The City of Sammamish has announced a slew of infrastructure upgrades that will affect traffic patterns in the coming months, as detailed on their official website. Among the projects is a boardwalk repair on SE 24th between 236th Ave SE and 234th Pl SE, which caused single-lane closures and directed traffic with flaggers from August 6-9, as per the City of Sammamish.

Commuters should also note that starting today through Friday there will be minimal traffic disruptions due to a stormwater pipe CCTV inspection and cleaning that involves sporadic single-lane closures, as per the city's notification, the work is essential for assessing and ensuring the integrity of the city's stormwater infrastructure but it will be done with minimal disruptions, keeping inconveniences to the city's residents at a low.

In addition, work continues on ADA barrier removals, which began July 14 and are set to conclude by August 22. This necessary project includes replacing damaged sidewalk panels along 228th Avenue SE/NE and upgrading pedestrian curb ramps at certain intersections, aiming to enhance pedestrian safety and access for those with disabilities.

Tree maintenance activities carried out by Asplundh should not go unmentioned, as these ongoing efforts contribute to the overall safety and maintenance of our city's thoroughfares, specifically remarking on the work near the 4800 block of Issaquah-Pine Lake Road SE. Lastly, a water main installation project that kicked off in August and continues through to December along Sahalee Drive East, where motorists can expect minor delays due to active traffic control measures in place, the installation is being undertaken by Northwest Sammamish Water & Sewer. It is guided by the city's commitment to improving infrastructure for its citizens.
