The primary artery is I-95 South, but savvy travelers use a mix of coastal routes. From Portsmouth, take I-95 to the New Hampshire coast, then cross into Massachusetts via the Tobin Bridge (Route 1). In Connecticut, consider switching to the scenic Merritt Parkway (Route 15) at Milford, which bypasses I-95's traffic around New Haven. After the George Washington Bridge in New York, continue on the New Jersey Turnpike (I-95) to the Delaware Memorial Bridge, then follow Route 1 to Ocean City.

Estimated driving time is 6.5–7.5 hours without stops. However, traffic in the New York metropolitan area can add 1–2 hours. Plan to leave early morning or after 10 AM to avoid rush hour.

• Fuel stops: Gas stations are abundant along interstates, but prices drop near state borders (e.g., Delaware has lower taxes). Fill up before entering New York and New Jersey for savings.
• Tolls: Expect tolls on the New Hampshire Turnpike, Massachusetts Turnpike, Tobin Bridge, Merritt Parkway, New Jersey Turnpike, and Delaware Memorial Bridge. Carry exact change or use E-ZPass.
• Road quality: Generally good, but New Jersey Turnpike has frequent construction. Merritt Parkway is scenic but has narrow lanes and stone bridges – larger RVs may want to avoid.
