Q: It is beyond me why the traffic light on Southeast Issaquah-Fall City Road and 247th Place Southeast has to work like a normal light. There probably are 500 cars coming down Issaquah-Fall City for each that leaves the development at 247th. So why not time the light to stay green for traffic on Issaquah-Fall City except when a car approaches?
A: Good news: Come Monday, there should be a new signal at the intersection with a video-detection system to keep the light green for drivers on Issaquah-Fall City unless traffic approaches from elsewhere.
Workers will be there Monday and Tuesday to review and adjust the signal as needed, King County spokeswoman Linda Thielke said.
The county had noticed the backlog you point out, said Norton Posey, road services supervising engineer. So when the Issaquah School District began building on the south side of Issaquah-Fall City opposite 247th Place Southeast, the county’s traffic-engineering staff required that the district install a temporary vehicle-detection system to improve traffic flow. The new signal makes the change permanent.
Crews also have widened the intersection to lengthen or add left-turn bays and add a right-turn lane from Issaquah-Fall City Road into the school.

Recently a reader asked why the state transportation department doesn’t put down temporary tape to mark highway lanes when crews remove striping during construction. The reader pointed out that ruts left in the road from the removal can confuse drivers about where the lanes actually are.

Melanie Coon, a department spokeswoman, wants to emphasize that the state takes this concern seriously, is searching for solutions and is working with contractors to make sure they thoroughly remove old striping and minimize rutting.
“This is a challenging issue because pavement stripes are intentionally durable and difficult to remove,” Coon said. “The only way to completely eliminate evidence of the old stripes is to resurface the roadway, which can be costly and disruptive.”
Coon said the state also is trying new technologies to minimize rutting.
Bellevue: Main Street will close from 7 a.m. to 6 p.m. between 112th Avenue and 116th Avenue tomorrow so crews can stripe the new pavement and do other post-paving work.
