When the
Cache Valley was settled and developed in the 19th century, the north–south road through the eastern part of the valley connected all the towns, including
Hyrum,
Providence,
Logan,
Hyde Park, and
Smithfield. Later, when Logan's Main Street was extended north and south, it bypassed Providence, Hyde Park, and the newer communities of
Millville,
River Heights, and
North Logan to the west. This more direct route became the main state highway through the area in the 20th century, carrying
SR-1 (
US-91) north of and
SR-101 (now
SR-165) south of Logan. The state legislature designated two routes in 1969 that served the areas east of Logan's Main Street, following in part the old road from the 19th century.
State Route 238 began at SR-165 in
Nibley, and headed east on 200 South into Millville, then north on that city's Main Street, becoming Providence's 200 West. It jogged east on 100 South (changed to 100 North in 1970 to remove traffic from the city center) to 100 West, and then continued north into River Heights on its 600 East (numbered to match Logan's grid). Finally, it turned west on River Heights Boulevard (changed to 600 South in 1970 to avoid hills), north on 400 East into Logan, and west on 300 South to end at US-91.
State Route 237 continued north from Logan, beginning at
US-89 (400 North) and 600 East, and following 600 East, 1000 North, and 800 East through North Logan. In Hyde Park, the name changed to 250 East, and SR-237 turned west on 200 South, north on Main Street, and west on Center Street to a northern terminus at US-91. Other than the 1970 changes to SR-238 requested by the cities, the next change came in 1981. The part of SR-237 on Logan's 600 East and 1000 North, having "more the characteristics of a city street", was given to the city, and in exchange a same-length segment of 1400 North, a four-lane
arterial connecting US-91 to SR-237, became a new
State Route 239. This left SR-237's south end at 800 East and 1000 North, where
SR-288, a peripheral route around
Utah State University, went both east and south. Portions of SR-288 were given to the city and university in 1992, and SR-237 was extended south three blocks on 800 East (former SR-288) to 700 North, a city street. A western bypass of Logan on 1000 West was planned at least since the 1970s as a local road, It was modified in 1945 to use Airport Road directly from US-91, and was removed from the state highway system in 1969.
Construction project Project Description: The project follows the recently completed environmental document to improve the safety and capacity of 10th West/SR 252 and 2500 North and bring the route up to state standards. On 10th West, work will include widening the roadway to five lanes from US 91 to 300 North (including the Logan River Bridge) and a new west-side frontage road between 600 South and 200 South. Traffic signals and turn lanes will also be installed at 10th North and 14th North. On 2500 North work will include widening to five lanes from 600 West to Main St., plus two left turns onto Main St. As part of the project, the contractor will also close the north side of the 1100 West/US 91 intersection, as discussed during the environmental process. UDOT has selected Staker Parson Company as the general contractor. For background on the entire project, see the completed environmental document at Final Environmental Study. ==Major intersections==
