Texas State Highway 12

State Highway 12 (SH 12) is an east–west state highway that runs from I-10 in Vidor to Deweyville on the Texas-Louisiana boundary in east Texas. The route was designated in 1959 as a renumbering of SH 235 to smooth the travel transition with Louisiana Highway 12, with which it connects.

Route description

SH 12 begins at an intersection with I-10 and US 90 on the north side of Vidor, and travels to the northeast. It travels through lightly populated country before reaching the Sabine River at Deweyville. The route continues into Louisiana as Louisiana Highway 12.

History

SH 12 was one of the original twenty six state highways proposed in 1917. It was an ambitious undertaking to construct a border-to-border highway hugging the southern Texas coast and border with Mexico, and was to be named the 'Jefferson Davis Memorial Highway.'

In 1917 the route followed present day Interstate 10 eastward from El Paso to roughly Esperanza. From there the road was proposed to go to Presidio (not built) and followed FM 170 from there to near Lajitas. It was proposed from there to hug the Rio Grande through Big Bend and towards Langtry (again, never built) where it would have met up with present day U.S. Highway 90. On US 90, the road would have gone into Del Rio and, via present day US 277, into Eagle Pass and though to Paso de Francia via present day FM 1021 and FM 1472 to Laredo. The Paso de Francia to Laredo segment was again, at the time never built. From Laredo to Pharr the road would have followed present day U.S. Highway 83. At Pharr, a spur of SH 12 would have continued east on US 83 to Brownsville. The main road went north on from Pharr on U.S. Highway 281 to Falfurrias then East on SH 285 into Riviera and north on U.S. Highway 77 towards Victoria, through to Houston on U.S. Highway 59 and finally US 90 to Orange.

Colorado State Highway 12

State Highway 12 (SH 12), also known as the Highway of Legends, in the U.S. state of Colorado is a mountainous state highway through the Rocky Mountains in southern Colorado. The route travels from La Veta through the mountains to Trinidad. It is included in the Colorado Scenic and Historic Byways system and runs through the San Isabel National Forest.

Route description

State Highway 12 begins at the junction with U.S. Highway 160 north of La Veta. It heads southward through that town before entering the San Isabel National Forest and passing through Cuchara, near the Spanish Peaks Wilderness. It then crosses Cucharas Pass into Las Animas County.

SH 12 heads through Monument Park and turns eastward near Stonewall. It then passes eastward along the Purgatoire River through Weston, Segundo, Valdez, Cokedale, and Jansen. It then ends in Trinidad at Interstate 25.

History

The route was established in the 1920s, beginning at Stonewall at SH 111 east to Trinidad and La Junta. The Trinidad-La Junta section was replaced by US 350 in 1957 and the route was paved from Weston to Trinidad in 1939. The entire route was paved by 1946. In 1954, SH 111 was changed, leaving SH 12's terminus without another state highway. In 1970, SH 12 was extended to US 160, and the segment was paved a year later. The route was designated a Colorado Scenic and Historic Byway in 1989. In August 2004, Interstate 25 was disconnected from SH 12, leaving SH 12's terminus at Nevada Avenue in Trinidad.
