Route 20 is a 31.609-mile (50.870 km) state highway in Lafayette and Saline counites in Missouri, United States, that connects Missouri Route 13 (Route 13) northwest of Higginsville with U.S. Route 65 Business (US 65 Bus.) in Marshall.
Route description
For nearly its entire length Route 20 is a two-lane road that passes through rural farmland and crosses several small creeks and valleys.
Lafayette County

Route 20 begins at a modified T intersection with Route 13 northeast of Higginsville in Lafayette County. The intersection is also the northern teriminus of Misssouri Route 13 Business (Route 13 Bus.). From its western terminus Route 20 runs concurrently with Route 13 Bus. to enter Higginsville and run along the south edge of the Confederate Memorial State Historic Site. On the southeast corner of the Historic Site, Route 13 Bus. turns to head south while Route 20 makes a left turn at another T intersection. Promptly after its junction with Route 13 Bus., Route 20 connects with the south end of Missouri Route 213 (which heads northerly along the east edge of the Historic Site to end at U.S. Route 24 [US 24], west of Dover).[2][3]
Immediately after its junction with Route 213, Route 20 leaves Higginsville and continues northeasterly for about 1.7 miles (2.7 km) before turning east. Just over one mile (1.6 km) farther east, Route 20 connects with the south end of Route F and the north end of Bonanza Road. (Route F heads north to Dover and Bonanza Road head south to Higginsville Reservoir.) Continuing east for 2 more miles (3.2 km), Route 20 connects with the south end of Route BB[a] and the north end of Route V, north of Corder. (Route BB heads north to end at US 24 and Route V heads south to quickly pass through Corder and then on to end at the west end of Route AA.)[2][3]
After continuing east for about 4.6 miles (7.4 km) Route 20 crosses Missouri Route 23 (Route 23) northeast of Alma. (Route 23 heads north to US 24, east of Waverly, and heads south toward Concordia.) Approximately one-fifth of a mile (0.32 km) east of its junction with Rotue 23, Route 20 connects with the north end of Route W (which heads south towards Alma). Route 20 then continues east for another three miles (4.8 km) before leaving Lafayette County.[2][3]
Saline County
Promptly after leaving Lafayette County and entering Saline County, Route 20 passes through the city of Blackburn.[b] About one mile (1.6 km) east of Blackburn Route 20 connects with the south end of another Route BB[a] at another T intersection. (This Route BB heads north to US 24 in Grand Pass.) Approximately 2.7 miles (4.3 km) farther east Route 20 connects with Missouri Route 127 (Route 127) at yet another T intersection. (Route 127 heads south towards Sweet Springs.) From the western Route 20 / Route 127 runs concurrently for one mile (1.6 km) before Route 127 splits off at a T intersection. (Route 127 heads north to pass through Mount Leonard before ending at U.S. Route 65, west of Malta Bend.[2][3]
About two and a half miles (4.0 km) east of its eastern junction with Route 127, Route 20 connects with the south end of the northern segment of Route EE at one more T intersection. Approximately one and a half miles (2.4 km) farther east the concurrent Route 20 / Route EE connects with the southern end of County Road 419 (CR 419) and the southern segment of Route EE. (While CR 419 heads north, Route EE heads south towards Interstate 70 / U.S. Route 40 [I-70 / US 40].) Approximately one mile (1.6 km) farther east, Route 20 curves to proceed north for about one more mile (1.6 km) before curving to proceed east once again. In the middle of the last curve Route 20 connects with the south end of Route Z at a T intersection on the southern edge of the small unincorporated community of Shackleford. (Route Z heads northerly to pass through Shackleford.)[2][3]

East of Shackleford, Route 20 proceeds easterly for just over two miles (3.2 km) before entering the city limits of Marshall. Within Marshall Route 20 continues east along West Arrow Street for roughly two and a half miles (4.0 km) before crossing U.S. Route 65 (Lexington Avenue / US 65) on the western edge of the residential area of the city. (US 65 heads north towards Malta Bend, Waverly, and Carrollton and heads south towards I-70 / US 40, Sedalia, and Springfield.) About 1 mile (1.6 km) farther east Route 20 reaches its eastern terminus at US 65 Bus. (Odell Avenue) at a slightly askew intersection. (From that intersection US 65 Bus. heads north to run briefly concurrent with Missouri Route 41 / Missouri Route 240 before ending at US 65. US 65 Bus. heads south to end at US 65. Also from the intersection East Arrow Street continues east for about five more blocks.)[2][3]
History
Route 20 was one of the original 1922 highways. Its eastern terminus was originally at Huntsville at Route 10 (now US 24). Its western terminus was originally in Kansas City at Route 1. In 1926, the section west of Waverly became part of US 24 and the section from Waverly to Marshall became part of US 65.[4] In 1933-1934, Route 20 was extended west on its current alignment to Higginsville. This section had been planned as Route 96 (Odessa to Marshall) in 1922, but was soon dropped from the state highway system. In 1934/1935, the section from Glasgow to Huntsville became part of Missouri Route 3 when that route was extended. The next year, the section from Marshall to Glasgow became part of Route 240.[5]
