The SR 542/SR 547 Kendall intersection has a history of collisions and has been identified by WSDOT as an area that would benefit from safety improvements. As traffic in this area continues to grow, the conflicts and merge issues that have made access difficult will only increase.
During construction the north spur of SR 542 will be closed so the roundabout can be built. Stop signs will be added on SR 542 to create a three-way stop at the junction of SR 542 and SR 547. SR 547 will be limited to one-lane near the roundabout location 24 hours a day during construction, with flaggers directing traffic.
