 Despite improvements in the local roadways, Jumbo remains physically isolated from other communities in Pushmataha and Atoka counties.This is ironic, as the four-lane Indian Nation Turnpike was built through Impson Valley, passing just to the east of the community, and opened in 1970.It features no interchange for Jumbo, however, causing local residents to venture to Daisy on the north to enter or exit the turnpike.
