Why TRC?

• Significant depth of staffing resources facilitates resourcing of specialized expertise and additional manpower for projects throughout the country.

• Experience with all types of project delivery mechanisms including design-bid-build, design-build and public-private partnerships.

TRC provided final design services for the viaduct portion of the Bay Bridge Temporary Bypass Structure, a $230

million design-build project in San Francisco/Oakland, CA.

TRC is developing the plans for a major rehabilitation of this 12,000’ cantilever-style truss bridge carrying US 190 over

the Mississippi River at Baton Rouge, LA.

Two twin, curved plate girder bridges (2200’ and 1100’)

were designed by TRC through mountainous terrain as part of the WV Route 10 project in

West Virginia.

TRC designed this award-winning, $7.5 million bridge that carries US 76 over the Chattooga River through two

National Forests between South Carolina and Georgia.
