In Oklahoma the auxiliary interstates for Interstate 44 are both in Tulsa. Providing a bypass for Tulsa traffic is Interstate 244 , which travels along the western and northern sections of the city. This highway leaves I-44 at Exit 236 and travels west and then south to rejoin I-44. Less than three miles of Interstate 444 join I-244 with US 64.

In Oklahoma City Interstate 235, which is just over five miles in length, joins I-35/I-40 to I-44. Interstate 240 departs I-40 at Exit 165 and travels west for 16 miles and ends at Exit 116 of I-44. This highway provides a southern alternative route to bypass Oklahoma City.

Interstate 5 has three auxiliary highways in the state of Oregon. Interstate 105 is four miles long and joins I-5 In Springfield to OR 99. Interstate 205 connects Tualatin in Oregon with Salmon Creek in Washington. I-205 departs I-5 at Exit 288 in Oregon and rejoins it at Exit 9 in Washington.  Providing a bypass of four miles for I-5 in Portland is Interstate 405.
