TBI helps transportation agencies across the nation move people more efficiently. We build, refurbish, and upgrade landmark bridges, complex highway systems, railways, and urban mass transit systems. Utilizing traditional and alternative delivery methods, TBI has constructed more than $4 billion in transportation projects during just the last five years.


TBI’s ability to drive tunnel in all types of ground, as well as our extensive marine construction expertise, makes us an excellent partner for agencies that deal with the movement of water and wastewater. We build large- and small-diameter pipeline tunnels in deep or shallow ground and beneath large bodies of water, with award-winning results.
