Sundial Bridge at Turtle Bay, Redding, California, USA
The Sundial Bridge was the first steel inclined pylon, cable-stayed bridge in the U.S.

This 220 m (722 ft.) long cable-stayed pedestrian bridge, with a 126 m (413 ft.) main span, was designed by the Spanish architect, Dr. Santiago Calatrava.

The most prominent feature of the bridge is a striking sculptured inclined steel pylon 58 m (191 ft.) high, which leans due north and acts as a sundial interpreted on the circular plaza at the tower base. Locked coil cable-stays support a trussed tubular steel superstructure with a unique translucent glass deck. The bridge connects the Turtle Bay Park, Museum and Amphitheater with the Redding Arboretum.

Buckland & Taylor provided erection engineering for both the pylon and the deck. Detailed modeling of the complex stiffened double walled steel tower was required to assess stability and strength during both tower and deck erection phases. 3D cambers were required to achieve the desired final structure geometry and stay forces.

Buckland & Taylor also provided value engineering and re-designed the foundations and substructure to reduce the overall costs of the structure.
