SR 92 follows the general route of the Monte Cristo and Everett Railroad, which was completed in 1894 and later paralleled by a local road.

Recently, the Washington State Department of Transportation (WSDOT) has completed small projects to improve SR 92, including two roundabouts within the first two miles of the highway's western terminus and a roundabout/truck bypass of Granite Falls.

The highway travels into the western outskirts of Granite Falls and turns north at a roundabout with 96th Street, which forms a short spur route along the former alignment of SR 92.

The first project was completed in October 2005 and replaced a culvert on Stevens Creek with a bridge,[18] located between Lake Road and 99th Avenue,[19] 0.46 miles (0.74 km) east of the SR 9 intersection.

[1] A second project completed in September 2006 widened the highway and improved intersections between SR 9 and 84th Street (Getchell Road).

[24][25] A truck bypass of Granite Falls and SR 92 has been completed; the 2.1-mile (3.4 km) long route runs through Indian camps, where artifacts have been uncovered.

Three roundabouts were installed on the bypass: at the SR 92, 100th Street and Jordan Road intersections, which decrease heavy vehicle traffic through Granite Falls.
