West Cannon CRT, operating as WestMart since its 2003 incorporation, is a Carlsbad fueling station and convenience store at 4990 Avenida Encinas, positioned at the Cannon Road intersection near I-5 Exit 48 and the Carlsbad Premium Outlets corridor. The pumps carry regular, midgrade, premium, and diesel grades alongside propane-tank exchange, and the convenience store stocks road-trip supplies, snacks, and cold beverages—a refueling stop that pairs with the exterior wash tunnel at Soapy Joe's Car Wash for drivers passing through on the Avenida Encinas automotive corridor. An on-site air pump, ATM, and large restrooms serve both passenger vehicles and commercial trucks navigating the Cannon Road freight route near The Crossings at Carlsbad. Drivers who notice a check-engine light while fueling can reach Carlsbad Auto Repair & Smog for BAR-certified smog inspections and OBD-II diagnostic scans without leaving the 92008 zip code. The station's diesel island accommodates Class 3 through Class 6 commercial vehicles, and the propane-exchange cage stocks standard 20-pound tanks rated to DOT 4BA or 4BW cylinder specifications for residential grills and portable generators.
