Interstate 310 Mississippi

 

The projected path of Mississippi 601 takes the Central Harrison Connector south from near the Interstate 10 interchange with Canal Road to 30th Avenue in Gulfport. The project will likely include a temporary access road linking the freeway with Canal Road until funding is made available for the massive interchange with MS-601 north and I-10.

Proposed Routing

Interstate 310, also known as Mississippi 601, is the Canal Road - Port 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.

Land clearing was completed along a swath of right of way reserved for the Central Harrison Connector in 2011. This view looks south from South Boulevard near Gulfport Dragway at the future path of Mississippi 601. Photo taken April 5, 2012.

Route Status / Central Harrison Connector

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 was scheduled to begin in 2008,2 but remains on hold as of May 2009. 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. See Central Harrison County Connector Highway Project History from MDOT for more detail.

East Harrison Connector

An adjacent freeway proposal that is under consideration involves a new road, the East Harrison Connector, from Interstate 10 at the Exit 41 interchange with former Mississippi 67 at Woolmarket southward into Biloxi. Plans for that route entail a four to six lane roadawy over Popp's Ferry Road en route to a high-level bridge across the Back Bay of Biloxi1. The highway proposal ends at U.S. 90 west of Veteerans Avenue. See the Connection Report from MDOT for additional details.

The southern terminus planned brings Interstate 310 to a close at U.S. 90 and the Port of Gulfport west of U.S. 49 near downtown Gulfport.
