Utah State Route 35

Utah State Route 35 is a state highway in northern Utah, running roughly east–west from the Lehi area through the Uinta Range foothills to Francis. The route connects rapidly growing communities in Utah County with recreational destinations near Heber City and serves regional traffic between I‑15 and US‑189. SR‑35 traverses a mix of suburban, agricultural, and forested landscapes, linking municipal centers, reservoirs, and trailheads used by residents and visitors from Salt Lake City, Provo, and the Wasatch Front.

Route description

SR‑35 begins near the Wasatch Front corridor at an interchange with I‑15 in the vicinity of Lehi and advances eastward through the city of Alpine, intersecting with US‑89 and passing close to historic sites tied to Brigham Young. The highway climbs toward the American Fork Canyon drainage and skirts the northern shore of Deer Creek Reservoir, providing access to recreation areas used by visitors from Salt Lake City, Sandy, and Orem. SR‑35 continues through mixed farmland and rangeland adjacent to Alpine Loop Scenic Byway spurs, crossing tributaries of the Provo River and offering views toward the Mount Timpanogos massif and the Uinta National Forest. Approaching Heber Valley, the route descends into Wasatch County and terminates at US‑189 near Francis and the resort town of Heber City, facilitating connections to Park City, Deer Valley Resort, and winter recreation areas such as Snowbasin and Alta. Along its corridor SR‑35 intersects local arterials that serve Thanksgiving Point, Utah Valley University, and commuter corridors feeding I‑15 and US‑189.

History

The alignment that became SR‑35 traces early wagon and mail routes used during the Mormon pioneers period and the territorial era of Utah Territory. Formal designation of a state road along this corridor occurred in the early 20th century as part of statewide improvements influenced by the Good Roads Movement and federal funding initiatives such as the Federal Aid Road Act of 1916. During the Great Depression, New Deal programs including the Civilian Conservation Corps and the Works Progress Administration contributed to roadwork and bridge construction in the region connecting Lehi, Alpine, and Heber City. Post‑World War II growth along the Wasatch Front and the rise of automobile commuting prompted state highway upgrades during the administrations of governors like Herbert B. Maw and Calvin L. Rampton. In the late 20th century, SR‑35 saw realignments and resurfacing funded through state transportation budgets and federal highway programs under the oversight of the Utah Department of Transportation. Recent decades have brought improvements coordinated with local governments including Utah County and Wasatch County to accommodate suburban expansion from Lehi and Provo and increased recreational travel to the Wasatch Range and Uinta Range.

Major intersections

The major intersections along SR‑35 include its western terminus at I‑15 near Lehi; junctions with US‑89 near Alpine; connections to county routes serving Highland and American Fork; crossings of local roads that provide access to Deer Creek Reservoir and Deer Creek State Park; and the eastern terminus at US‑189 near Francis and Heber City. These nodes link to regional destinations including Park City, Salt Lake City, Provo Canyon, and recreational corridors leading to Provo River trailheads and irrigation infrastructures associated with the Jordan River basin and Provo River Project developments.

Traffic and usage

Traffic volumes on SR‑35 vary seasonally and by segment, with commuter peaks near the Lehi and Alpine areas driven by residents traveling to employment centers in Silicon Slopes, Provo, and Salt Lake City. The corridor also carries substantial recreational traffic bound for Deer Creek Reservoir, Heber Valley, and ski resorts such as Park City Mountain Resort and Solitude Mountain Resort, particularly during winter and summer holiday periods aligned with events like the Sundance Film Festival and summer festivals in Provo. Freight and service vehicles use SR‑35 to reach agricultural operations near Wasatch County and to support construction projects tied to the expansion of communities such as Lehi, Highland, and Eden. Traffic monitoring by the Utah Department of Transportation shows year‑over‑year growth trends consistent with population increases in Utah County and tourism growth tied to Utah Office of Tourism promotions.

Future projects and improvements

Planned projects affecting SR‑35 focus on safety improvements, pavement rehabilitation, shoulder widening, and drainage upgrades coordinated by the Utah Department of Transportation in partnership with Utah County and Wasatch County. Proposals tied to regional transportation plans from bodies such as the Wasatch Front Regional Council and the Mountainland Association of Governments contemplate intersection upgrades to reduce congestion near US‑89 and I‑15 ramps, pedestrian and bicycle accommodations linking to trails maintained by the Utah Division of Parks and Recreation, and environmental mitigations to protect watersheds feeding the Provo River. Funding sources under consideration include state transportation appropriations, federal Surface Transportation Block Grants administered by the Federal Highway Administration, and local bonds endorsed by municipalities like Lehi and Heber City. Long‑range scenarios evaluated by planners also examine the impacts of continued growth in the Silicon Slopes employment center, expanded transit connections such as Utah Transit Authority services, and potential resilience measures for extreme weather events influenced by climate trends monitored by agencies like the National Oceanic and Atmospheric Administration.
