Texas State Highway Loop 375

Loop 375 begins clockwise at an intersection with I-10 near Canutillo. Heading east, the highway enters and passes through the Franklin Mountains State Park and the Fort Bliss Castner Range before leaving at Northeast El Paso, where it meets US 54. The highway passes through Northeast El Paso before entering Fort Bliss.

The section through Franklin Mountains State Park includes many road cuts which expose outcrops of Precambrian rocks, which are some of the oldest in Texas.[2]

After entering Fort Bliss, the highway bypasses Biggs Army Airfield to the north and east, and meets Spur 601 east of the airfield, before leaving at an intersection with US 62/US 180 in Southeast El Paso.

After leaving Fort Bliss, the highway passes through Southeast El Paso, heading south through residential neighborhoods, before curving southwest to meet I-10 at a stack interchange. Continuing southwest, the highway passes through more neighborhoods before meeting the El Paso Ysleta Port of Entry.

After meeting the El Paso Ysleta Port of Entry, the highway curves northwest, following the Mexico-United States border along the Rio Grande. Heading into downtown, the highway intersects US 54 at an interchange, passing unter the El Paso BOTA Port of Entry. The highway continues west into downtown, ending at US 62/US 85 Paisano Drive in downtown.

From downtown, the most recent part of Loop 375, the Border West Expressway, passes through the narrow gap between UTEP and the Mexican border, elevated above the railroad tracks between Interstate 10 and US Route 85 (the CanAm Highway).[3] The project is intended as an alternate route to I-10 to relieve traffic congestion in and around downtown El Paso.[4] Funding and construction of the project began in September 2007.[5] The highway is proposed to be a four lane toll road.[6] In March 2018, the original completion date estimate of late 2017 was pushed back to May 2019.[7] The new expressway opened for traffic on October 3, 2019, without tolls initially although it is intended to be a toll road.[8]

Originally described as a Loop 375 extension, the project was named as Border West Expressway in 2014.[9] On completion, signs show it as part of Loop 375.

  A panoramic view from Sun Bowl Drive at the University of Texas at El Paso, toward the nearby residential neighborhood of Ciudad Juárez, Chihuahua, Mexico, about 350 m away. This pass full of transportation arteries is the "Paso del Norte" after which El Paso is named, the route of the Camino Real de Tierra Adentro (royal road of the interior land) from Mexico to Santa Fe. In this narrow valley are the Interstate 10 freeway, the under-construction (in August 2018) Border West Expressway, the Union Pacific and BNSF railroads, US Highway 85 (Paisano Drive, CanAm Highway), a border fence, the American Canal, and the Rio Grande. The new expressway will mostly occupy space above the railroad tracks.

  January 2019 construction progress. Note the new ramp behind the UTEP Miners' pickaxe sculpture. This ramp and elevated roadway will carry the westbound lanes of the new expressway; the eastbound lanes are at grade, on the far side of the train tracks.
