Route description

For its entire length Route 90 is a two-lane highway. It passes through rugged areas and the roadway is both very hilly and very curvy.

McDonald County

Route 90 begins an intersection with Route 43 in the extreme northeastern part of the city of Southwest City. (From that intersection northbound Route 43 heads north towards Seneca and southbound Route 43 heads briefly west, then south through Southwest City and then on towards Maysville and Siloam Springs, both in Arkansas. Also from that intersection, County Road 9097 heads south, then southwest to end at Route 43.)

From its western terminus, Route 90 proceeds east for nearly two miles (3.2 km) before turning north-northeast and connecting with the north end of Route MM at a T intersection. (Route MM heads southeasterly towards the unincorporated community of Pack and then on to the Arkansas state line.) Route 90 continues north-northeasterly for just over one mile (1.6 km) before turning easterly again. After about three miles (4.8 km) Route 90 enters the city of Noel and immediately connects with the south end of Route TT at T intersection in a part of the city that was formerly the unincorporated community of Spring Valley.

Approximately one-half of a mile (0.80 km) further southeast Route 90 reaches its western junction with Missouri Route 59 (Route 59) at a T intersection on the south bank of the Elk River. (Route 59 heads north along North Cliffside Drive to cross the Elk River and then on towards Lanagan.) Route 40 proceeds southeast, concurrently with Route 59 for roughly one-third of a mile (0.54 km) before reaching its eastern junction with Route 59 at another T intersection.
