Missouri Route 102

unincorporated community of Airline Acres.^[1] The road begins to travel south through the community and farmland.^[3] It intersects County Road 334 (CRD 334) and CRD 422 less than one mile (1.6 km) from its western terminus. The route intersects Missouri Route 80, which leads to East Prairie. Route 102 then crosses over a spillway ditch near CRD 528, and it turns southeastward at CRD 521.^[1] The road borders the Ten Mile Pond Conservation Area, and access to the area is provided by Route VV via CRD 518.^[4] North of the eastern terminus of CRD 521, the road travels south briefly and intersects CRD 521 again before turning east. The road meets Route YY, a short route that leads to Route FF, at a three-way junction before traveling southeastward. Just east of Big Oak Tree State Park, the road to the entrance of the park, Route RB, intersects Route 102 and CRD 508. Route 102 then travels south to its intersection with Route A at Three States, where it travels eastward from that point. About two miles (3.2 km) later, the route travels to its eastern terminus at Route 77 and CRD 510 in Dorena.^[1] The Dorena–Hickman Ferry is located southeast of the intersection, at the southern terminus of Route 77.^[3]

Route 1A.^[5] The route was renumbered to Route 102 by 1930,^[6][7] and a project to begin the paving of gravel, which cost $96,800 (equivalent to $1,765,539 in 2023), started in April of that year.^[8] About three years later, Route 102 was renumbered to Route 4, with the project completed.^[9][10] Route 4 was then later renumbered to U.S. Route 136 in 1951.^[11]

Route 55 by 1955.^[18][19] Routes A, PP, and 102 were completely paved by one year later.^[19][20][21] By 1961, Route 102 replaced Route A from the park entrance westward.^[22][23] The route was repaved near East Prairie in 1965.^[24] Route 102 was extended south by 1994, with its new eastern terminus at Route 77 near Dorena. The road from the state park to Route 102 was given the designation of Route RB, and Route PP was replaced by Route 102. The western terminus of Route A was truncated to its intersection with Route 102 south of the state park.^[25][26]
