Texas State Highway Loop 375

Loop 375 is a beltway that partially encircles the city of El Paso, Texas. The beltway is mostly a freeway, except for its northern section, which includes at-grade intersections. The highway passes through various areas of El Paso, funneling traffic within and around the city. The road is known locally under different names, as Woodrow Bean Transmountain Drive in the northern section, Purple Heart Memorial Freeway in the northeastern section, Joe Battle Boulevard in the eastern section, the César Chávez Border Highway in the southern section, and the Border West Expressway on the southwest section.

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.

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. The segment serves as an alternate route to I-10 to relieve traffic congestion in and around downtown El Paso.

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

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). However, when the extension opened for traffic on October 3, 2019, no tolls were collected. CRRMA planned to start charging tolls once given approval by TxDOT, 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.

History
Loop 375 was designated on January 26, 1962, from I-10 southeastward, eastward, southeastward, and southward to the Zaragosa International Bridge. On January 1, 1965, the section of FM 259 from I-10 to US 80 (now SH 20) became part of Loop 375. On April 1, 1968, Loop 375 was extended northwestward 12.5 miles, and the section to the Zaragosa International Bridge became a spur connection. On January 29, 1991, the section from SH 20 northeast to Loop 375 was also added, which when constructed, the old route of Loop 375 was to be deleted. On April 24, 2008, this section was deleted, but was restored as Spur 276 on July 31, 2008, but this was changed to Spur 16 on July 26, 2012, probably due to a reference to the old Loop 16.

Future
The Texas Department of Transportation announced plans to add toll lanes to the Border Highway portion of Loop 375 between Downtown El Paso and the Ysleta–Zaragoza International Bridge.

In 2012, construction commenced on an upgrade of the Transmountain Drive section of Loop 375. This expansion was controversial, as this section passes through the protected Franklin Mountains State Park.
