Boeing Access Road over Airport Way Seismic Retrofit
Boeing Access Road is a principal arterial connecting I-5 and East Marginal Way South. It is considered regionally significant and is included on the National Highway System for access to the Boeing Company and the King County Airport at Boeing Field. The Boeing Access Road over Airport Way Bridge is the only remaining structure on the Boeing Access Road corridor that has not been seismically upgraded. This improvement would allow the entire corridor to be seismically resistant during a seismic event.
The seismic retrofit to the bridge consists of an upgrade to the east and west approach slabs on Boeing Access Road. During the construction of the approach slabs, Boeing Access Road will be reduced from two (2) lanes in each direction to one (1) lane in each direction. Daily commuters are asked to be aware of the reduction and use alternate routes during this portion of the construction project.
A majority of the construction work will be located under the bridge on Airport Way. Construction crews will be placing steel jackets around the concrete columns and will be adding strength members to the concrete girders. Traffic using Airport Way will be adjusted around the construction zone to allow construction crews access to the bridge columns without reducing traffic lanes.
Please note that traffic volumes could be higher in this area due to the closure of the West Seattle Bridge.
Lane reduction on Boeing Access Road will begin on September 30 and is scheduled to be 6 weeks. During the 6 week reduction, commuters are asked to find alternate routes and be aware of higher traffic volumes during peak commuting hours.
