Interstate 49 (I-49) is an intrastate interstate highway located entirely within the state of Louisiana in the southern United States. Its southern terminus is in Lafayette, Louisiana, at Interstate 10 while its northern terminus is in Shreveport, Louisiana, at Interstate 20.
Route description
I-49 begins its journey in Lafayette concurrent with U.S. Route 167 from I-10 to Opelousas at Exit 23. At Lafayette, motorists continuing southbound see the interstate highway change to U.S. 167 (Evangeline Thruway), a major thoroughfare taking travelers towards the heart of Lafayette. North of Lafayette, motorists on I-49 will parallel the ancient Mississippi river bed north of Carencro, and through Grand Coteau, just south of Opelousas. After leaving Opelousas, I-49 traverses the relatively flat, fertile farmlands until reaching Alexandria. From there, the highway roughly follows the Red River and Louisiana 1, bypassing the historic city of Natchitoches to the west on its way to Shreveport. At Shreveport, the highway parallels a railroad line just to the east until its terminus at I-20 southwest of downtown. HistoryThe original plans for interstate highways in Louisiana only included Interstates 10 and 20 with no connection in between. After Interstate 55 was added in the 1950s, the state considered building a toll road to connect I-10 in southwestern Louisiana and I-20 in the northern part of the state, but later rejected the idea. In the mid 1970s, The Federal Highway Administration approved an Interstate highway to run between I-10 and I-20, beginning at I-10 in Lafayette and ending at I-20 in Shreveport. The mileage was gained from mileage released from other highways the state did not build as well as 153 miles (246 km) from a supplemental reserve.2 Construction of I-49 began in the early 1980s, the first signed segment from I-10 to Washington, Louisiana opened in 1984. After several delays, most of the highway was open by the early 1990s. The entire length of the 212-mile (341 km) road was completed May 1, 1996 when a 16.6-mile (26.7 km) section of highway in Alexandria named the Martin Luther King Jr. Highway was completed. The total cost of I-49's construction was about $1.38 billion. Future
Long-term plans call for I-49 to be extended southeastward from Lafayette to New Orleans; and northward from Shreveport to Kansas City, Missouri. Construction for the extension north is already underway in southwest Missouri, northern and southwestern Arkansas, and in northern Louisiana. These plans may result in pieces of this interstate being disconnected. Once Arkansas and Missouri finish the Bella Vista Bypass, mentioned below, both states plan to rename I-540/U.S. 71 as I-493 long before construction begins across west-central Arkansas, though AASHTO has denied the designation for the Missouri portion. [1] LouisianaState transportation officials are currently working on plans to extend Interstate 49 to the south and east, from Lafayette to New Orleans roughly following the path of the current U.S. 90, which is at present a four-lane divided highway between the two cities. However, from Morgan City to near Raceland, U.S. 90 is an interstate-standard freeway, bypassing Houma to the north. In the Lafayette area, the project is divided into two projects, the I-49 Connector and the rest of the interstate from the Lafayette Regional Airport to LA 88. The I-49 Connector has a record of decision and is currently in the process of formulating the Environmental Impact Study. It is planned to be a six-lane elevated freeway, passing to the right of the current Evangeline Thruway corridor, as to be closer to the Central Business District in Downtown Lafayette. The rest of the freeway from the airport to LA 88 will be an at grade six-lane freeway with a two mile (3 km) segment of eight-lane elevated freeway through the suburb of Broussard. In the immediate New Orleans area, I-49 is planned to follow the route of the U.S. 90 Business (also known locally as the Westbank Expressway) through Westwego, Gretna and across the Crescent City Connection into downtown New Orleans, ending at I-10. "Future I-49" signage is visible along U.S. 90 and U.S. 90 Business, although as of 2007, construction has yet to begin. In addition to the southeastward extension, Louisiana officials are also working on clearing and grubbing and drainage for the new extension from Shreveport to the Arkansas line. The construction roughly parallels U.S. 71 northward from I-220. In Shreveport, I-49 is also proposed to be rerouted along Louisiana 3132/Inner Loop Expressway and concurrent with I-220 from I-20 to its proposed alignment near U.S. 71.[2] The stretch of the current I-49 between the Inner Loop and I-20 is likely to become an interstate spur. ArkansasIn southern Arkansas State Highway 549 has been built between Texarkana and Doddridge, 5 miles (8.0 km) from the state line. It is presently being constructed to complete the routing to the state line. Construction has not begun in west-central Arkansas. It is planned to follow the general route of U.S. 71 through the state between Interstate 30 and Interstate 40. North of I-40, a map shows the two disconnected pieces of the Interstate. South of the interruption it is labeled I-540. The bypass being planned will go around Bella Vista. Many motorists in Arkansas and Missouri, especially truckers, are desperate to see the highway fully connected and flowing due to current traffic congestion. This section, however, has been indefinitely postponed following a study showing that a toll would not be enough to pay for the highway. MoDOT has said construction on their part of the Bella Vista Bypass would be on hold until Arkansas begins construction of its part. MissouriIn Missouri, all of U.S. 71 from Anderson to Joplin has already been upgraded to interstate standards. A short bypass of Joplin, Missouri Route 249 has also been built as an eastern city bypass and is a possible extension of I-49 north. The bypass south of Anderson, MO is being upgraded to interstate standards. Heading north, many sections of divided highway still have at-grade intersections between Joplin and Harrisonville, yet are easily upgradeable. From Harrisonville to the south end of Kansas City at The Grandview Triangle - where U.S. 71 and Interstates 435 and 470 converge - the road is already built to interstate standards. In central and southern Kansas City, much of U.S. 71, has been realigned to Bruce R. Watkins Drive, which connects the Interstate 70/Interstate 670 interchange in downtown Kansas City with south Kansas City with Interstate 435 and Interstate 470. Many neighborhood associations in Kansas City have objected to the upgrading U.S. 71 to freeway. Three at-grade intersections - Gregory Boulevard (71st Street), 59th Street and 55th Street - prevent the I-49 designation north of The Grandview Triangle along U.S. 71. Modot has gone on record stating a court order keeps them from removing the stop lights, making conversion of this stretch unlikely. Exit list
