Interstate 80 (abbreviated I-80) is the second-longest Interstate Highway in the United States. It connects downtown San Francisco, California to the suburbs of New York, just as the Lincoln Highway did in the years before the Interstate Highway System. The highway roughly traces some historically significant travel corridors, particularly in the Western U.S. These include the Oregon Trail in Nebraska and westward and the California Trail in Nevada and California.

The highway from near Chicago, Illinois east to near Youngstown, Ohio is a toll road - the end-to-end Indiana Toll Road and Ohio Turnpike. At Youngstown I-80 leaves the tolled alignment, which continues towards New York as the Pennsylvania Turnpike and New Jersey Turnpike, in favor of the Keystone Shortway, a shortcut across northern Pennsylvania built as part of a new corridor for I-80. The tolled route to Philadelphia, Pennsylvania was originally designated Interstate 80S, and is now Interstate 76.

Notes

  • Among many picturesque sections of I-80 are the crossing of San Francisco Bay over the San Francisco-Oakland Bay Bridge (toll paid westbound only), the traverse above Donner Pass and Donner Lake (near Lake Tahoe) in California, and its run along the Truckee River both west and east of Reno, Nevada. Interstate 80 crosses the southern end of Great Salt Lake west of Salt Lake City, Utah, providing views of various mountains, although it incorporates a very long stretch of straight roadway that can induce some drivers to fall asleep. Also in that category, is the stretch of I-80 from east of Rock Springs, WY to Laramie, WY (around 200 miles). It passes through the Red Desert just prior to Rawlins and is always very windy.

  • The longest stretch in between exits on an Interstate Highway is between Wendover and Knolls in Utah, with 37 miles between those exits.

  • All of I-80 in Indiana is duplexed with another interstate, such as I-90 or I-94.

  • Contrary to the opinions of some interstate enthusiasts, the longest straight (by any reasonable definition of "straight") stretch of interstate anywhere in the system is the approximately 72 miles of I-80 occurring between Exit 318 and milemarker 390 in Nebraska. Along this length the road does not vary from an ideally straight line by more than a few yards.

  • Although Interstate 80 does not enter Colorado, it does manage to come within a mile of the border between Nebraska and Colorado at the junction of Interstates 80 and 76. This intersection is visible from Colorado as one approaches it from the west on I-76.

  • Although it never enters Michigan, Interstate 80 (with Interstate 90) lies within ten miles (16.1 km) of the Michigan state line between La Porte, Indiana and Toledo, Ohio. Looking north at the intersection of Indiana State Highway 9 and I-80, the "Welcome to Michigan" sign is visible in the distance.

  • I-80 does not go all the way to New York City via the George Washington Bridge. Its designated end is about four miles (6.4 km) short of New York City in Teaneck, New Jersey. There, it joins and becomes designated as I-95, which does cross the bridge. The tolled section of the New Jersey Turnpike ends at exit 18, which is actually just the toll plaza at the northern terminus. The next exit on I-95 is exit 68, which is consistent with the exit structure on I-80. (The truth is that the exit numbers on this section of I-95 match the mile markers on I-95 had the Somerset Freeway been built. The fact that they are similar to what the exit numbers are on I-80 is just a coincidence.)

  • The portion of 80 that goes through New Jersey is sometimes called the Bergen-Passaic Expressway.
