In the U.S. state of Utah, some state highways have been specifically designated to serve state parks and state institutions. The range of numbers from State Route 281 to State Route 320 has been used for this purpose since 1969.
State Route 282 consists of three segments named Campus Center Drive, South Campus Drive, Wasatch Drive, Medical Drive, and North Campus Drive, totaling 2.942 miles (4.735 km). The route connects the University of Utah in Salt Lake City with several points on its border: SR-186 (500 South) at Guardsman Way, University Street at 400 South, SR-186 (Foothill Boulevard) west of Wakara Way, and 100 South east of Wolcott Street. The university roads were added to the state highway system in 1935 as part of SR-186, and were split off as State Route 181A in 1962 and renumbered SR-282 in 1969.
State Route 287 connects SR-140 (14600 South) with the Utah State Prison in Draper via Pony Express Road (the west-side frontage road of I-15) and Bitterbrush Lane. It is 0.759 miles (1.221 km) long, ending at the parking lot just beyond the control gate. The route was created as State Route 187 in 1935, serving the old Sugar House Prison on SR-4 in Sugar House. In 1941 it was moved to the current location, and the route was renumbered SR-287 in 1969. I-15 was built over the former US-91 by 1971, at which time SR-287 was reconnected to the state highway system via the new frontage road and 14600 South. The portion on 14600 South became SR-140 in 1984.
State Route 292 is a 1.718-mile (2.765 km) four-part route that includes a perimeter road around the Salt Lake Community College's Redwood Campus in Taylorsville. There are three outlets onto SR-68 (Redwood Road) and one onto 2200 West.
State Route 293 includes "all roads and parking areas" within the grounds of the Utah State Capitol in Salt Lake City. This includes access from SR-186 (Columbus Street).

State Route 299 totals 1.03 miles (1.66 km), and includes all the roadways at the Utah Department of Public Safety's West Valley City Office used for driver's license tests. This office is located at the northwest corner of 2700 West and 4700 South, across the former from the Rampton Complex (SR-317), in West Valley City.
State Route 294 is a 0.383 miles (0.616 km) route that serves the Utah State Hospital in Provo. It begins east of 900 East, where Center Street curves into Seven Peaks Boulevard, and ends in front of the administration building. The route was created in 1935 as State Route 184, connecting SR-1 (then on 700 East) with the hospital via Center Street. When SR-1 was moved in 1963, SR-184 became part of SR-114, which had followed Center Street west of SR-1 (500 West). Center Street east of 500 West, including the hospital roadways, was removed from the state highway system in 1964, but in 1969 the hospital portion was restored as SR-294.
State Route 295 served the Utah Department of Public Safety's Orem Office until 2003. The route was created in 1982 but deleted in 2003, since the land had been sold and the office moved to a location with no driver's license test course.
State Route 296 begins on the north side of 700 North, west of 900 East, in American Fork, and loops around the Utah State Developmental Center for 1.424 miles (2.292 km). The route was created in 1935 as State Route 185, running east from SR-74 to the school, and extended east to SR-146 in 1941.

State Route 286 is a two-segment 1.306-mile (2.102 km) route that loops around the Ogden–Weber Applied Technology College in Ogden, with a one-way pair spurring west to SR-235 (Washington Boulevard) near that route's south end. Exits to Monroe Boulevard and North Street are not part of SR-286. It was created in 1935 as State Route 183 and originally serviced the Utah State Industrial School. It was renumbered SR-286 in 1969, while the Industrial School closed in 1983 and was replaced by the current college in 1984.
State Route 291 runs for 0.565 miles (0.909 km) from SR-203 (Harrison Boulevard) in Ogden, across from 7th Street, east to and around the Utah Schools for the Deaf and the Blind. It was created in 1935 as State Route 182, running along 20th Street from SR-1 (US-89) east to the former campus at Monroe Boulevard. In 1962 it was extended east to Harrison Boulevard (SR-39, now SR-203).State Route 183A was created in 1939 and numbered in 1945, running east on 7th Street from SR-1 to what was then the Utah State Tuberculosis Sanatorium on the east side of Harrison Boulevard. This route was deleted in 1963 as a transfer for 12th Street, which was designated SR-205, but in 1968 the roads at the old sanitorium, then a new campus of the Schools for the Deaf and the Blind, were readded as part of SR-182. SR-182 was split between SR-285 and SR-291 in 1969, with the piece on 20th Street being removed from the state highway system.
State Route 288 served the Utah State University in Logan until 2007. It was created in 1935 as State Route 188 and renumbered SR-288 in 1969. The final routing, stretching about 0.985 miles (1.585 km) from US-89 north on 1200 East and west on 1000 North to SR-237 (800 East), was deleted in 2007, simultaneously with the deletions of SR-237, SR-238, and SR-239 and creation of SR-252.
State Route 304 is a 0.086-mile (0.138 km) route in Hyrum State Park, ending at the intersection of 300 South and 400 West in Hyrum. It was created in 1972, and was initially located farther southeast, at Center Street and 500 South; this is still where the route is defined in state law.

State Route 305 served Big Sand Wash Reservoir (a former state park) until about 1989.

State Route 283 served the College of Eastern Utah in Price until 2001, running north from SR-55 (100 North) along 300 East and then looping around the college for a total distance of about 1.33 miles (2.14 km). The route was created in 1939, numbered State Route 182A in 1945, and renumbered SR-283 in 1969. The connection between SR-55 and the campus was moved from 400 East to 300 East in 1978 as part of a realignment of SR-55. In 2001, it was given te the city of Price so they could close one block of 600 North.
State Route 281 served Dixie College in St. George until 1991. It was created in 1935 as State Route 191, connecting SR-1 (US-91, now SR-34) to the college.
