Dominie Creek

Dominie Creek bridge lies on ancestral territory where Caltrans and Tolowa Dee-ni’ Nation worked together to replace the old dilapidated box culvert structure. The finished bridge has an emblem of spawning salmon at each abutment barrier wall which was inspired by the locations salmon and trout spawning.

Challenge

The challenge was to complete the bridge replacement with minimal natural resources disturbance on the development area. Ductal® Infrastructure Accelerated was used in conjunction with adjacent box girders design to provide a fast rehabilitation of the bridge.

Optimisation

Caltrans Department of Transportation utilized the properties of Ductal® UHPC to utilize within precast connections. Many small span bridges that use the adjacent box girders are present in the state and need replacement in the near future. The use of Ductal® Infrastructure Accelerated, minimizes the amount of time spent on site and allows for staged construction to maintain limited traffic in the area. The solution allowed to gain 12ksi in 12 hours when heat was applied for accelerated curing.
