Nearly two dozen residents from the Timberline and Hidden Ridge subdivisions protested Tuesday over the possibility that Sammamish might consider removing the 42nd St. barricade, a controversial idea that previous city councils rejected.
The barricade has safety and design issues that residents say make removing it dangerous.
City officials previously considered it as a way to improve connectivity and traffic flow in the far northwest corner of the city and to relieve traffic pressure on SR202 from Sahalee Way.
Sammamish’s new Intelligent Transportation System (ITS), intended to speed traffic along the main arterial, 228th Ave., through the City, has generated enough complaints that a refresh is likely, officials say.
The ITS is intended to synchronize traffic lights based on traffic demand through the entire corridor. The problem: left turn signals don’t “trip” as often as before, sometimes leading to three full traffic light cycles before left turns are permitted, according to some City Council Members at a recent Council meeting.
Complaints appearing on social media point to longer cross street red lights, even when there is little or no traffic on 228th.
On other occasions, cross streets have the green even when there has been no traffic.
City transportation officials are well aware of the problems.
