You’d think figuring out the gap between two states in the same tiny corner of the country would be simple math. It isn't. Not really. If you ask a GPS "how far is Maine from Connecticut," it’ll spit out a number like 150 miles. But anyone who has actually sat behind the wheel on a Friday afternoon in July knows that "miles" is a liar's metric in New England.
The distance is a moving target. It depends entirely on whether you’re starting in a coastal town like Greenwich or a northern city like Hartford, and whether you’re aiming for the sandy beaches of York or the deep, rugged woods of Aroostook County.
Honestly, the "how far" part is often less about the odometer and more about the gauntlet of Massachusetts traffic you have to survive to get there.
The Raw Numbers: Distance and Drive Times
Let's look at the literal gap first. If you’re measuring from the closest possible points—the northeast corner of Connecticut (near Thompson) to the southwest tip of Maine (Kittery)—you’re looking at about 95 to 100 miles.
That sounds like a breeze. It’s not.
Most people aren't traveling from border-point to border-point. You’re likely going from a hub to a destination. Here is how the road mileage actually stacks up for common routes:
- Hartford to Portland: This is the standard "weekend getaway" route. It’s roughly 180 to 190 miles. In a perfect world with no state troopers and no roadwork, you’re there in about 2 hours and 45 minutes. In reality? Budget 3.5 hours.
- Stamford to Acadia National Park: Now we’re talking. This is a trek. You’re looking at roughly 360 miles. You’ll be in the car for at least 6 hours, likely 7 if you stop for a decent lobster roll in Wiscasset.
- New Haven to Bangor: About 275 miles. You're basically bisecting the region.
The state of Maine is massive—it’s actually larger than the other five New England states combined. So, once you cross that bridge over the Piscataqua River from New Hampshire into Kittery, you might feel like you’ve "arrived," but if you’re headed to the Canadian border, you’ve still got another 5 hours of driving ahead of you.
Maine is deep.
The Massachusetts Factor (Why It Takes So Long)
You can't get from Connecticut to Maine without going through Massachusetts. Well, unless you fly, but we'll get to that.

The distance is psychological.
To get north, you generally have to navigate the I-95 corridor or the I-84/I-90/I-495 shuffle. If you hit the Hartford-to-Worcester stretch at 4:00 PM on a weekday, the 150 miles to the Maine border will feel like 500. Then there’s the "Pike" (I-90). Tolls, aggressive merges, and the inevitable slowdowns around the 128 beltway near Boston.
Most seasoned travelers avoid I-95 through Boston like the plague. They take I-495—the outer loop—which adds a few miles to the trip but usually saves your sanity. If you're coming from Western CT, taking I-91 North through Massachusetts and then cutting across via Route 2 or I-302 can be prettier, but it's rarely faster.
Beyond the Car: Trains, Planes, and Better Ways
If you hate driving, you've got options, though they require some logistical gymnastics.
The Train (Amtrak)
There is no direct "Connecticut to Maine" train. It’s a bit of a bummer. You have to take the Northeast Regional or Acela from a station like Bridgeport or New Haven into Boston South Station. From there, you have to transfer to Boston North Station to catch the Amtrak Downeaster, which runs up to Brunswick, Maine.
Pro tip: The transfer between South and North Station isn't a simple platform hop. You’ve gotta take the "T" (the subway), a taxi, or walk about 1.2 miles.
Flying
Believe it or not, this is becoming a thing. Avelo Airlines has been running flights from Tweed-New Haven (HVN) to Portland (PWM). The flight itself is barely 45 minutes. By the time the flight attendant finishes the safety demo, you’re basically descending over the Casco Bay. If you can snag a $50 ticket, it beats the gas and tolls on I-95 every single time.
The Ferry?
Don't be fooled by the map. While there are plenty of ferries in Connecticut (like the Cross Sound Ferry to Long Island) and plenty in Maine (serving the islands), there is no ferry that connects the two states directly. You're stuck on the asphalt or in the air.
Timing Your Trip Like a Local
If you want the "short" version of the distance, you have to pick your window.
Tuesday at 10:00 AM? You’ll fly.
Friday at 3:00 PM? You’re doomed.
New Englanders know that "The Maine Turnpikes" (I-95) gets absolutely choked during the summer. We call it "The Great Northward Migration." If you’re heading up for a weekend, leave Connecticut on Thursday night or before 6:00 AM on Friday. If you wait until noon, that 180-mile drive from Hartford to Portland will easily turn into a five-hour ordeal.
Practical Insights for the Road
So, how far is it? Technically, it's a three-hour drive. Practically, it's a half-day commitment.
If you’re planning this trip, don't just look at the mileage. Look at the I-495/I-95 junction in Lawrence/Lowell on a map before you leave. That is the true gatekeeper of your travel time.
Also, keep some change or an E-ZPass handy. You'll hit tolls in Massachusetts (on the Pike) and the Maine Turnpike immediately upon entry.
Your Next Steps:
- Check the Avelo Airlines schedule from New Haven if you’re traveling solo—it might be cheaper than gas.
- Download the EasyPark or Maine TurnPike apps to keep an eye on real-time toll traffic.
- If driving, aim to pass through Worcester and the Boston outer loop before 2:00 PM or after 7:00 PM to avoid the worst of the "bridge-and-tunnel" congestion.
Maine is a world away in terms of vibe—quiet, rugged, and pine-scented—but physically, it’s just a long afternoon's drive from the Connecticut suburbs. Just don't forget to fill up your tank before you hit the Maine border; gas prices tend to creep up once you cross the bridge.
