Freese and Nichols developed a two-phase design and construction project to replace an existing water bridge with a dual tub reinforced concrete structure. The structure was designed with cast-in-place components as well pre-cast components. Incorporated into the design were two 180-foot-long battered gabion wall earth retaining structures, a bridge designed to support tracked dredging equipment, an upstream water "chute" and a downstream hydraulic jump structure.
Construction was separated into two components: temporary bracing/support component to stabilize the existing structure through the 2011 irrigation season and the final construction phase between October 2011 and March 2012 (replacing the existing structure).
