Westward Expansion A San Antonio, Texas, USA story
Cities
Pronounced urban/suburban expansion is visible on the west edge of the city. The main outer loop highway visible in all images is 1604. New residential areas push westward to expand beyond this outer loop into the surrounding forests. Also noticeable is the addition of Highway 151, which runs from east to west. New retail development can be seen as the small bright white shapes just north of where this highway intersects with 1604. Can you also spot where a golf course was built in this time period? How about the progression of other new roadways?
