Project description: Sound Transit Central Link’s South Boeing Access Road to South 154th Street light-rail project includes construction of .65-mile of at-grade guideway and 4.22 miles of elevated guideway. Included are track, handrails, systems integration components and drainage provisions. Photos courtesy Sound Transit A nearly 380-foot-long steel truss is being used to form the elevated guideway. The elevated guideway includes long-span bridge structures over Interstate 5 just south of the Boeing Access Road bridge and the Duwamish River. The work also includes one station with a park-and-ride, roadway intersection, and roadway corridor modifications with curbs, gutters and sidewalks, drainage, utility relocations, landscaping and site restoration. Columns to support the elevated guideway are being built along the state Route 518 freeway at the rate of over two per week. Construction is moving east from the station site at International and Southcenter boulevards. Along I-5, workers are clearing land and installing a temporary access road. Construction equipment will use this road to install foundations for the columns that support the elevated guideway. An additional access point to the construction area will be built at the undeveloped South 146th Street right of way off of South 51st Street. PCL Construction has built columns to support the future station and track way at the site of the Tukwila International Boulevard station and park-and-ride lot. The firm has also assembled the huge yellow gantry that is used to erect the precast concrete segments for the elevated guideway. Elevated guideway construction began in December 2005.
