Flying through the air
A girder for the new South 216th Street Bridge in SeaTac, WA flies through the air with the greatest of ease thanks to a pair of construction cranes.
The girders for the bridge are 168 feet long, weighing in just under 96 tons each.
In June 2023, contractor crews set six girders for the southern half of the new bridge. Another 10 girders will be set in 2024 after the existing bridge is demolished to make room for the northern half of the new bridge.
Crews are also setting 24 girders immediately north of South 216th Street for a new northbound I-5 flyover ramp that will connect to the new SR 509 Expressway.
The new bridge and flyover ramp are just two improvements that are part of the Puget Sound Gateway Program's SR 509 Completion Project.
