Utah’s Road Story

Where did Utah’s main roads come from? 

Utah began paving its roads, in part, as a response to the Good Roads Movement. Between 1912 and 1916 the state paved a total of 36.5 miles, spread across multiple counties. [1] These early roads proved to be a learning experience for county commissioners, contractors, and city planners as they prepared for their future ambitions to construct a state highway system.[2] A few years later in 1919 and 1920, construction began on the state’s first all-paved north-south roadway system, highways 89 and 91.

Known as ‘The Arrowhead Trail,” Highway 91 was the main north-south route that connected Saint George to Salt Lake City and the Lincoln Highway. Many towns used the Arrowhead Trail as their main street before it became a paved highway. You may notice that I-15 follows the same route south from Salt Lake Cityas the previous route it did when it was just a trail for cars and buggies.

Highway 91 and Highway 89 

The road that is now known as Highway 91 started in the southwest corner of Utah. It had hard surfacing, and some sections prepared for pavement in 1919 [3]. Known as the Arrowhead Trail by automobile enthusiasts and boosters, this road stretched most of the length of the state towards Salt Lake City.[4]  

Highway 89 utilized the earlier 1916 construction to complete a two-lane paved road and by 1921 ran all the way from Smithfield to Spanish Fork (with minor gaps).[5] This highway utilized pre-existing infrastructure, running the length of most main streets in each town it passed through. 

Most construction on Utah’s oldest highways was finished by 1926. From 1916 until the 1956 Federal-aid Highway Act the placement of Utah’s highways did not change. [6]
