The segment between Sanderson and Jacksonville , Florida, was the first part of Interstate 10 to open in 1961. The last section to be completed in Florida ran from Kynesville to Oakdale south of Marianna .

In Texas, nine sections of Interstate 10 have been built since 1959. One focus of the construction work was closing the gap between San Antonio and Houston , which took place in 1962. The peak of the construction work was from 1970 to 1980. The first section in Texas was the I-10 between El Paso and Van Horn and the last section was the bypass of Fort Stockton.

The last stretch of Interstate 10 to be completed was the Papago Freeway in downtown Phoenix , which opened to traffic on August 10, 1990. This section includes the Deck Park Tunnel, which is symbolically the last section of the I-10.

By Hurricane Katrina was in 2005 twin-span bridge destroyed between New Orleans and Slidell, the eastern Lake Pontchartrain spanned. But unlike the Escambia Bay Bridge near Pensacola in Florida, which was damaged by Hurricane Ivan in September 2004, Interstate 12 and the Lake Pontchartrain Causeway can still be used as alternative routes in Louisiana . The bridge was repaired and used for normal traffic until July 2010. Construction of a new bridge began in mid-2006 and opened to traffic in April 2010 with restrictions. The construction work and the demolition of the old bridge should be completed by mid-2012.
