Interstate 12 is an express alternate to Interstate 10 between Baton Rouge and Slidell, for travelers making long-distance east-west trips through Louisiana.  While Interstate 10 is bowing south to wrap around the south side of Lake Pontchartrain, giving itself the purpose of serving New Orleans, Interstate 12 stays to the north heading straight east-west.  It occupies the latitude shared with the sections of Interstate 10 to the east and west.  The west end is at Interstate 10 in Baton Rouge.  From there, Interstate 12 proceeds east through Hammond, where it crosses Interstate 55.  Past Hammond, it runs along the north side of Lake Pontchartrain, through Covington.  The eastern end is soon after, at a four-way interchange with Interstate 10 and Interstate 59, which starts off toward the northeast.  (Interstate 10 occupies the southern and eastern legs of the interchange.)  That terminal interchange is near Slidell, Louisiana, about six miles from the Mississippi border. US Route 190 follows closely along Interstate 12 for the freeway's entire existence.

My photo for Interstate 12 comes from the interchange with Louisiana Route 1077.  This is on the west side of Covington, Louisiana.  The signage depicted faces south to northbound cars on the state route, indicating the location of the eastbound onramp to Interstate 12.  The photo was taken in January 2019 as part of the third Gulf Coast trip.
