State Route 13 (SR-13) is a state highway in northern Utah, running 32.841 miles (52.852 km) parallel to I-15 in Box Elder County from Brigham City to Riverside. Most of SR-13 is a former routing of U.S. Route 191.

Route description

SR-13 begins at an intersection with US-89 and US-91 at the south end of Brigham City and heads north through the city, then turns west at the north end of the city to intersect I-15 and I-84. It continues northwest across the Bear River through Corinne and turns north parallel to I-15 and I-84 through Bear River City. It intersects I-15 and I-84 at Elwood and continues north around the east side of Tremonton.

North of Tremonton, SR-13 continues north through Riverside and Plymouth, turning northwest to end at another intersection with I-15 near Plymouth.^[1]

History

The road from SR-1 (by 1926 US-91, now SR-90) in Brigham City north to the Idaho state line became a state highway in 1910.^[2] It was initially assigned the State Route 17 designation in the 1920s,^[3] but in 1927 the state legislature changed the designation to State Route 41.^[4] The portion south of SR-42 (now SR-102) in Tremonton became part of U.S. Route 30S in 1926,^[5] and the entire route became Utah's portion of a southern extension of U.S. Route 191 in the late 1930s.^[6] A new alignment around Tremonton and Garland was defined in 1935, with the old route becoming SR-82.^[7]

The SR-41 designation was dropped in 1962, as State Routes 1 to 5 were assigned to proposed Interstate Highways (in Utah law; the routes were never signed as such), and SR-41 was on the route of I-15, which was SR-1 under Utah law. However, since I-15 near Brigham City was almost complete, only the portion of SR-41 north of Riverside was assigned SR-1; the remainder was instead renumbered as an extension of SR-84, which had ended at Hot Springs Junction north of Ogden.^[2] Since the original proposed alignment of I-15 would have passed east of Tremonton and Riverside, this extension of SR-84 turned east at Riverside, following present SR-30 to SR-154 (Garland Road). When SR-154 was removed from the state highway system in 1969, SR-84 was extended farther east over part of it to SR-69 (now SR-38) near Collinston. Finally, in the 1977 renumbering, the part of SR-84 between Hot Springs Junction and Brigham City was redesignated US-89, and State Route 13 was created for the portion between Brigham City and Collinston.^[8]

By 1982, proposed I-15 had been moved west to its current alignment north of Tremonton, and a new SR-129 was created to connect it with Riverside along present SR-30. For continuity, SR-13 was cut back to Riverside, with the Riverside-Collinston portion also becoming SR-129. SR-13 was extended north from Riverside to I-15 at exit 392 near Plymouth in 1988, replacing what had been maintained as temporary I-15. A small realignment was made in 2008 at the SR-83 intersection in Corinne, moving SR-13 from the diagonal routing alongside the rail line to a straight north–south routing on 4800 West.^[9]
