'''Route 20''' is a {{convert|31.609|mi|km|adj=on}} state highway in Lafayette and Saline counties 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=== [[File:Missouri 20 & Bus 13.jpg|thumb|left|East along Route 20 / Route 13 Bus. from the western terminus of Route 20, northwest of Higginsville]]
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 Missouri 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).<ref name="MoDOT map">{{cite MoDOT map|year=2021}}</ref><ref name="gmaps">{{google maps|url=https://www.google.com/maps/dir/39.1201834,-93.1949161/Blackburn,+MO/39.096482,-93.7512618/@39.0878665,-93.569049,11.5z/data=!4m11!4m10!1m0!1m5!1m1!1s0x87c3b80a0f06d8c3:0x4606089af0071122!2m2!1d-93.4835442!2d39.1064081!1m1!4e1!3e0?entry=ttu&g_ep=EgoyMDI1MTExMi4wIKXMDSoASAFQAw%3D%3D|title=Unitiled overview of Missouri Route 20|accessdate=November 15, 2025}}</ref>
Immediately after its junction with Route 213, Route 20 leaves Higginsville and continues northeasterly for about {{convert|1.7|mi|km}} before turning east. Just over {{convert|1|mi|km|spell=in}} 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 {{convert|2|mi|km|adj=pre|more}}, Route 20 connects with the south end of Route BB{{efn|name="route bb"|There are two Missouri Route BB's that both run north from Route 20 to end at U.S. Route 24, one in Lafayette County (which begins north of Corder) and the other in Saline County (which begins east of Blackburn).}} 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.)<ref name="MoDOT map"/><ref name="gmaps"/>
After continuing east for about {{convert|4.6|mi|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 {{convert|1/5|mi|km|spell=in|adj=pre|of a}} 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 {{convert|3|mi|km|spell=in}} before leaving Lafayette County.<ref name="MoDOT map"/><ref name="gmaps"/>
===Saline County=== Promptly after leaving Lafayette County and entering Saline County, Route 20 passes through the city of Blackburn.{{efn|Although the city of Blackburn extends into both Lafayette and Saline counties, Route 20 only passes through the part of the city that is located in Saline County.}} About {{convert|1|mi|km|spell=in}} east of Blackburn Route 20 connects with the south end of another Route BB{{efn|name="route bb"}} at another T intersection. (This Route BB heads north to US 24 in Grand Pass.) Approximately {{convert|2.7|mi|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 {{convert|1|mi|km|spell=in}} 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.<ref name="MoDOT map"/><ref name="gmaps"/>
About {{convert|2+1/2|mi|km|spell=in}} 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 {{convert|1+1/2|mi|km|spell=in}} 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 {{convert|1|mi|km|spell=in}} farther east, Route 20 curves to proceed north for about {{convert|1|mi|km|spell=in|adj=pre|more}} 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.)<ref name="MoDOT map"/><ref name="gmaps"/> [[File:Marshall-mo-ch.jpg|thumb|right|Saline County Courthouse from near the eastern terminus of Route 20 in Marshall, August 2010]]
East of Shackleford, Route 20 proceeds easterly for just over {{convert|2|mi|km|spell=in}} before entering the city limits of Marshall. Within Marshall Route 20 continues east along West Arrow Street for roughly {{convert|2+1/2|mi|km|spell=in}} 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 {{convert|1|mi|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.)<ref name="MoDOT map"/><ref name="gmaps"/>
==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.<ref name="1924MOrdmap">{{cite web|url=https://digital.shsmo.org/digital/collection/Maps/id/57/rec/5|title=Missouri's State Road System, 1924|website=The State Historical Society of Missouri|access-date=June 16, 2025}}</ref> 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.<ref>{{cite MoDOT map|year=1936}}</ref>
