U.S. Route 20 or U.S. Highway 20 (US 20) is an east–west United States Highway, United States Numbered Highway that stretches from the Pacific Northwest east to New England. The "0" in its route number indicates that US 20 is a major coast-to-coast route. Spanning , it is the longest road in the United States, and, in the east, the route is roughly parallel to that of the newer Interstate 90 (I-90), which is the longest Interstate Highway System, Interstate Highway in the U.S. There is a discontinuity in the official designation of US 20 through Yellowstone National Park, with unnumbered roads used to traverse the park.
US 20 and U.S. Route 30, US 30 break the general U.S. Route numbering rules in Oregon, since US 30 actually starts north of US 20 in Astoria, Oregon, Astoria, and runs parallel to the north throughout the state (the Columbia River and Interstate 84 (Oregon–Utah), Interstate 84). The two concurrency (road), run concurrently and continue in the correct positioning near Caldwell, Idaho. This is because US 20 was not a planned coast-to-coast route while US 30 was. US 20 originally ended at the eastern entrance of Yellowstone Park; it was extended in 1940.
The highway's eastern terminus is in Boston, Boston, Massachusetts, at Kenmore Square, where it meets Massachusetts Route 2. Its western terminus is in Newport, Oregon, at an intersection with U.S. Route 101, US 101, within a mile of the Pacific Ocean.
US 20 begins at an intersection with U.S. Route 101 (Oregon), US 101 in Newport, Oregon, and runs generally eastward towards Idaho. On the way it goes over the Central Oregon Coast Range, through several Willamette Valley cities including Corvallis, Oregon, Corvallis and Albany, Oregon, Albany, climbs the Cascade Range, Cascade Mountains over Santiam Pass, goes through Bend, Oregon, Bend, and traverses the High Desert (Oregon), Oregon High Desert after passing through Burns, Oregon, Burns. It eventually overlaps U.S. Route 26 in Oregon, US 26 in Vale, Oregon, Vale, and the two highways continue concurrently to the Idaho border.
Within Nebraska, US 20 is a Nebraska State Highway System, state highway that begins on the Wyoming–Nebraska state line west of Harrison, Nebraska, Harrison near the Niobrara River and runs to the Nebraska–Iowa state line in South Sioux City, Nebraska, South Sioux City. Throughout its length the route passes through a diverse range of landscapes including Beach ridge, bluffs and escarpments in the Northwest Nebraska Panhandle, Panhandle, the Nebraska Sandhills in the northern part of the state, and rolling hills and plains as the highway approaches the Missouri River valley south of Sioux City, Iowa. Throughout its length, US 20 is a two-lane highway with the exception of the easternmost which is four-lane divided highway, the last of which is concurrent with Interstate 129.

After skirting the southeast side of Sioux City as a freeway with US 75, US 20 continues east as an Limited-access road, expressway to Moville, Iowa, Moville. From Moville through north of Early at the junction with U.S. Route 71 and Iowa Highway 471, US 20 was reconstructed from a rural two-lane highway to a four-lane road. This segment re-opened October 19, 2018 and made it so that US 20 is a continuous four-lane highway for its entire length in Iowa. It passes to the north of Sac City, Iowa, Sac City, where it has another interchange with the realigned U.S. Route 71, then passes to the south of Fort Dodge, Iowa, Fort Dodge and Webster City, Iowa, Webster City before intersecting Interstate 35, I-35 near Williams, Iowa, Williams.
A new segment of freeway between U.S. Route 65, US 65 south of Iowa Falls, Iowa, Iowa Falls and Iowa Highway 14 opened in 2003 creating a continuous four-lane route from Moorland to Dubuque. The new segment shaved off US 20's length in Iowa. In the Waterloo, Iowa, Waterloo/Cedar Falls, Iowa, Cedar Falls area, the segment of US 20 overlapped by the Avenue of the Saints, which is also designated as Iowa Highway 27. US 20 passes Independence, Iowa, Independence, Manchester, Iowa, Manchester, and Dyersville, Iowa, Dyersville before reaching Dubuque, Iowa, Dubuque. At Dubuque, US 20 crosses into Illinois over the Julien Dubuque Bridge.
In the state of Indiana, US 20 enters from the west beneath the Chicago Skyway with US 12 and US 41.

East of Cleveland US 20 follows the southern shore of Lake Erie, following Euclid Avenue (Cleveland, Ohio), Euclid Avenue from Public Square, and traverses Euclid, Ohio, Euclid, Wickliffe, Ohio, Wickliffe, where it intersects with I-90, Mentor, Ohio, Mentor, Painesville, Ohio, Painesville, Madison, Ohio, Madison, Geneva, Ohio, Geneva, Ashtabula, Ohio, Ashtabula and crosses into Pennsylvania at Conneaut, Ohio, Conneaut.
US 20 runs for nearly across Erie County, Pennsylvania, most of that time just south of the CSX Transportation, CSX/Amtrak railroad tracks. US 20 appears as West Ridge Road eastward from the Ohio border through Springfield Township, Erie County, Pennsylvania, Springfield, Girard Township, Erie County, Pennsylvania, Girard, Fairview Township, Erie County, Pennsylvania, Fairview and Millcreek Township, Erie County, Pennsylvania, Millcreek townships. At the intersection with Pennsylvania Route 832, just outside the Erie, Pennsylvania, Erie city limits, it becomes West 26th Street.

It turns sharply northward as Broad Street at the Bayfront Connector, then turns east again as Buffalo Road through Wesleyville, Pennsylvania, Wesleyville and Harborcreek Township, Erie County, Pennsylvania, Harborcreek Township. Buffalo Road turns sharply northward at the town of Harborcreek. US 20 intersects with Pennsylvania Route 955 and resumes its eastward journey. At North East Township, Erie County, Pennsylvania, North East Township, US 20 becomes West Main Road. Within the town limits, it becomes West Main Street until it reaches the town center at its intersection with Pennsylvania Route 89, where it becomes East Main Street. Outside the town limits it becomes East Main Road until it reaches Pennsylvania's border with New York (state), New York.
In New York (state), New York, US 20 runs roughly parallel to the New York State Thruway (I-90) throughout the state.

US 20 runs across the rural Cherry Valley Turnpike between Skaneateles (town), New York, Skaneateles and Albany, New York, Albany. US 20 was also known as the Boston-Buffalo highway prior to the construction of the New York Thruway and Massachusetts Turnpike.
In Massachusetts, US 20 runs near I-90 Mass Pike, intersecting it directly at exit 10 and indirectly at exit 94.
In part of Berkshire County, Massachusetts, Berkshire County, US 20 runs north–south as it runs concurrently with U.S. Route 7, US 7. It is known as the "Jacob's Ladder Trail" as it crosses the The Berkshires, Berkshire Hills between Lee, Massachusetts, Lee in Berkshire County and Chester, Massachusetts, Chester in Hampden County, Massachusetts, Hampden County. From Chester to Westfield, Massachusetts, Westfield, US 20 and the Boston and Albany Railroad follow the Westfield River down to the broad valley of the Connecticut River.
In Springfield, Massachusetts, Springfield, US 20 runs concurrently with Interstate 291 (Massachusetts), I-291 between Plainfield Street and Page Boulevard; it follows Boston Road as it leaves Springfield and travels through the town of Wilbraham, Massachusetts, Wilbraham, eventually becoming Main Street in Palmer, Massachusetts, Palmer.
In Shrewsbury, Massachusetts, Shrewsbury, US 20 is called "Hartford Turnpike". In Northborough, Massachusetts, Northborough, and Worcester, Massachusetts, Worcester it is called "Southwest Cutoff", until it merges with the original Boston Post Road in Northborough (Southwest Cutoff and West Main Street). Southwest Cutoff was created at the turn of the century to bypass truck traffic around Shrewsbury center as well as connecting to the Massachusetts Route 9, Boston and Worcester Turnpike.
In parts of eastern Massachusetts, US 20 follows the route of the old Boston Post Road and passes by Henry Wadsworth Longfellow, Longfellow's Wayside Inn, in Sudbury, Massachusetts, Sudbury, the oldest continually operated Inn in America. In 1926, after engineers determined that heavy truck traffic on the Boston Post Road was damaging the foundations of the Inn, Henry Ford, then owner and proprietor, ordered the construction of the mile-and-a-half-long Route 20 bypass. Upon its completion on December 11, 1928, he sold it to the Commonwealth of Massachusetts for $1 and never cashed the check. According to the Boston Herald the by-pass cost Ford $288,000, equivalent to roughly $4.7 million in 2021. The original route of US 20 is now called Wayside Inn Road.
US 20 continues from Sudbury through Wayland, Massachusetts, Wayland, Weston, Massachusetts, Weston, Waltham, Massachusetts, Waltham, Watertown, Massachusetts, Watertown and then into Boston, Massachusetts, Boston through Allston and Fenway–Kenmore. U.S. Route 20's official eastern terminus is in Kenmore Square at the intersection of Commonwealth Avenue (Boston), Commonwealth Avenue, Beacon Street, and Brookline Avenue, where the alignment becomes Massachusetts Route 2. Route 2 continues for a short distance where it terminates at Massachusetts Route 28.
Before the U.S. Highway System, the route in New England and New York was designated as New England Interstate Route 5 (NE-5), part of the New England Interstate Route system that existed between 1922 and 1927. Around 1923, from Springfield to Pittsfield, NE-5 was known as "Jacob's Ladder", and from Boston to Albany, the "Hubway". When US 20 was first commissioned, it took over the entirety of NE-5.
The 1953 Massachusetts Department of Public Works Master Plan would have relocated US 20 between Palmer, Massachusetts and either West Springfield, Massachusetts or Westfield, Massachusetts along the right-of-way now used by the Massachusetts Turnpike, but this was never implemented. Until 1970–72, US 20 followed an old route through downtown Springfield—Boston Road and State Street—crossing the Connecticut River via the older Memorial Bridge (Massachusetts), Memorial Bridge (now Massachusetts Route 147). The construction of Interstate 291 (Massachusetts), I-291 prompted a change. US 20 now crosses from West Springfield at the North End Bridge, and is co-signed with I-291 until Page Boulevard, where it heads back to Boston Road via the former route of 20A. In 2012, the Historic US Route 20 Association was formed to identify, promote and preserve the history of the route and original alignments that were once signed "Route 20" from Boston to Newport, Oregon, Newport.
*Between Fremont, Ohio, Fremont, Ohio and Perrysburg, Ohio, Perrysburg, Ohio, the road dates back to the late 1830s. It was known then as the Maumee and Connecticut Western Reserve, Western Reserve Road. Nicknamed "Mud Pike" and earned a reputation as "The worst road on the continent" for the mudholes that would trap wagon wheels and slow draft animals. Travelers sometimes would take three days to travel . It is still signed as Maumee St. in and near Angola, IN.
*Through western Indiana, US 20 was built as the Dunes Relief Road, as it bypassed the heavily traveled Dunes Highway.
*Northwest of Chicago it is called Ulysses S. Grant Highway.
*On March 25, 2019, Idaho officially labeled their section of US 20 as the Idaho Medal of Honor Highway in honor of 48 Medal of Honor Recipients with strong Idaho attachments.

History
Before the U.S. Highway System, the route in New England and New York was designated as New England Interstate Route 5 (NE-5), part of the New England Interstate Route system that existed between 1922 and 1927. Around 1923, from Springfield to Pittsfield, NE-5 was known as "Jacob's Ladder", and from Boston to Albany, the "Hubway". When US 20 was first commissioned, it took over the entirety of NE-5.
