Brooks Road is a critical T3 Collector linking smaller urban and rural development areas in west Spokane County to key routes of statewide significance, including US-2 and SR-904, while providing seamless connections to local road networks. This route serves a diverse mix of users—including Fairchild Air Force Base personnel, local freight carriers, agricultural operators, commercial and industrial traffic, daily commuters, and recreationalists—the corridor supports vital economic and military mobility in the West Plains region. Upgrades to this corridor complete an approximately 4-mile arterial link between the City of Medical Lake corporate limits (SR 902) and US-2.
This section of road had a failing PSC rating of 18 with 12' lanes, 2' shoulders, and an operational width of 32'. The roadway did not meet County standards and had severe cracking, rutting, potholes. The existing utility poles, culverts, and other clear zone inventory items also needed to be addressed. The roadway section including subgrade and surfacing depth was not adequate to support the high ADT that was anticipated to continue to increase with area development.
The existing roadway was pulverized. The roadway was prepared with a cement treated base, topped with Crushed Surfacing and paved with HMA. The project added 6' wide shoulders for a total width of 36', guardrails and culverts were constructed where appropriate and clear zone hazards were addressed.
