Woodrow Bean Transmountain Drive

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]

Purple Heart Memorial Freeway

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.

Joe Battle Boulevard

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.

César Chávez Border Highway

After meeting the El Paso Ysleta Port of Entry, the highway curves northwest, following the Mexican 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.

Border West Expressway

The newest segment of Loop 375, the Border West Expressway, passes from downtown through a narrow gap between UTEP and the Mexican border. Between Interstate 10 and US Route 85 (the CanAm Highway), the route is elevated above railroad tracks.^[3] The segment serves as an alternate route to I-10 to relieve traffic congestion in and around downtown El Paso.^[4]

The project, originally known simply as the Loop 375 Extension, was approved in September 2007.^[5] The Border West Expressway name was adopted in 2014.^[3] Construction began in 2015 with a planned completion date of late 2017, but this was pushed back to 2019.^[6]

The extension was planned as a four-lane toll road built by the Texas Department of Transportation (TxDOT) with tolls collected by the Camino Real Regional Mobility Authority (CRRMA).^[7] However, when the extension opened for traffic on October 3, 2019, no tolls were collected.^[8] CRRMA planned to start charging tolls once given approval by TxDOT,^[9] but this did not occur. Eventually, on October 26, 2023, CRRMA and TxDOT agreed to remove tolls on the expressway altogether, as CRRMA determined the road would have operated at a loss if tolls were implemented. The road is set to be integrated into the State Highway system once the tolling equipment is removed.^[10]

• 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.
• January 2019 view of another segment, from the Porfirio Diaz Street–Interstate 10 interchange ramp. The border fence, Rio Grande, and Ciudad Juarez are visible under the new elevated roadway.
