Caltrans District 7 Headquarters, California


Think of a state office building in downtown Los Angeles as a canvas on which to create significant architectural design. When the California Department of Transportation, or Caltrans, committed to building a replacement headquarters for their 7th district, they gave the canvas to architectural firm Morphosis.

Thom Mayne, who founded Morphosis,recently won the prestigious international Pritzker Prize for architecture. Working with him on the District 7 headquarters was project architect Pavel Getov and project manager Silvia Kuhle. Contracting was handled by the Clark Construction Group.

The Market Street Bridge is a historic landmark spanning the Ohio River, connecting Steubenville, Ohio and Follansbee, West Virginia. It is a steel suspension bridge spanning a length of 1,794 feet and built in 1905. After hearing reports that the bridge might be closing, city councils on both sides of the river got together and petitioned for the bridge to be repaired and beautified.

Work begins in 2010 cleaning and repairing the bridge’s steel structure, applying a penetrant sealer, as well as special calcium sulfonate paint.
