Construction on a water quality project will begin Sept. 3 on Northeast Highway 99 between Northeast 68th Street and Northeast 78th Street. The project includes installation of stormwater treatment basins and vaults to improve water quality in Cougar Creek. The project also includes downstream improvements to the stormwater collection and treatment system.

Northeast Highway 99 will remain open during construction; however, drivers should expect delays and lane closures. The outer travel lanes and bike lanes will be closed in work areas, as needed, both northbound and southbound. Drivers should watch for flaggers and signage directing traffic through the construction area. Access to local businesses will remain open.

Construction is expected to be completed sometime during the winter of 2023-2024. Construction start and end dates are weather dependent. Project information and schedule updates can be found at clark.wa.gov/public-works/highway-99-water-quality-retrofit.
