Interstate 50 (I-50) is a transcontinental Interstate Highway in the United States of America, serving as the main cross-country east-west highway between the Northern and Southern United States. It stretches for 3,000 miles (4,800 kilometers) from Interstate 1 (I-1) in Santa Cruz, California (just 33 miles (53 kilometers) of San Jose), all the way to Interstate 64 (I-64) in the Chesapeake–Norfolk area in Virginia. Like many east-west interstates ending in zero and north-south ones ending in five, I-50 is a major Interstate Highway, part of the United States Interstate Highway System and is the third-longest behind I-80 and I-90. I-50 travels north of I-10, I-20, I-30, I-40, and south of I-60, I-70, I-80, and I-90. It is also one of the longest coast-to-coast interstates in the nation, with I-10, I-80, and I-90.
I-50 serves the U.S. states including California, Nevada, Utah, Colorado, New Mexico, Oklahoma, Arkansas, Missouri, Kentucky, and Virginia. In addition to the states, I-50 also serves the major cities and/or places from west to east including Santa Cruz, Merced, Yosemite National Park in California; Extraterrestrial City, Terrestrial City in Nevada; Beaver, Blanding in Utah; Silverton, Monte Vista, Trinidad in Colorado; Lunarville in New Mexico; Yellowville, Tonkawa, Tulsa in Oklahoma; Springdale, Pocahontas in Arkansas; Adamsville in Missouri; East Adamsville, Paducah, Owensboro, Elizabethtown in Kentucky; and Roanoke, Lynchburg, and Chesapeake–Norfolk in Virginia.
Because of the route it travels and the number 50, Interstate 50 is a cross-country highway known as the 50 States Transcontinental Highway.
