2012 Map of Alton

About this map

Alton and its neighboring communities in Hidalgo County reveal a landscape structured by a precise grid of mile roads and the underlying energy industry during the early 21st century. The map shows the significant footprint of petroleum extraction, with the Mission Gas Field, Sharyland Gas Field, and Oblate Gas Field distributed throughout the northern and western sections. Residential expansion is visible in the growing footprints of Palmhurst and West Sharyland, where subdivisions and smaller street networks began to fill the spaces between long-established agricultural corridors like W Monte Cristo Rd. The transportation network is anchored by a mix of historic routes, including Old Hwy 107, and modern thoroughfares like F-M 676, illustrating the transition from a purely rural economy to an increasingly suburbanized region of South Texas.
