EXHIBIT 1


                            AMENDED RIGHTS AGREEMENT

         This Amendment No. 2 to Rights Agreement is entered into effective this
17th day of January, 2000 by and between Transport Corporation of America, Inc.,
a Minnesota corporation (the "Company") and Norwest Bank Minnesota, N.A., (the
"Rights Agent").

         WHEREAS, the Company and the Rights Agent entered into that certain
Rights Agreement dated as of February 25, 1997, as amended on June 29, 1998 (the
"Agreement") and now desire to amend Section 1(a) of the Rights Agreement.

         NOW, THEREFORE, in consideration of the premises and other good and
valuable consideration, Section 1(a) of the Rights Agreement is hereby amended
in its entirety as follows:

                  (a) "Acquiring Person" shall mean any Person (as such term is
         hereinafter defined) who or which, together with all Affiliates (as
         such term is hereinafter defined) and Associates (as such term is
         hereinafter defined) of such Person, without the prior approval of a
         majority of the Board of Directors, shall be the Beneficial Owner (as
         such term is hereinafter defined) of voting securities having fifteen
         percent (15%) or more of the then voting power of the Company, but
         shall not include the Company, any Subsidiary of the Company, any
         employee benefit plan of the Company or of any Subsidiary of the
         Company, or any entity organized, appointed or established by the
         Company for or pursuant to the terms of any such plan; provided,
         however, that if a Person is the Beneficial Owner at the close of
         business on the date of this Agreement of fifteen percent (15%) or more
         of the voting power of the Company, such Person shall not be deemed an
         Acquiring Person unless and until such Person acquires any additional
         Common Stock in any manner other than pursuant to a stock dividend,
         stock split, recapitalization or similar transaction that does not
         affect the percentage of outstanding Common Stock beneficially owned by
         such Person. Notwithstanding the foregoing or the last sentence of this
         Section 1(a), no Person shall become an "Acquiring Person" as the
         result of an acquisition of Common Stock by the Company which, by
         reducing the number of shares outstanding, increases the proportionate
         number of shares beneficially owned by such Person to fifteen percent
         (15%) or more of the then voting power of the Company then outstanding;
         provided, however, that if a Person shall become the Beneficial Owner
         of fifteen percent(15%) or more of the then voting power of the Company
         then outstanding by reason of shares purchased by the Company and
         shall, after such share purchases by the Company, become the Beneficial
         Owner of any additional Common Stock of the Company, then such Person
         shall be deemed to be an "Acquiring Person." Notwithstanding the
         foregoing, if a majority of the Continuing Directors then in office
         determines in good faith that a Person who would otherwise be an
         "Acquiring Person", as defined pursuant to the foregoing provisions of
         this paragraph (a), has become such inadvertently, and such Person
         divests as promptly as practicable a sufficient number of shares of
         Common Stock so that such Person would no longer be an Acquiring
         Person, as defined pursuant to the foregoing provisions of this




         paragraph (a), then such Person shall not be deemed to be an "Acquiring
         Person" for any purposes of this Agreement. Notwithstanding the
         foregoing, the parties to that certain Stock Purchase Agreement of the
         Company dated May 20, 1998 relating to the acquisition of North Star
         Transport, Inc. who will be receiving the Company's Common Stock
         pursuant to such Stock Purchase Agreement (the "North Star
         Shareholders") shall not be deemed an Acquiring Person until such time
         as they become the Beneficial Owner of seventeen percent (17%) or more
         of the voting power of the Company and references to "fifteen percent
         (15%)" in this Agreement shall be deemed to refer to "seventeen percent
         (17%)" when applied to the North Star Shareholders. Further,
         notwithstanding the foregoing, US Freightways Corporation ("USF") and
         Zeus Acquisition Corporation ("Merger Sub"), who are parties to that
         certain Agreement and Plan of Merger by and among USF, the Company and
         Merger Sub, dated January 17, 2000 (the "Merger Agreement"), and who
         will be receiving irrevocable proxies from certain shareholders of the
         Company as specified in the Merger Agreement shall not be deemed an
         Acquiring Person as a result of their entering into such voting and
         proxy agreements.




         IN WITNESS WHEREOF, the parties hereto have caused this Amendment No. 2
to be duly executed and attested as of the day and year first above written.

         This Amendment may be signed in one or more counterparts, each of which
shall be deemed an original but all of which together will constitute one and
the same instrument.
