Lynch Road merging onto southbound US 101
To improve the ability for drivers at Lynch Road to see oncoming northbound US 101 traffic, crews realigned northbound US 101 closer to the highway median. That reconfiguration and associated roadway striping modified the stop location for drivers and bicyclists on Lynch Road who are turning onto US 101, allowing travelers to better focus on northbound US 101 traffic. This project also built a new 1,140-foot-long acceleration lane in the highway median for drivers merging onto southbound US 101, eliminating the current need for drivers to wait in the highway median before joining southbound US 101 traffic. This enhancement will not only reduce the potential for collisions, but will help reduce congestion for Lynch Road drivers turning onto southbound US 101.  

Lynch Road merging onto northbound US 101
Crews modified the highway median by adding a 1,200-foot-long acceleration lane to northbound US 101, giving Lynch Road drivers plenty of room to reach highway speeds before merging onto northbound US 101. 

Why isn’t WSDOT building an interchange at this intersection?
No funding has been identified for a new interchange, which has an estimated starting cost of $25 million. WSDOT believes previous efforts combined with proposed improvements will help reduce the potential for collisions. WSDOT believes that as traffic volumes increase at US 101 and Lynch Road, future improvements may be necessary.
