State Route 13

Home » Guides » Utah » State Route 13

SR 13 originates in Brigham City from U.S. 89/91 and ends 33.14 miles to the north at the Plymouth Interchange (Exit 392) with Interstate 15. The state route from Main Street in Brigham City northwest to Corrine and Bear River City is the historic alignment of both U.S. 30S and U.S. 191. I-15/80N temporarily ended at the highway leading north through Elwood as well.

Business Loop I-15 Business Loop I-84

Within Brigham City, SR 13 followed the northern two thirds of what was Business Loop I-15/84. Most signs for the route were removed by 2018, with the exception of two assemblies along S Main Street between U.S. 89/91 and 700 South. The southern leg of the business loop coincided with U.S. 91 west from the south end of SR 13 to I-15/84 at Exit 362. The north end was the folded diamond interchange joining SR 13 with I-15/84 at Exit 365.

The southern leg of Business Loop I-15/84 to Tremonton overlaps SR 13 north between I-15/84 at Elwood and SR 102 (Main Street) at Crossroads. SR 13 continues north from there through Bear River Valley to Riverside and Plymouth. SR 13 separates with the former route of U.S. 191 to link with I-15 via 20800 North. Construction of Interstate 15 severed the old alignment of U.S. 191 north through Malad Valley.
