Isabel Pass (sometimes Delta River Pass)[2][3] is a 40 mile long gap[4] in the eastern section of the Alaska Range which serves as a corridor for the Richardson Highway about 11 miles from Paxson.[1] It is named after Isabelle Barnette, the wife of E. T. Barnette, who helped found Fairbanks.[5] The pass separates four regions, the Tanana Valley to the north, the Delta Mountains to the east, Copper River Basin to the south, and the Hayes Range to the west.

It is one of three highway passes of the Alaska Range, the others being Windy Pass for the George Parks Highway and Mentasta Pass for the Tok Cut-Off.
