East Coast Road Trip: Boston to Washington, DC in 7 Days

Get an E-ZPass before you leave.One transponder works on every toll road on this route, from Massachusetts to Maryland. Several crossings are now cashless, and toll-by-mail rates run noticeably higher, with rental-company processing fees stacked on top if you use a rental car's plate. The biggest charges are the New Jersey Turnpike, the Delaware Memorial Bridge, the I-95 toll in northern Delaware and Baltimore's Fort McHenry Tunnel. A few crossings only charge in one direction, which works in your favor heading south. Our toll roads and E-ZPass guide explains how transponders work with rentals.

The one-way fee is the hidden cost. Picking up in Boston and dropping in DC can add hundreds of dollars to a rental, and it varies wildly by company. You have two alternatives. Drive the loop back north (it makes this a two-week trip), or drop the car in DC and ride Amtrak home. The Northeast Corridor runs the whole route, so the train back to Boston takes roughly 7–8 hours on a Northeast Regional and less on Acela, with no traffic and no tolls. Compare the drop fee with a one-way train ticket; the train often wins.

Timing. The best months are May–June and September–October: mild weather for walking cities, open Newport mansions, and fall color in Connecticut by mid-October. July and August work but bring humidity and beach traffic. Whatever the month, stay off I-95 during weekday rush hours around New York, Philadelphia and Baltimore, roughly 7–9:30am and 4–7pm. Every leg on this plan is short enough to start at 10am and still arrive for lunch.

Mileages are approximate and assume the most direct route between stops; detours in the scenic section below add time. The route totals roughly 500 miles with the Mystic and Merritt Parkway leg, a little more than the 440-mile straight shot.

Newport is the one stop worth two nights if you can spare them. The mansions, the Cliff Walk and a Route 77 loop easily fill a full day, and summer weekends book up early. Midweek rooms are usually far cheaper than Friday and Saturday nights.

Driving into Manhattan is where road trips go to lose money. The Hudson River tunnels charge a toll inbound, and since January 2025 most cars entering Manhattan below 60th Street also pay the Congestion Relief Zone toll (currently $9 at peak with E-ZPass, per the MTA). Then comes parking: overnight garage rates in Midtown commonly top $60 a day, before tax. And every minute you spend in crosstown traffic is a minute you're not seeing the city.

The fix is simple. Book a hotel with on-site parking in Jersey City or Hoboken, drive straight there on Day 3, and don't touch the car until you leave for Philadelphia. The PATH train runs from Hoboken, Exchange Place and Journal Square into Lower Manhattan and along Sixth Avenue to 33rd Street in about 10–20 minutes, and it runs around the clock. Hotel rates on the Jersey side are often lower than comparable Manhattan rooms, and many come with a skyline view you can't get from Manhattan itself.

Coming off the Merritt Parkway, you can reach New Jersey without entering Manhattan: follow the Hutchinson River Parkway and I-95 to the George Washington Bridge, which only charges a toll in the New York-bound direction, then drop south to Jersey City. If you'd like more time around New York, our Hudson Valley and Catskills road trip is the easiest add-on from the same New Jersey base.

I-95 is fast, but it isn't the trip. These four detours add the scenery the interstate skips. Extra times are rough estimates against the direct I-95 route and assume light traffic.

Philadelphia rewards a guide more than most cities on this route. The historic district is compact but dense with stories, and a two-hour walking tour covers Independence Hall, Elfreth's Alley and Washington Square in context.

Park once. DC is built for walking and Metro, not for hunting for parking on the Mall. Many visitors do better staying in Arlington, Virginia, where hotels are often cheaper and frequently include parking, and riding Metro's Blue, Orange or Silver lines to the Smithsonian stop in 10–20 minutes.

The Smithsonian museums on the Mall are free, which changes how you plan: pop into the Air and Space Museum or Natural History for an hour rather than committing a whole day. To go up the Washington Monument, you need a timed ticket. Advance tickets are released on recreation.gov about 30 days out, with a small service fee, and a limited number of same-day tickets go out in the morning, first come, first served.

Go north first. Add three or four days before Boston for coastal Maine or, from late September through mid-October, the foliage loop through Vermont and New Hampshire. Our New England fall road trip lays out the route.

Or keep going south. From DC, Shenandoah National Park is about 70 miles west, and Skyline Drive flows straight into the Blue Ridge Parkway. For beaches instead of mountains, the Outer Banks are a long day's drive southeast. Either way, drop the one-way fee question until you know where the trip ends.

One practical note before you pack: this is a walking trip disguised as a road trip. Boston, Manhattan, Philadelphia and the National Mall are all best on foot, and your shoes will matter more than your car.
