The New Bay Bridge is a large civil engineering project taking place between the years 2002 and 2013. The aim of the project was to replace two segments of the Bay Bridge vulnerable to eathquakes by a new structure designed to withstand seismic efforts.

For that project, Dextra was involved on two segments of the renovation project: the approach to Bay Bridge on the San Francisco side, and the Eastern segment from the Island of Yerba Buena to Oakland.

Dextra supplied for this project its Bartec Headed Bar systems. Headed Bars are an anchor disc mounted on the end of a rebar previously prepared for the Bartec system.

The use of Headed Bars provides an smart and compact alternative to long rebar hooks in areas where the reinforcement is particularly congested. Unlike hook bars, Headed Bars are particularly easy to install, as end anchors can just be screwed onto the reinforcement at a later stage, after the reinforcement is installed.

For the approach to the Bay Bridgee in San Francisco and the Yerba Buena Eastern Segment, Bartec Headed Bars were used for the shear reinforcing of the column foundations, as well as in the bridge hinges.

The Bartec Headed Bars solution is approved by CALTRANS, the California Department of Transportation, for all imperial bar size #3 to #18. and is also certified by the ICC-ES.
