SR 39 Connector begins at an intersection with the SR 39 mainline southeast of Florence Marina State Park, south-southwest of Omaha. It travels to the southeast, crossing over a northeastern arm of the Walter F. George Lake. Then, it curves to an eastern orientation and travels through Providence Canyon State Park. The route then travels to the east-southeast. Just before entering the city limits of Lumpkin, it intersects US 27/SR 1 (Martha Berry Highway). At its intersection with Florence Street, the connector curves to the east and meets its eastern terminus, an intersection with SR 1 Connector (Chestnut Street).
