San Antonio.
Freeways across the Alamo City.

San Antonio grew around the river, and its early irrigation works are still part of the landscape. Mission residents used acequias—irrigation channels—to carry river water by gravity to fields, and the Espada Aqueduct carried water across a creek.

The missions still belong to daily life as well as history. Four of the Spanish colonial missions south of downtown remain active Catholic parishes, and nearby communities carry family histories tied to them. The city’s food culture comes from the same long mix, with Indigenous roots, Mexican influence, European arrivals and later generations adding to the table. UNESCO recognized San Antonio as a Creative City of Gastronomy in 2017.

The military is another presence on the map. Joint Base San Antonio includes Fort Sam Houston, Lackland, Randolph and Camp Bullis, with work that ranges from medical care and recruit training to flight training and cybersecurity. Brooke Army Medical Center at Fort Sam Houston serves military patients and also treats civilian emergency patients, so the base system is part of the region’s everyday infrastructure.

By the Census Bureau’s July 2025 estimate, San Antonio had about 1.55 million residents, making it the seventh-largest city in the United States. The wider San Antonio-New Braunfels metropolitan area had about 2.81 million. That city-versus-metro distinction matters on a road map because many daily trips begin or end beyond the city boundary.

Loop 1604 shows how that growth reaches the freeway system. TxDOT’s North Expansion covers 23 miles from Bandera Road to I-35, with plans to widen the corridor from four lanes to ten, including a high-occupancy vehicle lane in each direction. The San Antonio photos in this archive give that current work some background: downtown double-deck freeways, north-side pavement before later widening, and earlier views of roads that still shape how the region moves.
