Interstate 12

Interstate 12 travels 86.65 miles wholly within the state of Louisiana. Providing a regional bypass of the Greater New Orleans area, I-12 connects the capital city of Baton Rouge with I-55 at Hammond and I-10/59 at Slidell. The freeway is also a commuter route from Baton Rouge east to Denham Springs and Walker in Livingston Parish.

Work on I-12 from U.S. 61 (Airline Highway) in Baton Rouge and Hammond was ordered on July 6, 1965.¹ The section of I-12 between LA 63 at Livingston and Interstate 55 at Hammond opened to traffic on February 15, 1970.² The segment between Livingston and Albany was already completed by December 1969, but not yet opened as routing traffic off U.S. 190 to I-12 and back via LA 63 and LA 43 would increase the distance and result in traffic jams due to the detours.¹
