mid 2019, work began to convert the junction with US-281 to an enhanced roundabout. The roundabout includes outer diamond shape lanes for oversized loads to bypass the roundabout. The former intersection with US-281 was dangerous as only US-281 traffic had to stop and therefore was the location of several injury and fatal accidents. Between 2002 and 2012, there were 21 accidents, resulting in one fatality. On March 4, 2020, traffic was rerouted, from a four-way stop and temporary asphalt detour, onto the permanent concrete outer roads for the roundabout. The roundabout was completed and opened up to traffic on May 22, 2020. Venture Corporation from Great Bend, was the primary contractor for the $5.2 million project. On July 20, 2020 work began on a project to reconstruct US-50 from Road E5 to a half mile east of Road F in Lyon County. The project will widen the highway to 4-lanes for one mile. Improvements also will be made at the Road E5 and Road F intersections. Koss Construction Company of Topeka is the primary contractor of the $7.8 million project. Future In May 2020, KDOT's Eisenhower Legacy Transportation Plan was announced. One project included in the statewide plan will complete the 4-lane expressway between Garden City and Dodge City. Junction list Special routes In Garden City. US-50 and US-83 each have business routes. They both start at the same place, at the junction of US-50, 83 and 400 about one mile (1.6 km) north of town. They run concurrently along the former alignments of US-50 and 83 through town to the intersection of Main Street and Fulton Street. At that point, the business routes split and Business 50 heads east to meet up with US-50, 83 and 400 east of town. US-50 once had alternate routings in Garden City and Dodge City and business routes in Dodge City and Ottawa. Former Alternate 50 in Garden City is now known as Campus Drive. Its purpose was to connect US-50 travelers to then-US-156 without having to go all the way into downtown. Its purpose was taken over by Spur US-83 in the 1970s. Spur US-83 is now the bypass around Garden City that carries highways 50, 83 and 400. Former Alternate 50 at Dodge City is now the main route for US-50. Business 50 in Dodge City was decommissioned when the US-400 bypass was built to the south and west of that
