Interstate 80
Encyclopedia : I : IN : INT : Interstate 80
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.

Auxiliary routes
- Interstate 280 runs from downtown San Francisco south to San Jose, where it becomes I-680 at U.S. Route 101. There is no freeway-to-freeway connection between I-280 and I-80 in San Francisco.
- Interstate 380 runs east from I-280 to San Francisco International Airport.
- Interstate 480 was the Embarcadero Freeway in downtown San Francisco, now demolished. Oddly, this freeway was signed as State Route 480.
- Interstate 580 runs from I-80 in Oakland southeast and east to I-5 south of Tracy, forming part of the route between the Bay Area and Los Angeles. From Oakland it continues north with I-80 to Richmond, where it splits northwest to San Rafael.
- Interstate 680 runs from I-80 near Fairfield south across I-580 to the south end of I-280 at US 101 in San Jose.
- Interstate 780 connects I-80 in Vallejo to I-680 at Benicia.
- Interstate 880 runs from I-80 in Oakland south to I-280 in San Jose. The number was originally used for the Sacramento bypass, now part of I-80.
- Interstate 980 is a short connection between I-580 and I-880 in Oakland.
- Interstate 180 was a temporary designation for the Richmond-San Rafael section of I-580. It was renumbered because California already had a State Route 180.
- Interstate 238 is a short connection between I-580 and I-880 near Hayward. Formerly part of State Route 238, it was assigned a nonstandard number because all possible auxiliary numbers of I-80 were in use. It is thus not an auxiliary route of I-80, but it would have been if the situation was different at the time.
- Interstate 580 is a partially-completed unsigned spur from I-80 in Reno, Nevada south to Carson City.
- Interstate 180 is a spur into downtown Cheyenne, Wyoming. It falls far short of meeting Interstate standards, as no part of it is a freeway.
- Interstate 180 is a spur into downtown Lincoln, Nebraska.
- Interstate 480 is a short half-loop through downtown Omaha, Nebraska, from I-80 north and east to I-29 in Council Bluffs, Iowa.
- Interstate 580 was a spur from I-480 north along U.S. Route 75.
- Interstate 680 is a bypass around the north side of Omaha, Nebraska and Council Bluffs, Iowa.
- Interstate 380 is a spur from near Iowa City, Iowa north past Cedar Rapids into Waterloo.
- Interstate 280 is a half-loop around the south side of the Quad Cities, from I-80 west of Davenport, Iowa to I-80 and I-74 east of Moline, Illinois.
- Interstate 180 is a spur to Hennepin, Illinois.
- Interstate 280 is a spur from I-80 (and I-90) southeast of Toledo, Ohio northwest to I-75 in Toledo.
- Interstate 480 is a loop through the south side of Cleveland, Ohio.
- Interstate 680 is a connection through downtown Youngstown, Ohio, from I-80 northwest of downtown to I-76 south of downtown.
- Interstate 180 is a spur to Williamsport, Pennsylvania.
- Interstate 380 is a spur from near Stroudsburg, Pennsylvania northwest to I-81 and I-84 near Scranton.
- Interstate 280 runs from I-80 in Parsippany-Troy Hills, New Jersey southeast through downtown Newark to I-95 near Jersey City.
- Interstate 80N is now Interstate 84 from I-80 at Echo, Utah northwest to Portland, Oregon.
- *Interstate 180N is now Interstate 184, a spur into Boise, Idaho.
- Interstate 80S is now Interstate 76 from I-80 at Big Springs, Nebraska southwest to Denver, Colorado.
- Interstate 80N is now part of Interstate 680, connecting I-80 to I-29 north of Council Bluffs, Iowa.
- Interstate 80N was roughly replaced with Interstate 480 through Cleveland, Ohio, though its original route continued in both directions.
- Interstate 80S is now Interstate 76 from I-71 near Lodi, Ohio to I-80 near Youngstown, Ohio and beyond to near Camden, New Jersey.
- *Interstate 176, Interstate 276, Interstate 476 and Interstate 676 in Pennsylvania and New Jersey were once I-180, I-280, I-480 and I-680.
Notes
- The highway reaches a maximum elevation of 8,640 feet (2,633 m) above sea level between Cheyenne and Laramie, Wyoming. Farther west in Wyoming, the interstate passes the Continental Divide twice because two lines of mountains form a closed-off basin.
- 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.
- I-80 intersects I-90 near Elyria, Ohio and they share a route all the way to Portage, Indiana, where I-90 splits off but I-80 then runs concurrently with I-94 until the Chicago suburb of South Holland, Illinois. I-80 then runs concurrently with I-294 until Markham, Illinois.
- 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.)
- Part of Interstate 80 in Nebraska is known as the Blue Star Memorial Highway.
- The portion of 80 that goes through New Jersey is sometimes called the Bergen-Passaic Expressway.
Major bridges on I-80
- San Francisco-Oakland Bay Bridge
- Fred Schwengel Memorial Bridge
- Al Zampa Bridge; the newest suspension bridge in the United States. It is one of the spans of the Carquinez Bridge.
- Des Plaines River Bridge
