Business Loop I-8 - Winterhaven

1.9 miles in length, Business Loop I-8 (Winterhaven Drive) to Winterhaven is a locally maintained route connecting Interstate 8 with the unincorporated community north of Yuma, Arizona. Winterhaven Drive lines part of Historic U.S. 80 between CR S-24 (Araz Road) west and CR S-24 (Picacho Road) east across the Yuma Main Canal. Old U.S. 80 followed Quechan Road southeast to the Ocean to Ocean Highway Bridge spanning the Colorado River and Arizona border.
The business route at Winterhaven seamlessly links with Business Loop I-8 south into Yuma, Arizona. State maintenance commences along Winterhaven Drive through the diamond interchange (Exit 172) with I-8. Classified as Route 8U, Business Loop I-8 extends 0.40 miles south to the Colorado River and N 4th Avenue in Yuma.
Located in southeastern Imperial County, Winterhaven sits at an elevation of 130 feet. The 2000 Census placed the population at 529 people and by the 2020 Census only 192 lived in the unincorporated community. The population number however increases during the winter months with snowbirds.
