# Interstate 90

Interstate 90 (I-90) is a United States interstate highway that starts in Seattle, Washington and runs 3,021 mi (4,862 km) east through the states of Washington, Idaho, Montana, Wyoming, South Dakota, Minnesota, Wisconsin, Illinois, Indiana, Ohio, Pennsylvania, New York and Massachusetts in the East Coast in Boston. It serves as an important northern tier transcontinental highway across the Pacific Northwest, Rocky Mountains, Great Plains, the Midwest and the northeastern U.S. connecting the major cities of Seattle, Spokane, Washington; Billings, Montana; Sioux Falls, South Dakota; Rochester (Minnesota); Madison, Wisconsin; Rockford, Illinois; Chicago, South Bend, Indiana; Toledo, Ohio; Cleveland, Erie; Buffalo, Rochester_(New York), Syracuse_(New York), Albany, Springfield_(Massachusetts) and Boston; and the four state capitals of South Dakota (Pierre); Wisconsin (Madison), New York (Albany), and Massachusetts (Boston). It is the longest transcontinental interstate highway across the United States.

## Understand

Intestate 90 replaces US Hwy 10 from Seattle to Billings; follows US 87 between Billings and Buffalo, Wyoming; replaces US 14 & 16 between Buffalo and Tomah, Wisconsin; bypasses US 12 between Tomah and Portage; parallels US 51 from Portage to Rockford, Illinois. From South Beloit, Illinois to Boston, I-90 follows a series of toll highways (turnpikes) across the eastern half of the route. Namely along The Jane Addams Memorial Tollway (formerly Northwest Tollway), Chicago Skyway, Indiana Toll Road, Ohio Turnpike, New York State Thruway, and Massachusetts Turnpike which all predate the interstate highway system except in Pennsylvania where I-90 remains toll-free. I-90 is paired with I-80 on the Indiana Toll Road and the Ohio Turnpike between Chicago and Cleveland. US Hwy 20 (which still exists) predates and parallels the toll highways between Rockford, Illinois and Boston, Massachusetts through the same cities and towns as I-90. I-90 and 94 in Wisconsin and west of Wisconsin remain toll-free.
Interstate 94 (I-94) branches from I-90 (exit 494) in Billings, Montana as a northern branch of I-90. It continues east, 1,555 mi (2,503 km), across Montana, North Dakota, Minnesota, Wisconsin, Illinois, Indiana and Michigan to its eastern terminus at the Canadian border in Port Huron, Michigan. It intersects I-90 in Billings, Montana; Tomah, Wisconsin; Madison, Wisconsin; Chicago, Illinois; and Lake Station, Indiana. I-94 runs concurrent with I-90 between Tomah and Madison, Wisconsin and in Chicago. It connects Billings, Bismarck, Fargo, Minneapolis–Saint Paul, Madison, Milwaukee, Chicago, Lake Station, and Detroit.

## Prepare

    See also: Winter driving
When on the road, most of the journey is straightforward freeway driving. If it is winter, it is wise to check the weather and traffic conditions east of the Cascades (in Washington), through the Rocky Mountains and across the Great Plains and the Midwest. Between the Cascades and New York State. Snowy conditions are not uncommon, and officials usually close the road if things become too dangerous at any point along the highway, at varying distances. In some areas the road may be dry and passable while in other areas the road may be closed due to blizzard like weather. Parallel US, state or local highways may or may not be passable during the winters as not all are plowed and maintained during the winter.
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 will have no problems starting the car in freezing temperatures. Also make sure the vehicle has a full tank of gas before leaving a city, town or from last night's accommodations as services may be further apart. Charging stations for electric vehicles are fewer and far in between in remote rural areas.

## Get in

Interstate 90 begins/ends at its junction with 4th Ave S, South of Downtown Seattle (SODO) at T-Mobile Park (stadium for the Seattle Mariners) & Lumen Field (home of the Seattle Seahawks) in its western terminus. In the eastern terminus it begins/ends at its intersection with MA-1A at Boston Logan International Airport. The road then continues north of Logan Airport, the next 5 mi (8.0 km), as MA-A1 which curves west as MA-60 and ends at its intersection with US-1 in Revere. I-90 intersects other major US interstate highways (Interstates 5, 82, 15, 94, 25, 29, 35, 39, 41, 55, 57, 69, 75, 80, 86, 87, 84, 95, and 93); various three digit interstates (serving as local auxiliary highways); state highways, U.S highways and local roads in the 13 states where travelers can enter and leave I-90.

* Greyhound Lines/Flixbus, toll-free: +1-800-231-2222. Greyhound does not travel the entire length of I-90. Their routes are segmented between Seattle-SpokaneMinneapolis-St Paul-Wisonsin Dells-Milwaukee-Chicago. They only travel I-90 between Minneapolis and Wisconsin Dells aen then on I-94 into Chicago via Milwaukee. Some of the schedules between Minneapolis to Chicago are served by Jefferson Lines.Chicago-ClevelandCleveland-Buffalo-Syracuse-AlbanyAlbany-Springfield, MA -Boston South station Travelers booking tickets between Boston and Chicago are typically routed through New York via Pittsburg or via Baltimore to get towards Chicago as services between Albany and Buffalo are limited. Greyhound does not travel the sections of I-90 between Spokane and Minneapolis but rather sell tickets on Jefferson Lines (see below). See their schedules/websites for a list of additional stops between the listed cities. (updated Jun 2023)

## Drive

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.

### Washington

In Washington, I-90 was built over much of US 10 through a series of upgrades to the road. New sections of I-90 were built to bypass Cle Elum, Ellensburg, Moses Lake, Ritzville, Spokane and Spokane Valley with the old US 10 going in through town as Business Loop 90, as a local surface street. The stretch of the old US 10 between Cle Elum (exit 85) and its intersection with US 97 west of Ellensuburg (exit 106) have been renumbered to WA-10 which runs alongside I-90 as a separate road.

### Indiana

The Indiana Toll Road is part of the Interstate Highway System which runs 156.28 mi (251.51 km) through Indiana connecting the Chicago Skyway to the Ohio Turnpike. The toll road is signed with I-90 for its entire length, as well as I-80 east of Lake Station, after having run concurrently with I-94.
I-94 enters Indiana from Illinois running concurrently with I-80 and US Highway 6 (US 6) on the separate Frank Borman Expressway, in Munster. It goes across to Lake Station where it intersects I-90. From Lake Station, I-94 continues northeast towards Michigan while I-80 goes concurrent on I-90 on the Indiana Toll Road into Ohio. US 6 leaves the Frank Borman Expressway at Exit 15/15A in Lake Station and continues east towards Sandusky, Ohio as a separate road south of the Indiana Toll Road.
US 20 in Indiana is a main east–west highway that is parallel to the Indiana Toll Road. The western terminus of US 20 is at the Illinois state line and the eastern terminus is at the Ohio state line.

The Massachusetts Turnpike (I-90 in MA)] spans 138 mi (222 km) as the longest east-higway across Massachusetts. The turnpike enters via West Stockbridge from New York state, linking with the Berkshire Connector portion of the New York State Thruway and ends at the Boston Logan Airport east of Boston. US 20 runs its easternmost 153 miles (246 km) through Massachusetts. The highway crosses the state border from New Lebanon, New York, into Hancock and runs eastward to Boston, where it ends at MA-2 in Kenmore Square. It spends the vast majority of its journey paralleling I-90 (Massachusetts Turnpike), which has largely superseded US 20 for through Massachusetts since 1957 when the turnpike opened.

## Alternative routes

    Interstate 94 (I-94) is the northernmost highway that starts at its junction with I-90 (exit 494) in Billings, Montana. It continues east, 1,555 mi (2,503 km), across Montana, North Dakota, Minnesota, Wisconsin, Illinois, Indiana and Michigan to its eastern terminus at the Canadian border in Port Huron, Michigan, where it crosses into Point Edward, Ontario on the Blue Water Bridge. The same road continues another 293 km east to Toronto (via London) as ON-402 & 401. From Point Edward to London as ON-402, and as ON-401 from London to Toronto. I-94 intersects I-90 in Billings, Montana; Tomah, Wisconsin; Madison, Wisconsin; Chicago, Illinois; and Lake Station, Indiana. I-94 is concurrent with I-90 between Tomah and Madison, Wisconsin and again through downtown Chicago to the South side of Chicago on the I-94 Express. I-90 & 94 are most direct east-west highways between Seattle and Toronto via Billings (Jct I-90/94) and Port Huron. It is the only east-west highway to cross the US/Canadian border. It connects Billings, Bismarck, Fargo, Minneapolis–Saint Paul, Madison, Milwaukee, Chicago, and Detroit.
    US 10 goes from its junction with I-94 & US 52 in West Fargo to Manitowoc, Wisconsin through Minnesota and Wisconsin. It goes across Lake Michigan on the USS Badger ferry from Manitowoc to Ludington, Michigan where it continues across West and Central Michigan to its eastern terminus at I-75 in Bay City. Historically US 10 was a continuous highway between Seattle and Bay City via Lake Michigan but has since been decommissioned and replaced by Interstates 90 and 94 to go across North Dakota, Montana, Idaho and Washington into Seattle. Remnants of the old US 10 alongside I-90 and 94 have been re-numbered as Business Loop or Spur 90 or 94 (green shields) to access the cities and towns from the interstate highway. Other remaining sections of the old US 10 have been renumbered as a state highway in Montana, North Dakota and Washington or as a locally named or numbered road without a state or US highway designation in various places.
    US 12 is a 2,500 mi (4,000 km) long highway between Aberdeen, Washington and Detroit, Michigan. It is mostly superseded by Interstate 90 (I-90) and I-94, but, unlike most U.S. Highways that have been superseded by an Interstate, US 12 remains intact as an important link for local and regional destinations alongside I-90 and 94.
    US 16 goes from the eastern gate of Yellowstone National Park to it junction with I-190 in Rapid Falls, through Mount Rushmore National Park in the Black Hills National Forest. Historically US 16 was a continuous highway between Detroit and Yellowstone National Park via Lake Michigan but has since been decommissioned and replaced by Interstate 90 (I-90) between Rapid Falls, South Dakota and Dexter, Minnesota; and by I-96 between Muskegon and Detroit, Michigan. From Rapid Falls to Dexter the old US 16 still remain alongside I-90 as a two lane road with different state highway and county road designations. Between Dexter and Milwaukee the old US 16 has been renumbered as State Route (SR) 16 in both Minnesota and Wisconsin. WIS-16 parallels I-90 or 94 across Wisconsin.
    US 20 is the longest east-west across the United States spanning 3,365 mi (5,415 km) between Florence, Oregon and Boston, Massachusetts. It is superseded by the toll highways (I-90) between Rockford, Illinois and Boston, Massachusetts but remains intact. It closely parallels I-90 through Chicagoland (in Illinois); Indiana, Ohio, Pennsylvania, New York and Massachusetts with some sections of US 20 intersecting I-90 in some places.
    The Lincoln Highway is a historic trans-continental highway that starts in Times Square in New York City and runs approximately 3,142 mi (5,057 km) west through the states of New Jersey, Pennsylvania, West Virginia, Ohio, Indiana, Illinois, Iowa, Nebraska, Colorado, Wyoming, Utah, Nevada and California; to Lincoln Park in San Francisco, California. US 30 carries much of the Lincoln Highway from Philadelphia to Granger, Wyoming. Interstates 76 and 80, in turn, supersedes US 30 between Philadelphia, Pennsylvania and Granger, Wyoming with a section of I-80 concurrent with I-90 on the Ohio Turnpike, Indiana Toll Road and the Chicago Skyway.

* The American Industry Tour showcases the industrial heritage of the Northeastern United States. As many other historical trails in North America, the tour follows migration routes from east to west, with a chronology from colonial times to the present day. Starting in Boston in the 17th and 18th centuries, we visit the 19th century factory clusters around Albany and New York City, and carry on through industrial regions of Pennsylvania, Ohio and Michigan, which had their heyday during the 20th century, ending in Chicago. Many of the places named in the article are accessible from I-90.
* Interstate 5 (I-5) (Old U.S. Hwy 99) Interstate 5 serves as the main north-south interstate along the west coast, between Blaine, Washington at the Canadian border to San Ysidro at the Mexican border, south of San Diego. It replaces much of US 99 from Blaine, Washington to Los Angeles, California and US 101 from Los Angeles (where US 101 presently truncates at) to San Diego California. I-90 intersects I-5 in Seattle.
* The Jazz Track is an itinerary for visiting jazz-related places (particularly big band and traditional jazz) in the United States. Along I-90 Chicago is one of several jazz related places mentioned in the article.
* Mississippi River
* The Mohawk Trail was a historical Native American migratory game path. Today it is Massachusetts Route 2, a 63-mile east-west highway that extends from the Massachusetts-New York line to Millers Falls on the Connecticut River. The Mohawk Trail features over 100 attractions and has been recognized as one of the best scenic routes in the United States
* The Mountains to Sound Greenway is the stretch of I-90 from Seattle through the Cascade Mountains to Ellensburg. It was the first interstate designated as a National Scenic Byway.
* Pan American (PanAm) Highway In the U.S. all interstate highways make up the 'Pan-American' highway which spans from the northern coast of Alaska to the Darien Gap in Panama. Interstate 90 intersects a the CANAMEX_Corridor, a variation of the Pan-Am Highway from the southern end of the Alaska Highway in Dawson Creek, BC; through Alberta, the United States and eventually into Mexico City at Interstate 15 in Butte, Montana. Another variation of the Pan American Highway connects El Paso at the Mexican border to northern Saskatchewan in Canada by way of I-25/US Hwy 85 in the U.S., and a variety of provincial highways through Saskatchewan which would intersect I-90 at its intersection with I-25 in Wyoming.
* From Plymouth to Hampton Roads is an itinerary along the Atlantic coast of the United States, showcasing the nation's early history, from the first Anglo-American settlements in the 17th century to the American Civil War, which ended in 1865.
* Route 66 (aka Old US 66) was a highway that extended from Chicago to Los Angeles. It crossed much of the American Midwest, Great Plains, and Southwest. Although Highway 66 is no longer commissioned as a US Highway, it represents a multitude of ideas: freedom, migration West, and the loneliness of the American heartland. More than four-fifths of it remain drivable (though not always well-marked) as a collection of state highways and local roads. Radiator Springs is a fictional village on Route 66, depicted in the 2006 Pixar animated film, Cars with real places along the US Route 66 as the backdrop. The eastern terminus of Route 66 is at E Jackson Blvd & Lakeshore Dr (US 41) in downtown Chicago nearest the junction of I-90/94 and I-290/IL-110. From the EB lane of I-90/94 exit at 51E and go east on W Monroe towards Lake Shore Dr (US 41). From the WB lanes of I-90/94 go east on IL-110 towards Lake Shore Dr. One can also travel along I-55 from south of downtown Chicago towards St Louis, as I-55 follows alongside the Route 66 between Chicago and St Louis.
* US Highway 1 predates the interstate highway system (Interstate 95) still in existence along the eastern seaboard. It connects Fort Kent, Maine in the north to Key West, Florida in the south. I-90 terminates at US 1 as MA-60 in Boston.
* The "Underground Railroad" is a network of disparate historical routes used by African-American slaves to escape the United States and slavery by reaching freedom in Canada and the northern free states. Today many of the stations along the "railroads" serve as museums and memorials to the former slaves' journey north. Many of which are located in the northern states served by Interstate 90.
