U.S. Route 36 in Missouri runs from the Pony Express Bridge over the Missouri River in St. Joseph to the Mark Twain Memorial Bridge over the Mississippi River in Hannibal. After leaving the Missouri River valley, U.S. 36 then links major cities in Northern Missouri with Kansas City and cities in the east. From Cameron to the Illinois state line, it is overlapped with Route 110, also known as the Chicago–Kansas City Expressway. Starting in St. Joseph, it passes through the cities of Cameron, Hamilton, Chillicothe, Macon, Shelbina, Monroe City, and Brookfield. The final of US 36 in Missouri is concurrent with Interstate 72. The route passes through mostly flat, fertile, productive farmland. Even though there are some surface intersections, U.S. 36 has many grade-separated interchanges and town bypasses that suggest a future extension of I-72 west from Hannibal.
History
US 36 across Missouri parallels the route of the Hannibal and St. Joseph Railroad, which was the reason St. Joseph was selected for the Pony Express. The two towns were the second and third largest cities in the State of Missouri prior to the American Civil War. Prior to the establishment of the railroad in the late 1850s, the stagecoach route was called the "Hound Dog Trail." The road was originally Route 8 from 1922 to 1926, before being designated as US 36. Over the years some busier sections were upgraded to four lanes. On August 3, 2005, residents of Macon, Marion, Monroe, Shelby, and Ralls counties approved Proposition 36B, which excluded Ralls County from the Transportation Development District, and allowed for a 4-lane US 36 to be constructed without Ralls County's participation. In June 2010 work was completed making US 36 a four-lane highway across the entire state, saving considerable travel time.
Future
Presently I-72 ends at US 61 in Hannibal, but further lengthening is proposed by Marion County. The five-item transportation list finalized by the County Commission on February 16, 2016, added the upgrade of US 36, from the Mark TwainMemorial Bridge across the Mississippi River, to the split of US 24 and US 36 near Rocket Plaza, as a new priority. Citing potential benefits including economic development and marketing of Hannibal Lakeside Industrial Park, the Commission advocate extending Interstate 72 west approximately.
