 This area (Eagle Drive) is now the central core of Mont Belvieu's residential area hosting multiple subdivisions and many "mom & pop" stores.Another core was developed south of the original city along Texas State Highway 146 north of Interstate 10; this core is based mostly on commercial services for Interstate 10 travelers hosting multiple hotels, fast food restaurants, and gas stations.The two cores are connected by the city's old location (now dubbed "the hill") which consists mostly of petrochemical company offices and cement slabs of the old city.
