Uber Technologies Inc (UBER.N) and self-driving technology company Aurora Innovation Inc (AUR.O) will expand their driverless pilot program in Texas to meet increased delivery demand during the holidays.

The program will be expanded to the recently launched 600-mile commercial lane between Fort Worth and El Paso in Texas to support customers of logistics business Uber Freight as it ships goods this holiday season, Aurora said on Friday.

The companies launched their pilot program about a year ago to autonomously transport goods between Dallas and Houston.

“We’re crafting Aurora Horizon to help carriers of all sizes alleviate some of the supply-chain pressures that typically accompany (holiday season),” Aurora co-founder Sterling Anderson said.
