Online freight marketplace uShip has announced three top national less-than-truckload carriers have committed to uShip’s shipper-direct LTL spot rate marketplace.

The move by Con-way Freight, Old Dominion Freight Line and YRC Freight brings the total number of national and regional LTL carriers that are either live or coming online to uShip’s marketplace to 28, representing more than 80% of the annual volume in the $32 billion LTL market in the U.S., according to the company.

“By publishing their rates through uShip, LTL carriers can act a lot like airlines or hotels when it comes to pricing,” said Jim Bramlett, general manager of uShip LTL Freight. “They can now reach shipping customers directly with rates they control and dynamically adjust with market and seasonal conditions. This optimizes their asset utilization, accelerates growth in their most profitable segment, and maintains strong yield levels while maintaining their 3PL contracts.”

uShip says it marketplace also provides millions of small to midsize shippers not under a freight contract with a single online location to manage all their shipping, direct carrier access, instant capacity and transparent, competitive pricing.

Currently, uShip claims to have 250,000 registered business shippers with more than 35% of its total shipping volume in commercial freight.
