Utah State Route 157 (SR-157) is a state highway in Carbon County in the U.S. state of Utah. Spanning just over 5miles, it connects Helper and Spring Glen with Kenilworth to the northeast.
State Route 157 begins on US-6/US-191 at the Poplar Street/Hill Street interchange in the city of Helper.[1] From there the route travels east 0.2miles along Poplar Street before turning south onto South Main Street. The route then continues south 1.2miles along South Main Street (which becomes North Spring Glen Road) toward Spring Glen, parallel to US-6/US-191, before turning east onto Kenilworth Road (initially 4500 North). The route then travels east-northeast along Kenilworth Road about 3.3miles to Kenilworth, turning north onto Main Street for about 0.2miles, which then turns back to the west for the last 0.2miles, ending at Main Street and 1st Avenue.[1]
State Route 157 was established in 1933 as connecting what was then SR-8 (now US-6) between Helper and Spring Glen with Kenilworth.[2] In 1953, the state legislature designated State Route 244 in 1953 as a loop off US-6 (then also US-50) in Helper, running along Poplar Street and Main Street. The west end of SR-157 was extended north to SR-244 in Helper in 1961.In 2013, SR-244 was removed from the State Highway System, but the section of the former state route along Poplar Street (from US-6/US-191 to South Main Street) was added to SR-157. The result is the current alignment of SR-157 (south from Helper to Kenilworth road, thence northeast to Kenilworth).[2] [3]
The entirety of the former SR-244 designation, which includes the Poplar Street segment of modern SR-157, remains signed as U.S. Route 6 Business.
