Carretera estatal 58 de Oklahoma

La carretera estatal 58 (abreviada SH-58 ) es el nombre de dos carreteras estatales en Oklahoma . Una de ellas recorre 72,7 millas (117,0 km) desde Medicine Park hasta la línea divisoria entre los condados de Blaine y Custer cerca de Hydro , ^{[ 1 ]} y la otra conecta la US-270 / 281 / SH-3 / 33 con la línea divisoria estatal de Kansas, con una longitud de 105,9 millas (170,4 km) . ^{[ 3 ]} La sección norte tiene una ruta secundaria con letra , SH-58A.   

La SH-58 formaba parte originalmente de la US-164. Cuando la US-164 fue desmantelada en 1930, un tramo de la carretera en el condado de Major que quedó sin designación pasó a ser la SH-58. Desde entonces, la carretera se ha extendido tanto hacia el norte como hacia el sur. Con la designación y extensión del tramo sur, la SH-58 está presente en cinco condados de la parte occidental del estado.

La SH-58 se puso en servicio por primera vez entre el 1 de marzo de 1930 y el 1 de diciembre de 1931. Su trazado original era mucho más corto que el de la carretera actual. En 1931, la SH-58 era un camino de tierra que se extendía desde la SH-8 al este de Fairview hacia el norte hasta Ringwood. ^{[ 5 ]} Antes de recibir la designación SH-58, este tramo de carretera formaba parte de la US-164 y de la primera SH-13 . ^{[ 6 ]} El 29 de mayo de 1930, la AASHO aprobó una extensión de la US-60 que sustituyó a la US-164. ^{[ 7 ] [ 8 ]} Cuando la US-60 sustituyó a la US-164 en la zona, se modificó su trazado hacia el oeste, tal como lo sigue actualmente. El tramo de la antigua carretera estadounidense que ya no tenía designación pasó a ser la SH-58. ^{[ 5 ]}

Throughout the 1930s, SH-58 was expanded in both directions. The first addition to the highway came during the first half of 1932, when the highway was extended north to Helena. No east–west highway existed at this point yet, leading to a spur end.^[9] The highway was extended to the south, replacing SH-44, to Canton on March 29, 1937.^[10][11] SH-58 was extended north to the Kansas state line sometime between April 1937 and April 1938.^[12] This final extension brought SH-58's northern section to its present-day termini, and no major changes to the northern section have occurred since.

SH-58's southern section was first established on October 16, 1945, when SH-54 was given a new alignment further to the west; its old alignment was redesignated as SH-58.^[13] The original routing of SH-58's southern section began at US-277 in Cyril, continued west through Apache, and turned north at the present-day western intersection with SH-19. SH-58 continued north along its present alignment to Hydro, where it ended at US-66/SH-1.^[14]

In 1955, SH-19 was established through southern Caddo County, taking over the east–west section of SH-58. Thus, SH-58 was truncated to where it intersected with SH-19 (the present day western end of their concurrency).^[15] SH-58 was extended to its present terminus north of Hydro the next year.^[16] The highway was further extended in 1964, bringing the southern terminus to its present location near Medicine Park.^[17] No further routing changes have occurred since then.^[4]

SH-58 has one spur, SH-58A, a 5.33-mile (8.58 km)^[2] route in Blaine County. The route begins at SH-58 near Longdale, and travels to Canton Lake. There, the highway runs across the dam impounding the lake. The highway then turns south and ends at SH-51 west of Canton.^[4]
