Due to a special Joint Meeting of Congress taking place in the Capitol on Wednesday, April 29, the U.S. Capitol will be closed to tours until approximately 12:30 p.m. on that day.

The Treaty of Guadalupe Hidalgo, approved for ratification by the U.S. Senate in 1848, set the terms for ending the Mexican War. Mexico agreed to cede more than half its territory to the United States for $15 million. A new, 2,000-mile border between the two countries was to run along the Rio Grande and Rio Gila to the Pacific Ocean with a boundary commission from each country surveying and marking its location. Congress authorized the Army Corps of Topographical Engineers to conduct the survey for the United States.
