State Route 135 (SR-135) is a short divided state highway in northern Utah County, Utah, United States. The route spans east - west (or more accurately, northeast - southwest) for 0.726miles to connect the far northeastern part of Lindon and Interstate 15 (I-15) with SR-129 (North County Boulevard) in the southeastern part of Pleasant Grove. The majority of the route runs along Pleasant Grove Boulevard.
SR-135 is a four-lane connector road that runs through formerly agricultural area that has recently been developed commercially.
The route begins at a four-way intersection with 2800 West on the border line of American Fork and Lindon. From its western terminus, the route heads east in Lindon as 600 North for about 500feet as a four-lane road (with no median) before turning northeast and gaining its median, which it retains for the remainder of the route.
After turning northeast, SR-135 quickly reaches the diamond interchange with I-15 (Exit 275), which has been substantially landscaped (xeriscape) since its construction. As is crosses over I-15 the route leaves Lindon and enters Pleasant Grove, becoming Pleasant Grove Boulevard. Northeast of I-15, SR-135 continues northeast and the westbound lanes connect with the south end of Granite Way before the route reaches its eastern terminus at SR-129 (North County Boulevard). The roadway continues northeast towards downtown Pleasant Grove, ultimately connecting with State Street (US-89).
In 2002, a new roadway was complete in northwest Lindon and southwest Pleasant Grove. The road included a new interchange along I-15 and connected 600 North in Lindon (to the southwest) with State Street (US-89) in Pleasant Grove (at what was formerly a three way intersection with Center Street). Most of the new road was named Pleasant Grove Boulevard.[1] Four years later, with the completion of North County Boulevard (SR-129), the section of the roadway between 2800 West and North County Boulevard (SR-129) was designated as State Route 135.
