Atkinson led the design-build effort to replace the existing 1925 Warren Truss bridge with a new, wider bridge that meets today's design and construction standards. Atkinson's proposed design differed from WSDOT's concept to construct a four-span concrete bridge to the west of the existing southbound bridge. Instead, Atkinson proposed constructing a three-span, 557-foot-long steel girder bridge within the existing northbound Warren Truss bridge footprint.
 
By doing so, Atkinson eliminated the proposed southbound widening, and all retaining wall, utility relocation, ground improvement, and signalized intersection work. To accomplish this, the project team built new temporary piers and approach roadways and rolled the Warren Truss to the east for use as a temporary northbound detour. This allowed the team to maintain northbound traffic at its current capacity throughout construction.
 
In addition, the steel bridge benefits included eliminating the in-water pier and fish window schedule constraints, providing flexibility for future master plan construction, and accommodating the future levee widening.
 
The site's soil conditions consist of loose fill soils underlain by an artesian aquifer and a very thick alluvial deposit that is subject to liquefaction, lateral spreading, and settlement during an earthquake. Atkinson's large diameter drilled shafts are designed to withstand the soil and artesian water conditions and our abutment design improves global stability. By utilizing rotator-oscillator drilling methods, the project team limits the risk of vibration-induced settlement on existing structures and utilities. In addition, a web-based vibration and settlement monitoring system will immediately notify us if detrimental effects are detected.
 
The wider shoulder, lanes, and an eight-foot sidewalk will enhance bicycle and pedestrian safety.
 
Upon project completion, Atkinson removed the historic Warren Truss bridge intact for WSDOT's future use.
