This project page features the most recent activities on the project. For background on the project click here.

The goal of the project is to restore the Ebright Creek crossing at East Lake Sammamish Parkway. To do this, the project will remove the existing culvert pipes and replace them with a fully fish passable box culvert, with the goals of improving stream habitat and fish passage to support Kokanee salmon and other fish species. During construction, drivers can expect intermittent lane closures. Starting Monday, August 16th there will be a minimum 3-week closure of East Lake Sammamish Parkway at Ebright Creek to allow for installation of the box culvert.

Please check back for regular updates!

    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.
