[2] SR‑113 begins at the intersection of South 3600 West/Charleston Road and US‑189 on the northeast shore of Deer Creek Reservoir on the southwestern corner of Charleston.

Immediately after leaving Charleston, the route enters the northeastern part of Deer Creek State Park and makes its first crossing over the Provo River.

(Tate Lane also provides access to the Cascade Springs area in the Uinta National Forest.)

The route also begins running along the border of Midway (to the east), until it fully enters the city, about 1,500 feet (460 m) north of the railroad tracks.

Just after entering Midway, SR‑113 crosses over the small Snake Creek, as it passes by some recently constructed residential developments to the west.

Passing briefly back into an unincorporated area of Wasatch County, the route connects with the southeast end of South Appenzell Lane, before re-entering Midway.

The route then leaves Midway, and begins curving back to an eastern direction, before reaching the north end of South 1000.

[5] In 1935, the legislature designated State Route 169, which began on US-40 one block north of the eastern terminus of SR-113.
