We repaved SR 520 between I-405 in Bellevue and West Lake Sammamish Parkway in Redmond and constructed new, stronger, smoother concrete slabs at the ends of five bridges.
Drivers will have a smoother ride on smoother pavement. The new paving eliminates problems with wheel ruts, where water pools on the road. There will be less tire spray and less chance of hydroplaning for drivers.
New pavement will cover wheel ruts where water pools on the road. With completion of the project, there will be less tire spray and less chance of hydroplaning for drivers.
| Economic Incentive
It's important to rebuild and repave roads before they become too damaged, costly and time-consuming to replace.
New slabs of concrete on either side of concrete overpasses will last 30 or 40 years. New asphalt paving along the route will last about 15 years.
Repaving SR 520 before it breaks down further will keep traffic flowing to Eastside and Seattle job and shopping centers.
