Travel directions

At Cardwell, US 412 in Arkansas from Paragould enters the state of Missouri at the southernmost tip of the state. The road then runs a little northeast to Kennett, 25 miles away. The road then heads east to Hayti and widens to 2×2 lanes just before Interstate 55. One then crosses I-55 and US 412 becomes Interstate 155 past Caruthersville to the bridge over the Mississippi River to Tennessee. US 412 in Tennessee then continues to Dyersburg.


US 412 was not added to the US Highway network until 1982. The route has not been modified in Missouri since then. In 1976, the Caruthersville Bridge over the Mississippi River was opened.

Traffic intensities

Some 6,000 vehicles pass through Cardwell every day, dropping to 5,000 at Kennett and rising to 8,000 for Hayti. The double numbering with the I-155 also counts about 8,000 vehicles.

Travel directions

US 50 near Jefferson City.

Kansas City

US 50 lifts from Kansas onto Interstate 435, which forms Kansas City ‘s southern beltway here. It then continues on Interstate 470 to suburb Lee’s Summit, after which US 50 forms an individual freeway through Lee’s Summit, with 2×2 lanes. On the east side of Lee’s Summit, the freeway becomes a 2×2 divided highway with only major intersections being grade separated.

Central Missouri

Between the Kansas City region and the capital Jefferson City, US 50 is largely a 2×2 divided highway, with frequent grade-separated connections. The road passes through rolling countryside with scattered forest and some small towns. US 50 passes by Whiteman Air Force Base. The largest place one has to cross is Sedalia. The road is single lane between Sedalia and California. From California begins a section of freeway of 35 kilometers to the capital Jefferson City. There are some elevation changes around Jefferson City.

Jefferson City is not a large city, but quite strategically located in the middle of the state on the Missouri River. It crosses the north-south running US 54 / US 63. Near downtown Jefferson City, the freeway is interrupted by a series of traffic lights. East of Jefferson City is the US 50 part with the US 63 double numbered, this part is designed as a freeway.

East of the Jefferson City region, the US 50 is predominantly a single-lane road, this part has more forest and minor elevation changes. Most places on the route are small.

St. Louis

Already well west of the metropolitan area of ​​St. Louis, US 50 merges with Interstate 44. US 50 is routed south of St. Louis, but not entirely over freeways, between Kirkwood and Mehlville, US 50 runs on Lindbergh Boulevard, parallel to Interstate 270. The final section in Missouri takes you on Interstate 255, then crosses the Mississippi River via the Jefferson Barracks Bridge, and continues on US 50 in Illinois through the eastern suburbs of St. Louis.


According to bittranslators, US 50 was created in 1926. In 1941, the original Mississippi River bridge south of St. Louis was built, which was replaced in 1983 by the current Jefferson Barracks Bridge over which I-255 also runs. US 50 has become less important as a through route after the completion of the more northerly Interstate 70 in the 1960s. The US 50 has the advantage that it serves the capital Jefferson City.

The US 50 highway route at Lees Summit originally existed as a 2×2 main road with traffic lights, which was upgraded during the 1970s. In 1980 it was connected to the then new I-470.

The US 50 has been phased out into a 2×2 divided highway between Kansas City and Jefferson City, but this process is not yet complete. The double-lane section between Lee’s Summit and Sedalia was built in or before the 1980s. In 2011, the second carriageway was built at Lone Jack. Around 2009, a stretch of US 50 freeway opened between McGirk and St. Martin in the Jefferson City area. This was extended a little westwards to California in about 2011, but this part is not completely grade separated.

Circa 2003-2004, the US 50/63 interchange opened east of Jefferson City, including a second bridge over the Osage River. Subsequently, on September 12, 2014, a stretch of 2×2 divided highway opened over 11 kilometers between US 63 and Linn.

Traffic intensities

Up to 54,000 vehicles drive daily on the freeway around Lee’s Summit near Kansas City. Further east, the intensities gradually decrease from 18,000 to 12,000 vehicles as far as Sedalia. The section between Sedalia and California has 4,000 to 7,500 vehicles per day, increasing to 10,000 to 44,000 vehicles as far as Jefferson City. The ground section through Jefferson City handles 36,000 vehicles per day, dropping to 15,000 vehicles east of the city and mostly 2,500 to 6,000 vehicles on the single-lane section from Jefferson City to I-44, rising to 19,000 vehicles just before I- 44.
