Fish project prompts Interstate 90 lane closures
July 17, 2012
Motorists should expect lane closures on eastbound Interstate 90 near Issaquah as crews remove a narrow culvert — a barrier to fish.
To complete the $2.8 million project, crews must work double shifts in order to wrap up construction before Aug. 31. The deadline is tied to the return of chinook and coho salmon, and steelhead, to the East Fork of Issaquah Creek.
The state Department of Transportation alerted motorists to prepare for closures through 3 p.m. July 20. Crews plan to reopen the lane for afternoon travelers and then close the lane again from July 21-27.
The project location is east of Highlands Drive Northeast and the Sunset Interchange between Issaquah and Preston.
Officials do not expect the closures to cause traffic backups. In the westbound direction, around-the-clock closures started several weeks ago.
Transportation planners envision a wider replacement to better accommodate the 25-foot-wide streambed in the area near the culvert.
The existing culvert impedes salmon and trout headed to historic rearing and spawning grounds.
