Touchdown! A new bridge girder is set
One of the first 6 girders for the new South 216th Street Bridge in SeaTac, WA is carefully placed on piers.
Each girder is 168 feet long and weighs just under 96 tons.
In June 2023, contractor crew set 6 girders for the southern half of the new bridge. Another ten 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.
