2023 Eastern Region Chip Seal

This project will preserve multiple state routes across Pend Oreille, Stevens, Lincoln and Adams counties in Eastern Washington.Chip sealing is the application of a special protective wearing surface to an existing pavement. Included in the chip seal project will be constructing bituminous surface treatment (BST), planning bituminous pavement, crack sealing, hot mix asphalt (HMA) paving, pavement repair, and prelevel, removing existing overlay from bridge decks, bridge deck repair, placing waterproof membrane, crushed surfacing top course, centerline rumble strips, fog seal, pavement markings, guideposts, traffic control and other work.

During construction, travelers can expect a reduced speed approaching the work zone and intermittent single-lane closures. Users can expect one-way alternating traffic with flaggers at times. Please remember to slow down in work zones and watch for road crews.

This project includes chip sealing on the following routes:SR 20 – Spruce Canyon Road to S. Fork Mille Creek Road (6.17 miles)SR 21 – I-90 to Cannawai Creek (36.1 miles)SR 25 – Fruitland to US 395 (42.97 miles)SR 28 – Grant County Line to Lamona (24.13 miles)SR 31 – Metaline Falls to Canada (12.72 miles)SR 231 – Reardan to Fisher Road (8.92 miles)SR 292 – Springdale to Loon Lake (5.91 miles)US 395 – Columbia River to Boyds (6.81 miles)

These roads were last chip sealed 10 or more years ago between 2008 and 2013. The roadway surfaces have reached the end of their surface life and are due for pavement repair. This project will rehabilitate the roadway and preserve it for years to come.

Project is anticipated to begin in spring of 2023 and last through summer. During construction, multiple crews and routes will be worked on simultaneously as various pieces of the chip seal are performed.

There are no related maps or drawings.
