U.S. Route 50 (US 50) is a major east–west route in the state of Missouri.

Route description

US 50 enters Missouri from Kansas along Interstate 435 around Kansas City and then it runs concurrently with Interstate 470 to Lee's Summit. It then runs as an expressway to Sedalia before becoming Broadway Boulevard and intersecting with U.S. Route 65 (Limit Avenue). From Sedalia to California, US 50 becomes a 2-lane undivided road, where it has a concurrency with Highway 5 from Syracuse to Tipton between Morgan and Moniteau Counties. It then resumes as an expressway from California to Jefferson City. It has a 15-mile-long concurrency with US 63 for 12 miles (19 km) from Jefferson City. From just west of Linn to Union, the road is 2 lanes. After passing through Linn as Main Street, it shares short concurrencies with Highways 89 and 19 between Osage and Gasconade Counties and intersects with Highway 47 in Union. After going through this city, U.S. 50 is routed along Interstate 44 up to Sunset Hills and then it heads east and merges with U.S. Routes 61 and 67. These three concurrent U.S. routes stay this way until after the interchange with Interstate 55. Then U.S. Highways 61 and 67 split off, leaving U.S. 50 to merge with Interstate 255 to cross the Mississippi River on the Jefferson Barracks Bridge in St. Louis.
