Brodsly, David. LA Freeway. Berkeley: University of California Press, Eventually, a route through the North Creek Valley was picked, between Bothell and Woodinville, leading eventually to multilevel intersections and dense industrial development there, and even a new University of Washington campus.
The Wayne Golf Course and Valhalla remain untouched. By , work was moving rapidly, with connections made at the intersection of what was then called Primary State Highway No. But it was already clear that the roadway, planned to handle traffic for 20 years, would not be adequate for long. By , the state was scouting for a parallel route for I, with a map showing an additional proposed freeway running through Maple Valley, Newcastle and Lake Hills before connecting to Highway at Bridle Trails.
Studies continue today about whether to build such a route, commonly known as Interstate , with latest concepts placing it somewhere east of the Sammamish Plateau. Year by year, I, and the conditions it operated in changed along with it. In , it was carrying 5, vehicles a day; the present count at the intersection with Highway is nearly 40 times that number — more than , vehicles daily.
Within a few years after it was opened, the carefully designed interchange had become one of the trickiest and most congested in the region, and by the s it had to be rebuilt. A new flyover ramp leading traffic from onto northbound opened in And while it was an engineering accomplishment when it opened in , a section of elevated I through Renton, known as the "S curves" because of its shape, required rebuilding in the s and s.
The new section was finished in after 22 homes were removed. I also was affected by an abbreviation no one had thought of in the s: HOV. Plans for high-occupancy-vehicle lanes began appearing in , when the state Department of Transportation announced it would take five to seven years to build 15 miles of HOV lanes from Southcenter to Interstate 5. In , the final sections from Bothell to Lynnwood were finished. By , walk-on ridership during the…. Ferry Construction King County.
