Skanska Chosen by State of WA for $834M Project on I-405
Skanska signed an $834 million contract with the Washington State Department of Transportation (WSDOT) to expand and make operational improvements to 4.5 miles of the I-405 corridor in Bothell, Washington.
The purpose of the I-405, Brickyard to SR 527 Improvement Project is to expand the dual express toll lane system from south of the I-405/SR 522 interchange to the I-405/SR 527 interchange. The project includes new lanes, direct access ramps, interchange improvements, infrastructure supporting Sound Transit’s Stride Bus Rapid Transit program, and new fish passage culverts within the project vicinity.
In partnership with Skanska, AECOM will serve as the lead designer for the project, providing comprehensive design and engineering services to deliver upgrades that address traffic flow and express toll lane capacity. Construction is expected to begin in late 2023, and the new-look roadways will open to traffic in 2028.
