The current border was originally decided after the Mexican–American War (1846–1848). Most of the border is settled on the Rio Grande River on the border of Texas and northeastern Mexico. To the left lies San Diego, California and on the right is Tijuana, Baja California. The building in the foreground on the San Diego side is a sewage treatment plant built to clean the Tijuana River.
