticut, the topography rises into the Metacomet Ridge, home to the 150-foot Talcott Mountain. In New Jersey, the route passes the Sourland Mountain, an ancient lava intrusion turned hardwood forest.

• Connecticut: Cockaponset State Forest (just off I-95 Exit 8) for a 20-minute boardwalk through Atlantic white cedar swamp.
• New Jersey: Delaware and Raritan Canal State Park – walk the towpath for 2 miles from Lambertville.

Local architecture along the way reflects the region's industrial history. Block Island's Victorian hotels contrast with Connecticut's colonial saltboxes and New Jersey's stone farmhouses. In Lambertville, the 19th-century rowhouses house antiques galleries and art studios.

The journey begins with a mandatory ferry from Block Island to New London, CT (one hour crossing, $60 per vehicle). Once on mainland, the drive uses I-95 South through Connecticut, a corridor notorious for variable traffic. Peak delays occur near New Haven and Bridgeport. The most consistent alternative is I-91 South to Hartford, then I-84 West to Danbury, merging onto I-684 to I-287, bypassing New York City. This adds 15 minutes but reduces traffic risk.

• Best fuel stops: Exit 16 on I-95 (Mobil, $3.85/gal) in Connecticut; Exit 30 on I-287 (Wawa, $3.50/gal) in New Jersey.
• Tolls: I-95 in Connecticut has tolls ($1.50 each at three plazas), and New Jersey's I-287 is toll-free until the Garden State Parkway. Have exact change or E-ZPass.
• Road quality: Connecticut sections are concrete with frequent expansion joints; New Jersey's asphalt is smoother but pothole-prone after winter.
• Rest stops: Three major rest areas: two in Connecticut on I-95 (at Milford and Darien) with Starbucks and restrooms, and one on I-78 near Phillipsburg, NJ with bathrooms and vending.
