Interstate 110 (Texas)

Interstate 110 (I-110) is a 0.92 mi auxiliary Interstate Highway in El Paso, Texas, extending from I-10 south along U.S. Highway 54 (US 54), then turning west, and finally turning south into Mexico. I-110 provides access from I-10 to the Bridge of the Americas, which spans the Rio Grande to connect with Avenida Abraham Lincoln in Ciudad Juárez, Mexico. I-110 is currently the only auxiliary Interstate to connect directly with Mexico, and one of only two to connect to an international border, the other being I-190 in New York.

Route description
The highway begins at its southern terminus, the beginning of the Bridge of the Americas, which spans the Rio Grande and connects to Federal Highway 45. The route proceeds north, crossing over all six lanes of Loop 375 (Cesar E. Chavez Border Highway) and divided Delta Drive. Immediately after passing over Delta Drive, the highway's truck lanes split off and pass through a specialized customs area. The roadway's mainlanes proceed northward through the El Paso BOTA Port of Entry, where each vehicle is searched by the U.S. Border Patrol. The route continues north, traveling parallel to Chamizal National Memorial, before splitting off and reaching an interchange with US 62 (East Paisano Drive). The road bends eastward, traveling past several houses and businesses, before it reaches an incomplete interchange with US 54 (Patriot Freeway). From the interchange, I-110 proceeds north as a complex series of three-level entrance and exit ramps, unofficially referred to as the "Spaghetti Bowl". The ramps merge into US 54, and the roadway continues concurrently with it, passing over Lincoln Park before reaching its northern terminus, an interchange with I-10. US 54 continues northward from the interchange.

The Texas Department of Transportation (TxDOT) lists I-110's official length as being 0.891 mi, while the Federal Highway Administration (FHWA) lists it as being 0.92 mi. I-110 is the shortest Interstate in Texas. The Interstate is almost entirely unsigned; the only signage showing its existence is on two overhead signs just beyond the El Paso BOTA Port of Entry going northbound.

History
I-110 was officially designated as a route from I-10 to the Bridge of the Americas in 1967. The interchange at US 62 was completed in 1970. By 1972, the interchange at US 54 had been completed. The overpass at State Highway 20 (SH 20) and the interchange at I-10 were completed in 1973.
