Interblox 710 (I-710 - also known as "The 710") is a 86-mile (138 km) major north-south interstate highway over Carmen County, Bloxburg Valley. Officially known as the North Port Freeway, it passes north of North Port toward Alhambre following the course of the Los Angelox River for most of its route, although in certain parts it diverges from the river. South of SR 1 in North Port, I-710 is officially part of the Santa Catalina Freeway.
Originally known as the Los Angelox River Freeway prior to November 18, 1954, the 710 had been planned from its inception to be built north through New Robloxia, but construction of the segment from Alhambre to Bloxburg City through South Bloxburg had been delayed for several decades due to community opposition. Prior to 1983, the highway was not yet an Interstate, although it had been built to Interstate standards. Until 1964 it had been State Route 15, but changed its number to State Route 7 in the 1964 renumbering due to the existence of Interstate 15, and I-710 in 1983.
This route is part of the Bloxburg Valley Expressway and Expressway System.
