From the Cedar/Lake Washington Salmon Recovery News for August 2021:

Fall is coming and salmon will be returning to streams and rivers throughout King County to spawn. The annual Salmon SEEson program will run from late August through November, promoting self-guided salmon viewing sites as well as some hosted events (stay tuned!). If you decide to visit a self-guided site near you, please remember to: plan ahead, practice social distancing, wear a mask, leave no trace, and contribute to an inclusive experience for all. Check out the Salmon SEEson website for more information on self-guided and viewing opportunities!

Image: This shows an excavator with an attachment called a hydraulic breaker. It is being used to break up the pavement that will be removed. This is one of two areas that will have a dewatering header pipe, which collects the water that is pulled from the ground. This will dry out the excavation area which is below the water table, to allow installation of the new culvert.

Starting August 16th there will be a minimum 3-week closure of East Lake Sammamish Parkway at Ebright Creek (located approximately at 125 E Lake Sammamish Parkway). The closure will allow for completion of the new water and sewer systems and installation of the box culvert. Additional notifications and message boards will be posted and a signed detour will be in place. View detour plan here.

Drivers should expect delays and consider using alternate routes.

Image: The closure area is relatively small, but through-access will not be permitted. This simplified detour map shows the primary detour route for vehicular traffic. There will be local access only on either side of the closure area. Drivers should consider alternate routes that may work better for their destination. During the closure, bicyclists and pedestrians will be able to detour around the closure using the East Lake Sammamish Regional Trail.
