Interstate 310 Mississippi

Future Aspirations

Interstate 310, also known as Mississippi 601, is the Canal Road Connector in Gulfport.4 It is proposed to begin at a new interchange with Interstate 10 that will also serve as the southern terminus of the proposed U.S. 49 Gulfport to Hattiesburg freeway (also known as Mississippi 601 North). From there, Interstate 310 is planned to travel south to the port of Gulfport, where it would end.

The highway was originally considered for designation as Interstate 210, but is now planned as Interstate 310 since the freeway will spur from Interstate 10 to the Port of Gulfport.2 The road is not planned to reconnect back to Interstate 10.

Status

Planning and design is underway involving a new six-mile freeway linking Interstate 10 to the port of Gulfport. Assuming funding is made available, Interstate 310 would be built within four or five years after design is completed, putting completion around 2012.3, 4 Tentatively touted as Interstate 310, the $300 million project is already underway. Design began in 2005, and right of way acquisition began 2006.4 Construction is scheduled to begin in 2008.2 If approved, the federal government would cover 90% of the maintenance costs of the new freeway. The freeway would otherwise be added to the state highway network with Mississippi Department of Transportation (MDOT) footing the entire bill.1

The design of Interstate 310 preferred by the Mississippi Department of Transportation (MDOT) provides for an elevated viaduct freeway. This drew immediate criticism from Gulfport Mayor Brent Warr, who prefers an at-grade alignment for the freeway.2 The concern is that the areas below the elevated freeway will deteriorate in the same manner as the neighborhoods below elevated Interstate 110 in Biloxi. The discussion on how the freeway will be constructed is still underway.

Another freeway proposal that is under consideration would be a separate freeway that would originate from Interstate 10 at the Exit 41 interchange with Mississippi 67 at Woolmarket. From there the freeway will expand from four to six lanes as it crosses Popp's Ferry Road en route to a high-level bridge across the Back Bay of Biloxi. The highway would turn parallel to Hiller Park once in the city of Biloxi.1
