                        TRANSPORT CORPORATION OF AMERICA
                         REPORTS SECOND QUARTER RESULTS

MINNEAPOLIS, MINNESOTA, JULY 17, 2003 - TRANSPORT CORPORATION OF AMERICA, INC.
(NASDAQ: TCAM), today announced revenues for the second quarter 2003 of $65.6
million, compared with 2002 second-quarter revenues of $69.0 million, a decrease
of 4.9 percent. Second quarter's net loss was $837,000 or $0.12 per diluted
share, compared with 2002 second quarter net income of $208,000, or $0.03 per
diluted share.

Michael Paxton, Chairman, President and Chief Executive Officer, commented, "We
are clearly disappointed with our second quarter results. A soft freight
environment during much of the second quarter, especially in a number of our key
geographical markets, significantly reduced available miles. Despite these
challenges, we continued our efforts to drive productivity and network balance,
reducing our deadhead miles from 11.8 percent in 2002 to 10.6 percent in 2003.
Our administrative productivity improved, with our revenue per non-driver
employee increasing by 7.4 percent in the second quarter over the previous year.
In addition, our revenue per loaded mile improved for the second consecutive
quarter as a result of rate increases and improvement in freight mix."

"The soft freight environment negatively impacted our utilization during the
quarter," Paxton continued, "reducing miles per tractor by 1.9 percent and
revenue per tractor by 1.4 percent over 2002 levels. In addition, we experienced
increased insurance and claims costs in the quarter relating to claims
settlements. Our accident frequency rate remains at historically low levels, and
we continue to implement programs to improve safety and reduce claims expense."

"We also maintained our focus on improving the balance sheet," Paxton noted.
"For the thirteenth straight quarter, Transport America has reduced its overall
debt position. During the second quarter of 2003, we paid down $6.7 million of
debt, bringing our total outstanding debt balance to $60.0 million."

YEAR-TO-DATE RESULTS

For the six-month period ended June 30, 2003, Transport America announced
revenues of $132.7 million, compared with 2002 year-to-date revenues of $135.1
million. Net loss for the six-month period was $1.4 million, or $0.19 per
diluted share, compared with a 2002 net loss of $19.3 million, or $2.67 per
diluted share.

Results in 2003 include a non-cash benefit of $167,000 after taxes, or $0.02 per
share, for a change in estimate related to the impairment of revenue equipment
recorded in 2002 and non-cash charge of $64,000 after taxes, or $0.01 per share,
for a change in accounting principle relating to environmental disposal costs on
tires. Results in 2002 include a non-cash asset impairment charge of $2.5
million after taxes, or $0.35 per share, for asset




impairment charges related to plans to dispose of approximately 260 tractors
without guaranteed residual values and 500 trailers in excess of the Company's
needs. Results in 2002 also include a non-cash goodwill impairment charge of
$16.7 million after taxes, or $2.31 per share.

OUTLOOK

Looking ahead, Paxton commented, "While the first half of 2003 has seen soft
demand for freight, we are cautiously optimistic that we will see increased
demand during the second half of 2003. In addition, we are aggressively pursuing
new freight opportunities. During the second quarter, we were awarded over $8
million in annualized new business from one customer that we expect will ramp up
early in the third quarter. We also believe we will be able to maintain some of
the early success we have experienced in achieving rate increases. In addition,
we recently initiated a new cost reduction program we expect will allow us to
identify and achieve significant cost savings as we go through the second half
of 2003."

10:00 a.m. Central Time. The Internet broadcast can be accessed at the Company's
