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 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 resumes as an expressway from California to Jefferson City, has a brief distance as a main road, and picks up expressway status again. 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 two 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. It heads east and merges with U.S. Routes 61 and 67.
These three concurrent U.S. routes run this way until after the interchange with Interstate 55. 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.
History
Until 1926, US 50 in Missouri was Route 12.[2]
