Although a few Amoco stations still use their former logo, most have since been converted to the BP livery. In St. Louis, Missouri, the largest Amoco sign in the world, both before and after the company's demise, still stands. It stands at the intersection of Clayton Road, Skinker Boulevard, McCausland Avenue, and Interstate 64 (near the southwest corner of Forest Park, home of the St. Louis Zoo, the Saint Louis Art Museum and other prominent attractions). It is visible up to two miles away on the interstate. Most surviving Amoco stations are kept so BP can continue holding the trademarks for Amoco and Standard.
