W. Thomas Street Pedestrian & Bicycle Overpass, SDOT
This Seattle Department of Transportation project provides pedestrians and bicyclists direct access from Lower Queen Anne to Myrtle Edwards Park in Seattle. The new bridge crosses Elliot Avenue West as well as Burlington Northern Santa Fe (BNSF) railroad tracks at West Thomas Street, in a location where 5 sets of railroad tracks previously meant a lengthy detour for both bicyclists and pedestrians wishing to safely access the park and the Elliot Bay Trail. CivilTech worked directly for the General Contractor, providing construction engineering services for the construction of the bridge, ramps, and access stairways. Specific tasks completed during construction included design of overhang formwork, falsework at Piers 1 and 6, falsework at the Thomas Street stairway, coordination with the crane operating comp any to develop a girder erection plan, and design of connection details at the bridge guardrail electrical enclosure, which are part of the integrated LED lighting on the bridge.
