Hayaward Baker, Inc. (HBI) worked on the construction of the Seaside Way Pedestrian Bridge in Long Beach, California. The bridge connects the Long Beach Convention Center and Long Beach Performing Arts Center. This project received ENR's 'Best of the Best 2018' award in the Landscape/Urban Development category.

The bridge consists of six continuous spans and two cantilever ends supported by seven, 5-ft-diameter reinforced concrete columns in turn supported on 7-ft-diameter drilled shafts. It is constructed 25 ft above an at-grade roadway Site soils were sands with a very shallow water table.

For each at-grade drilled shaft location along the bridge alignment, HBI utilized 96-in.-diameter oversized construction safety casing (CMP) to stabilize the upper portion of the 84-in.-diameter drilled shaft. Drilling of the shaft to tip elevation at 45 ft below working grade was accomplished under polymer slurry. A reinforcing cage was placed for the full length of the pile and concrete tremied in to displace the slurry and complete the pile.

Hayward Baker, Inc. completed the project safely and on time despite limited work areas in this congested, high traffic location.
