Utah State Route 142
# Utah State Route 142

State Route 142 (SR-142) is a state highway in the U.S. state of Utah. At 17.3 miles (27.8 km) long, it connects the towns of Newton, Clarkston, Trenton, and Richmond to US-91 and SR-23 in northern Cache County.

## Route description

The route starts at its intersection with SR-23 in Newton and travels about 5 miles (8.0 km) northwest to Clarkston. Here the route turns east and travels just over 12 miles (19 km) through Trenton and ends in Richmond at the intersection with US-91.

## History

The state legislature created State Route 142 in 1933, connecting SR-69 (now SR-30) at Petersboro with Newton and Smithfield. SR-142 was moved to the present route of Newton to Clarkston at SR-170 in 1941, with the old alignment through downtown Newton to Smithfield becoming SR-218.

In 1969, SR-170, which ran from Clarkston via Trenton to Richmond was absorbed into SR-142, and SR-170 was deleted. This completed the current route of SR-142 as it runs today.

## Major intersections

The entire route is in Cache County.
