Project Highlights
New bridge construction 636' long, 6 span precast concrete bridge Close coordination with BNSF Railroad Placement of 58,000 CY approach fills Work performed in wetlands, environmentally sensitive areas Installation of 14 each, 4 to 6 foot diameter, 114 foot deep drilled shafts

This project is a 636’ long, 6 span precast concrete girder bridge over the extremely busy Burlington Northern/Santa Fe Railroad switchyard at the Port of Everett.

Work required close coordination with BNSF during installation of drilled shafts, concrete columns and setting of girders. 30 each, 130 foot long pre-stressed girders were installed using a tightly developed schedule to allow BNSF to move and switch railroad freight. Ron Kazen, BNSF Yardmaster commented, “Wilder’s coordination and scheduling effort for this project was the best I have ever seen by a contractor working on our property.”

In addition to working with BNSF restrictions the project was further constrained by a wetland within the limits of the project. Work methods were tailored to minimize the impacts to the wetland.

Wilder Construction worked closely with Weyerhaeuser prior to and after award to incorporated design changes to the drilled shafts, bridge drainage and waterline support systems, bridge handrails and bridge roadway configurations. These design changes resulted in significant cost savings for Weyerhaeuser while reducing impacts to the BNSF switching operations.

Major items of work included installation of 30 each. 130’ long girders, 58,000 CY of fill, approximately 1,900 CY of concrete; 1,900 LF of 12” storm; and water pipe; 1,300 tons of asphalt paving.
