Trailer Bridge Joins U.S. EPA SmartWay Transport Partnership.

JACKSONVILLE, Fla. -- Trailer Bridge, Inc. (NASDAQ Global Market: TRBR), a provider of integrated trucking and marine freight service to and from all points in the lower 48 states and Puerto Rico, today announced that it has joined the SmartWay Transport Partnership, an innovative voluntary collaboration between the U.S. Environmental Protection Agency (EPA) and the freight industry designed to increase energy efficiency while significantly reducing greenhouse gases and air pollution.

"I am pleased to welcome Trailer Bridge to the SmartWay Transport Partnership," said Margo T. Oge, Director of EPA's Office of Transportation and Air Quality. "They join the Partnership with a commitment to increase fuel efficiency and make freight-related environmental improvements."

"Joining the SmartWay Transport Partnership fits with the much cleaner environmental footprint we offer shippers for freight moving from the mainland to Puerto Rico," said Trailer Bridge Chairman & CEO John D. McCown. "While not currently a component of the SmartWay program, the greater fuel efficiency and much cleaner fuel associated with our tug/barge vessels translate into 4 to 6 times fewer emissions per cargo unit compared to the self-propelled vessels now serving Puerto Rico. Trailer Bridge's customer relationships are often driven by our more cost-efficient transportation system, but this environmental edge is becoming increasingly important for companies concerned about their environmental footprint. In the future, I expect that shippers who are members of the SmartWay Transport Partnership will be able to take credit for both the superior environmental performance of Trailer Bridge's trucking and vessel operations."

As a SmartWay Transport Partner Carrier, Trailer Bridge has committed to:

* Measure the environmental performance of its tractors

* Identify goals to improve the environmental performance of its tractors

* Encourage shippers to consider participation in the Partnership

* Track company performance to meet these goals

* Assist in the establishment of a marine category in the Partnership by participating in EPA sponsored workshops, and measuring the environmental performance of our vessels
