Graham Contracting submits contract bid with apparent best value for upcoming Montlake Project
We accomplished another SR 520 Program milestone today by announcing that Graham Contracting Ltd. submitted the proposal with the apparent best value for the upcoming Montlake Project. This announcement came after our team spent several weeks thoroughly reviewing the three finalists’ proposals. Read more about it in our news release. The Montlake Project is scheduled to begin construction in early 2019.
New construction schedule announced for SR 520’s Rest of the West improvements
We have a new, updated schedule for implementing the $1.6 billion of remaining SR 520 corridor improvements funded by the Legislature’s 2015 Connecting Washington transportation legislation. We are moving ahead on several key fronts that will allow us to enhance public safety and mobility by replacing aging and vulnerable SR 520 corridor structures. We call this area west of the new floating bridge the “Rest of the West.” The work kicks off in early 2019 with the Montlake Project, followed by construction of a new transit/HOV connection between SR 520 and Seattle’s South Lake Union neighborhood. Even more improvements come later. Learn more about the phased projects in this news release or check the project links on our Rest of the West webpage.
The SR 520 Bridge Replacement and HOV Program is enhancing public safety and mobility by replacing the highway's aging, vulnerable bridges and making significant transit and roadway improvements throughout the corridor. The construction program's planned improvements extend from I-5 in Seattle to I-405 in Bellevue.
