Interstate 10 bisects Baton Rouge, 1800 miles from the highway's origin at Santa Monica, California, and 600 miles from its terminus in Jacksonville, Florida. To the East from Baton Rouge, I-12 provides a cutoff under the name West Florida Republic Highway through the Florida Parishes to the North Shore and Mississippi and beyond; I-10 proper jogs southeast to visit New Orleans. To the West, I-10 takes you over the ???? bridge to the other side of the river and then to Lafayette and Houston. The I-110 spur provides access to downtown Baton Rouge and the airport.

points to ponder What lay in the I-10 right-of-way before I-10? When was I-10 built through Baton Rouge? How do you get on I-10 eastbound from LSU campus?
