POWER OF ATTORNEY

Know all by these presents that the undersigned hereby constitutes and appoints each of Lisa Pate, Leigh Anne Battersby, Jason Grear, Mark A. Scudder, Heidi Hornung-Scherr, Jessica Kortum, and Cody Kofoid, signing singly, the undersigned's true and lawful attorney-in-fact to:

(1)

execute for and on behalf of the undersigned, in the undersigned's capacity as an officer, director, and/or ten percent stockholder of U.S. Xpress Enterprises, Inc. (the "Company"), Forms 3, 4, and 5 in accordance with Section 16(a) of the Securities Exchange Act of 1934 and the rules thereunder;

(2)

do and perform any and all acts for and on behalf of the undersigned which may be necessary or desirable to complete and execute any such Form 3, 4, or 5, including a Form ID, complete and execute any amendment or amendments thereto, and timely file such form with the United States Securities and Exchange Commission and any stock exchange or similar authority; and

(3)

take any other action of any type whatsoever in connection with the foregoing which, in the opinion of such attorney-in-fact, may be of benefit to, in the best interest of, or legally required by, the undersigned, it being understood that the documents executed by such attorney-in-fact on behalf of the undersigned pursuant to this Power of Attorney shall be in such form and shall contain such terms and conditions as such attorney-in-fact may approve in such attorney-in-fact's sole discretion.

The undersigned hereby grants to each such attorney-in-fact full power and authority to do and perform any and every act and thing whatsoever requisite, necessary, or proper to be done in the exercise of any of the rights and powers herein granted, as fully to all intents and purposes as the undersigned might or could do if personally present, with full power of substitution or revocation, hereby ratifying and confirming all that such attorney-in-fact, or such attorney-in-fact's substitute or substitutes, shall lawfully do or cause to be done by virtue of this power of attorney and the rights and powers herein granted. The undersigned acknowledges that the foregoing attorneys-in-fact, in serving in such capacity at the request of the undersigned, are not assuming, nor is the Company or Scudder Law Firm, P.C., L.L.O. assuming, any of the undersigned's responsibilities to comply with Section 16 of the Securities Exchange Act of 1934.

In consideration of the attorneys-in-fact acting on the undersigned's behalf pursuant to this Power of Attorney, the undersigned hereby agrees to indemnify and hold harmless each attorney-in-fact, each substitute attorney-in-fact, and each of their respective heirs, executors, legal representatives, successors, and assigns from and against the entirety of any and all losses, claims, causes of action, damages, fines, defense costs, amounts paid in settlement, liabilities, and expenses, including reasonable attorneys' fees and expenses (collectively, "Losses"), relating to or arising out of the exercise of this Power of Attorney by any such attorney-in-fact or substitute attorney-in-fact, and will reimburse each such indemnified person for all Losses as they are incurred by such indemnified person in connection with any pending or threatened claim, action, suit, proceeding, or investigation with which such indemnified person is or is threatened to be made a party. The undersigned will not, however, be responsible for any Losses that are finally determined by a court of competent jurisdiction to have resulted solely from an attorney-in-fact's or substitute attorney-in-fact's bad faith or willful misconduct.

This Power of Attorney shall remain in full force and effect until the undersigned is no longer required to file Forms 3, 4, and 5 with respect to the undersigned's holdings of and transactions in securities issued by the Company, unless earlier revoked by the undersigned in a signed writing delivered to the foregoing attorneys-in-fact.

IN WITNESS WHEREOF, the undersigned has caused this Power of Attorney to be executed as of this 9th day of June 2018.
