Interstate 80 is a trans-continental Interstate Highway in the United States. It starts in the SoMa neighborhood of San Francisco, California and runs 2,901 miles (4,669 km) east to Teaneck, New Jersey. It connects the states of California, Nevada, Utah, Wyoming, Nebraska, Iowa, Illinois, Indiana, Ohio, Pennsylvania, and New Jersey.
Major cities along the route include San Francisco, Oakland, Sacramento, Reno, Salt Lake City, Cheyenne, Lincoln, Omaha, Des Moines, Chicago, Toledo, and the Newark/New York City area.
Understand
[edit]Interstate 80 closely resembles many historically significant routes, including the Lincoln Highway, the Oregon Trail (in Wyoming and Nebraska), the California Trail (in Nevada and California), the first transcontinental airmail route, and the first transcontinental railroad (except in Utah). It also hosts two of the longest straight sections of Interstate in the US, a 75-mile section from Grand Island to Lincoln in Nebraska, and a 44-mile stretch in the Salt Flats of Utah.
I-80 is known as the Dwight D. Eisenhower Highway from San Francisco to Cheyenne.
Prepare
[edit]- See also: Driving in the United States, Winter driving, Hot weather
Be prepared for snow and ice during the winter months, as most of the route gets snowfall. In the snowiest sections, as much as 10-12 feet of snow can drop at a time.
Be weary of road closures along the high and mountainous stretches of Interstate 80. Make sure your vehicle is equipped with tires capable of treading on ice (or studded), equipped with chains, filled with appropriate anti-freeze for a lower freezing point, and equipped with a battery that has no problem starting the car in freezing temperatures.
Western Utah along Interstate 80 can get extreme heat due to it mostly being in a desert. Bring sunscreen and a first-aid kit if you are planning to camp or stay in the area.
Interstate 80 goes through mostly rural land, most prominently from Reno to Salt Lake City, a 518 mile (834 km) stretch of highway with only 9 total cities. Stock up on food and gas before leaving a city or town. Charging stations are few and far between on rural sections.
Get in
[edit]By plane
[edit]The Interstate 80 corridor can be accessed by plane via San Francisco, Reno, Salt Lake City, Lincoln, and Des Moines with airports near or next to the freeway. In other cities, such as Sacramento, Chicago and Cleveland, the airport can be up to 30 miles (48 km) away from the Interstate.
Go
[edit]By train
[edit]The California Zephyr loosely follows I-80 from Emeryville to Chicago.
Drive
[edit]Note: State highways are referenced by their postal abbreviations, e.g., CA-60 means California State Highway 60, MS-15 means Mississippi State Highway 15, etc. Interstate highways are listed with an I- abbreviation, e.g., I-5 means Interstate 5, I-380 means Interstate 380. Attractions and cities are listed in bold are linked to their respective Wikivoyage articles for further reading and discussion. If no such article exists on Wikivoyage it is linked to its Wikipedia article or to it's unmade Wikivoyage page that is empty and can be created. Please feel free to plunge forward to edit this or another article or create a new Wikivoyage article that does not yet exist.
Mile markers are statewide mileposts, starting with "0" at the western border of each state which increases as you go east and then starts over at "0" when crossing the state line into the next state. So going west the numbers on the mileposts will decrease and then start over at the highest number when crossing a state line. The exit numbers correspond with the mileposts so some numbers may be skipped if the exits are further apart from one to the next. Other exits that are one next to the other or "2 in 1" may have the same exit number followed by an "A", "B" or even a "C" such as "Exit #46A" to get on Oak St, "Exit #46B" to get on US 1 and so forth.
All exits are from the eastbound side, unless otherwise stated.
California
[edit]The maximum speed limit is 65 mph (112 km/h) for cars on rural stretches and in urban areas or lower if posted otherwise. Speed limit for large trucks is 55 mph (88 km/h) in both rural and urban areas unless posted otherwise. It is not the usual 70 mph found in every other major highway in California as it goes through either urban or mountainous terrain.

Alternative Routes
[edit]US-50 is the closest alternate route that goes cross-country. It runs from Sacramento to Ocean City, Maryland. However, US-50 is more rural than I-80, and takes a more southern route. It's so rural that the Nevada section of the highway is considered the "Loneliest Road in America".
Stay safe
[edit]As noted before, parts of I-80 get some of the most severe and coldest weather in the US. Always bring chains and antifreeze on you if you are going through steep and snowy terrain and make sure your battery can start up in freezing weather.

Snakes and scorpions are common in rural Utah. Be aware of your surroundings when driving, walking, camping, or even using the bathroom.
Also in rural Utah and other rural areas, cell phone service is spotty at best, but most likely non-existent. If you plan to travel in these areas, be sure to have alternate communication methods available (satellite phone, CB radio, amateur radio, signaling mirrors or lighting, etc.).
Never head far out into the desert without reserve water and gasoline. Expect to need a gallon of water per day per person in the event that an emergency situation develops. You should also carry sunscreen and a first aid kit in case you are unable to return immediately.
Go next
[edit]
Interstate 5 connects the West Coast together. It has some of the most scenic views you will ever see, like Mount Shasta and the western Cascade Mountains.
Interstate 10 is the southern version of Interstate 80.
