Bridge Construction

Self Propelled Modular Transporters (SPMTs)

A Self-Propelled Modular Transporter is a combination of multi-axle platforms operated through a state-of-the-art computer-controlled system that is capable of pivoting 360 degrees as needed to lift, carry, and set very large and heavy loads of many types.

SPMTs are motorized vehicles that move at walking speed and are capable of carrying large structures, such as bridges, from offsite locations, positioning them precisely into final position. The SPMT then exits the site, opening the area to traffic possibly within minutes or certainly within a few hours.

What is a Self-Propelled Modular Transporter - or SPMT?

The Federal Highway Administration (FHWA) has identified reducing construction-related impacts to the traveling public as a major priority for the nation's highway program.

The use of self-propelled modular transporter (SPMT) technology provides agencies and contractors with the ultimate flexibility and speed in removing and installing bridges.
