From its southern terminus at K-4 east of Brownell, K-147 heads northward four miles (6.4 km) through flat rural farmlands then crosses into Trego County.

[3] From the county line, the highway continues north for roughly two miles (3.2 km), and intersects CC Road (RS-1979), which leads west to Cedar Bluff State Park.

The roadway continues for about 2.1 miles (3.4 km), makes a series of curves, and then crosses the bridge over Smoky Hill River and the Cedar Bluff Dam.

After crossing the dam it continues north through flat grasslands for about 4.7 miles (7.6 km) then curves west at South Road (RS-907).

The highway continues north from here through flat rural farmlands for roughly 5.2 miles (8.4 km), then intersects exit 135 of I-70 and US-40, at a diamond interchange.

[5][13][14] On June 26, 2019, KDOT closed the bridge that carries K-147 over the Cedar Bluff Reservoir spillway (Smoky Hill River).

The steel arch bridge, originally built in 1952, was closed due to safety concerns about structural deficiencies that were found during a recent inspection.
