Interstate 12

From Wikipedia, the free encyclopedia.

Interstate 12 (abbreviated I-12) is an intrastate interstate highway located entirely within the state of Louisiana, United States. It goes from Interstate 10 at Baton Rouge, Louisiana (map) to the intersection again with Interstate 10 and with Interstate 59 at Slidell, Louisiana ([1]). In 1993, the state legislature renamed Interstate 12 as the "Republic of West Florida Parkway".

Notes

• With major damage to the I-10 Twin Spans across Lake Pontchartrain from Hurricane Katrina, I-12 will be functioning as I-10 for the time being. On October 14, 2005 at 3:00 PM, the eastbound span of I-10 over Lake Pontchartrain was reopened to two way traffic.

• As this highway is a loop of I-10, some think that it would be better as a three-digit Interstate (810 is the only number available) instead of I-12, or this route should be the I-10 mainline (as the through route) and the existing I-10 should be a three-digit Interstate and/or extensions of Interstates 55 and 59.

• There is a good chance that I-12 will overlap I-10 between Baton Rouge, Louisiana and Houston, Texas in the future, and from Houston, Texas, I-12 will be extended along U.S. 290 to Austin, Texas at Interstate 35. With I-14 being reserved for an inland east-west corridor in the Deep South, I-12 would be the only number available for such a route.
