Ask people which road takes you across America and most of them will say Route 66. It's a good answer for a pub quiz and the wrong one for this trip. Route 66 never touched New York or San Francisco. If you want to put your car on the Atlantic side and drive until you hit the Pacific at the Golden Gate, the road you're looking for is older and a lot less famous: the Lincoln Highway, and the interstate that more or less replaced it, I-80.
This is how I'd plan that drive - which route to pick, how many days it really takes, what to see on the way, what to do about the rental car, and roughly what the whole thing costs.
First, It's Not Route 66
Route 66 runs from Chicago to Santa Monica, about 2,450 miles through Illinois, Missouri, Kansas, Oklahoma, Texas, New Mexico, Arizona and California. It was created in November 1926, which makes 2026 its hundredth birthday, and it was officially dropped from the US highway system in 1985. What's left today is a patchwork of old alignments, diners and motel signs, and it's a great trip. It just goes to Los Angeles, not San Francisco, and it starts a long way from New York.
You can still fold it into a coast-to-coast drive, and further down I'll show how. But if the plan is literally "New York to San Francisco", the straight line is somewhere else.
The Road That Actually Goes Coast to Coast
In 1913 driving across the United States was something you did to prove a point. There were no numbered highways and barely any paved roads west of the Mississippi. A group led by Carl Fisher, the man behind the Indianapolis Motor Speedway, decided to fix that and marked out the Lincoln Highway: a single route from Times Square in New York to Lincoln Park in San Francisco, about 3,400 miles long. It was dedicated on October 31, 1913, and it's the reason a coast-to-coast drive became something normal people could attempt.
Six years later the US Army sent a convoy of trucks along it to see whether military vehicles could cross the country. It took 62 days. One of the officers on that 1919 convoy was a young Dwight Eisenhower, and he never forgot how bad the roads were. Decades later, as president, he signed the act that created the Interstate Highway System. So in a roundabout way, this one road trip gave America its freeways.
The Lincoln Highway still exists in pieces - mostly as US 30 through Pennsylvania, Ohio, Indiana, Iowa, Nebraska and Wyoming, with red, white and blue "L" markers on poles and old concrete posts in small towns. And Interstate 80 follows its general line almost the whole way, from Teaneck, New Jersey, just across the George Washington Bridge, to the Bay Bridge in San Francisco. That pairing is the backbone of this trip: I-80 when you want to make time, the old highway when you want to see something.
Three Ways to Drive It
There isn't one right route. These are the three I'd actually consider.
- I-80, the direct line - about 2,900 miles through Pennsylvania, Ohio, Indiana, Illinois, Iowa, Nebraska, Wyoming, Utah and Nevada. It's the fastest way and the closest to the original Lincoln Highway. The middle part is flat and long, and that's part of the point: you feel how big the country is.
- I-70 through Colorado and Utah - leave I-80 for I-70 in Pennsylvania or Ohio, go through St. Louis and Kansas City, cross the Rockies west of Denver and Glenwood Canyon, then the red rock country of Utah. It adds a day or two, but the scenery in the west is a different level. I-70 ends in the middle of Utah, so you rejoin I-15 and then US 50 or I-80 for Nevada.
- Route 66 plus the coast - drive New York to Chicago first (around 800 miles), take Route 66 to Santa Monica, then go north along California's coast to San Francisco. It's the longest by far, close to 3,700 miles, and it really needs three weeks. Highway 1 through Big Sur reopened all the way in January 2026 after years of closures, but landslides there are a regular thing, so check Caltrans before you count on it.
For a first crossing I'd do I-80 with detours. It's the version of this trip with a story behind it, and it leaves time for the places that are actually worth stopping for.
How Many Days You Actually Need
The pure driving time from New York to San Francisco on I-80 is roughly 42 to 45 hours. People do it in four days. I wouldn't. Four days means ten or eleven hours a day behind the wheel, and you'll see Nebraska as a blur and Utah in the dark.
Here's a rough guide:
- 6 days - possible, but you're mostly driving. About 500 miles a day.
- 10 days - the sweet spot for most people. Five or six hours of driving a day, a few real stops, one or two rest days.
- 14 days or more - room for detours: Chicago, Rocky Mountain National Park, Salt Lake City, Lake Tahoe.
Whatever you choose, don't plan your longest day for the Sierra Nevada at the end. You'll be tired, and that's the one stretch where weather and mountain driving actually matter.
The Route, Leg by Leg
This is the I-80 version, split the way a 10-day trip naturally falls apart.
New York to Pittsburgh
Leaving Manhattan is the most stressful hour of the whole trip, so do it early on a weekend morning. The good news is that the George Washington Bridge only charges a toll on the way into New York, so heading west it's free. Once you're through New Jersey, Pennsylvania opens up into farmland and ridges. If you have time, follow the old Lincoln Highway (US 30) instead of the interstate: it takes you through Lancaster County, past Gettysburg and over the Allegheny mountains to Pittsburgh. It's slower, but it's the stretch where the old road still feels like a road trip.
Ohio, Indiana and a Detour to Chicago
This is the part people warn you about. It's flat, it's fast, and on I-80 a lot of it is the Ohio Turnpike and the Indiana Toll Road. I-80 passes south of Chicago, and I'd make the detour: one night in the city breaks up the Midwest nicely, and if you want a taste of Route 66, its official start sign is on Adams Street downtown.
Iowa and Nebraska
Cornfields, wind turbines, grain elevators, repeat. It's more pleasant than its reputation, especially in late summer. Two stops that make the miles go faster: Iowa 80 in Walcott, which calls itself the world's largest truck stop and has a trucking museum next door, and the Great Platte River Road Archway in Kearney, Nebraska, a museum built as a bridge right over the interstate. Nebraska follows the Platte River, the same valley the Oregon Trail wagons used, so you're driving one of the oldest routes west.
Wyoming
Somewhere after the Nebraska border the land goes up, the trees disappear and the wind arrives. Between Cheyenne and Laramie, I-80 crosses Sherman Summit at 8,640 feet, its highest point, and the rest area there has a huge bronze head of Abraham Lincoln, first put up in 1959 beside the old Lincoln Highway and moved to the interstate ten years later. After that it's high desert, snow fences and trucks all the way to Utah. Fill up whenever you see a station - the gaps between towns get long here.
Utah
Coming down through Echo Canyon into Salt Lake City is one of the best moments of the trip. Take a night here. West of the city, I-80 runs dead straight across the desert toward Wendover, and for the last stretch before Nevada, a couple of hours out, it's flanked by the Bonneville Salt Flats, a white salt crust so flat that people have set land speed records on it for a hundred years. There's a rest area on I-80 where you can walk out onto the salt (in spring it's often flooded, which makes it a giant mirror instead). Go in the late afternoon, the light is ridiculous.
Nevada: Pick the Loneliest Road
Here you have a real choice. I-80 goes north through Elko, Winnemucca and Reno - easy, reliable, a bit dull. The Lincoln Highway went through the middle of the state on what is now US 50, which Life magazine called "the Loneliest Road in America" in 1986. Nevada turned the insult into a slogan. It goes through Ely, Eureka, Austin and Fallon, with mountain ranges every forty miles and almost nothing in between. If you've come all this way for the feeling of a big empty country, this is where you'll get it. Just leave every town with a full tank.
Over the Sierra to San Francisco
The last mountain range is the Sierra Nevada. I-80 climbs over Donner Summit at 7,240 feet, a couple of miles from Donner Pass, where the Donner Party, a wagon train of pioneers, got trapped by snow in the winter of 1846-47. US 50 takes you past the south shore of Lake Tahoe instead. Either way, you drop down through the foothills to Sacramento, and from there it's about 90 minutes to the Bay Bridge.
If you want to finish the way the Lincoln Highway did, drive across the city to Lincoln Park, next to the Legion of Honor museum. There's a small marker for the western end of the highway, and the view of the Golden Gate from there is the right way to end 3,000 miles.
The Car: Renting One Way
Most people rent. The catch is the one-way fee: picking a car up in New York and leaving it in San Francisco usually costs extra, and it varies a lot between companies and dates. Compare the total price, not the daily rate. A few practical things:
- Pick it up outside Manhattan - rental offices in New Jersey or at Newark airport are usually cheaper, and you skip the worst of the city traffic.
- Unlimited mileage - check that it's included for one-way rentals. On 3,000 miles, a per-mile charge would wreck the budget.
- Tolls - on I-80 you'll pay at the Delaware Water Gap bridge into Pennsylvania, on the Ohio Turnpike and the Indiana Toll Road, on a short stretch near Chicago and on the Bay Bridge into San Francisco, which is electronic only. Rental cars come with a toll pass, which adds a fee of around $5 to $7 for each day you use it (most companies cap it per rental).
- Your license - visitors can drive on their home license, but some states and some rental companies want an International Driving Permit as well. Get one at home before you fly - you can't get it once you're in the US.
When to Go
Late May to June and September to early October are the best windows. The weather is mild across the whole route, the mountain passes are clear and the national parks aren't at their busiest.
Summer works, but the Nevada and Utah desert gets properly hot, and the cities on the east coast are muggy. Winter is the one to avoid unless you know what you're doing. Southern Wyoming is famous for closing I-80 because of blowing snow and wind, sometimes for a day or more, and California regularly requires chains over Donner Summit. If you do go in winter, build in spare days and check the state road reports every morning.
Tolls, Gas and What It All Costs
Gas is the easy part to estimate. A normal rental car will burn something like 100 to 120 gallons on 3,000 miles. In early October 2026 AAA had the national average at $4.37 a gallon and California at $6.38. California is usually the most expensive state in the country, so fill up in Nevada before the last climb.
For a 10-day trip for two people, a realistic budget looks something like this:
- Car - rental plus the one-way fee is the biggest single cost and the hardest to predict. Get quotes early.
- Gas - roughly $450 to $550 at today's prices.
- Motels and hotels - $90 to $150 a night in small towns on the way, much more in New York, Chicago and San Francisco.
- Tolls - well under $100 for the whole crossing, plus the rental company's pass fees.
Book the first and last nights. Everything in between you can mostly figure out on the day, which is half the fun anyway.
Before You Set Off
A coast-to-coast drive goes through eleven or twelve states depending on the route, and honestly, most people would struggle to point to half of them on a blank map. Nebraska and Iowa? Which one is on top? Before you go, try Pinpoint USA - it shows you a state and you drop a pin where you think it is. Ten rounds, from Texas to Rhode Island, and it makes the map in your head a lot sharper. If you'd rather practice on the whole world, Pinpoint does the same with countries, and the United States country page has the basics on the country you're about to cross.
Then fill the tank, put New Jersey in the mirror and keep going until the land runs out.
