The twin 'Hill Field Roads'; The Clearfield, U-193 version, is the original

HILL Field changed northern Utah forever. The large military base became the area's largest employer, dramatically increased the population of cities nearby, like Layton and brought into a lot of non-Utah natives to the area.
And, Hill Air Force Base also expanded area roads significantly.
There used to be a road, called 1800 North on its west side. This road went all the way from South Hooper, through West Point, Clinton and Sunset, climbing through what was called "the sandridge" and then dipping down and accessing Weber Canyon. This road's eastern segment was deleted when Hill Field was established, since that land was now a military base.
But, two different "Hill Field Roads" were established as the base was developed.

                       Today's U-193 as it approaches Highway 89 in Layton.

Ironically, the original Hill Field Road is the one that officially lacks that title today.
"Hill Field Road is approved by U.S. Government" was a Dec. 5, 1940 headline in the Weekly Reflex newspaper of Kaysville. Work on this road began in the fall of 1940. It left the Salt Lake to Ogden road (Highway 91) at Clearfield and went eastward 1.7 miles to the base. An overpass above the Bamberger railroad tracks was also being considered at the time.
Today, this road is more often named Utah State Highway 193 and it goes from Highway 89 on the east, all the way to West Point on the west side.

                 Hill Field Road in Layton meets U-193, the original Hill Field Road, today.

The Deseret News of Jan. 16, 1941 reported that the Layton segment of the Hill Field Road went from the South Gate of the base 2.5 miles to connect with Highway 89 in Layton. And, that the upper portion of Hill Field Road, from the South Gate to Highway 89 east was 3.5 miles long.
The roads were two land gravel roads at first and then widened to four-lane asphalt highways.
The Clearfield to Hill AFB road was roughed in by late 1941 and paved in the spring of 1942.
However, Layton's Hill Field Road, from the South Gate wot Highway 91, didn't open until Sept. 16, 1943. It is one Layton's busiest roads today and extends westward to 2200 West and Ellison Park. This road runs by many major businesses, including the Layton Hills Mall and Sam's Club. It also runs by Northridge High School and connects with I-15. Of the two "Hill Field" roads, it is the busiest of the two today.
Originally (and in 1943), the West Gate to Hill AFB in Clearfield was restricted to government trucks and vehicles only.
