Interstate 110 (Mississippi) is a short spur route serving Gulfport and the Gulf of Mexico shoreline, connecting downtown Gulfport to Interstate 10 near Biloxi and D'Iberville. The route functions as an urban connector for vehicular traffic between coastal destinations such as Gulfport-Biloxi International Airport and attractions including Gulf Islands National Seashore and the Port of Gulfport. It supports regional access to cultural venues like the Mississippi Coast Coliseum and Convention Center, recreational sites such as Buccaneer State Park, and federal facilities including the Naval Construction Battalion Center Port Hueneme-related Reserve components.

Route description

Interstate 110 begins at a terminus in downtown Gulfport near the Gulfport Harbor waterfront and proceeds north as a controlled-access freeway linking urban corridors such as U.S. 90 and MS 605. The freeway crosses industrial zones associated with the Port of Gulfport and passes near landmarks like the Gulfport Premium Outlets area, the Island View Casino Resort, and civic sites including Gulfport Central High School and the Gulfport Municipal Auditorium. Moving northward, I‑110 intersects local arterials that provide access to neighborhoods adjoining Biloxi and commercial districts near D'Iberville before meeting I‑10 at a full interchange offering movements toward Mobile, New Orleans, and Jackson. The corridor runs adjacent to wetlands mapped in regional planning by the Mississippi Department of Transportation and lies within the coastal plain landscapes documented by the United States Geological Survey.

History

Planning for a coastal spur to link the Gulfport waterfront with the transcontinental Interstate Highway System traces to postwar infrastructure initiatives influenced by federal programs such as the Federal-Aid Highway Act of 1956 and state-level projects administered by the Mississippi Department of Transportation. Early alignment studies referenced interstate connectors constructed in other ports, like the I‑510 and spurs serving New Orleans and Mobile. Funding rounds that included allocations from agencies similar to the USDOT and coordination with the Harrison County Board of Supervisors culminated in the designation of the spur as part of the Interstate Highway System in the late 20th century. Construction phases paralleled regional growth tied to enterprises such as the MSPA and casino developments like Beau Rivage Resort & Casino and Beauvoir-area tourism. The corridor experienced storm impacts from events including Hurricane Katrina; post-storm reconstruction incorporated resilience measures advocated by the Federal Emergency Management Agency and design criteria from the American Association of State Highway and Transportation Officials.

Exit list

The interchange sequence begins at the southern terminus in Gulfport and proceeds north to I‑10 near D'Iberville, with connections to U.S. 90, local connectors to MS 605, and ramps serving commercial nodes near the Gulfport-Biloxi International Airport. Key interchanges provide access to downtown districts proximate to Gulfport Harbor, cultural institutions like the Mississippi Coast Coliseum and Convention Center, and leisure destinations such as the Island View Casino Resort and Hard Rock Hotel and Casino Biloxi. The I‑10 junction allows movements toward Pearl River corridors and interstate travel to metropolitan centers including New Orleans and Mobile. Auxiliary ramps and collector–distributor lanes manage traffic flows to industrial access points tied to the Port of Gulfport and logistics operators that serve inland markets such as Hattiesburg and Jackson.

Traffic and tolls

Traffic volumes on the spur reflect commuter, tourist, and freight demand linking coastal attractions like the Gulf Islands National Seashore and gaming resorts including Beau Rivage Resort & Casino with interstate freight movements toward inland hubs such as Hattiesburg and Jackson. Peak-season loads coincide with events at the Mississippi Coast Coliseum and Convention Center and holiday travel to destinations like Gulfport Beach. The corridor is monitored by the Mississippi Department of Transportation for vehicle miles traveled and level-of-service metrics used in federal reporting to the Federal Highway Administration. There are currently no tolls on the spur; past regional toll discussions mirrored proposals elsewhere in the Gulf Coast region such as those debated for bridges near Biloxi Bay and financing plans pursued by the Mississippi Development Authority.

Future plans and improvements

Planned improvements emphasize resilience, capacity, and multimodal access in coordination with agencies including the Mississippi Department of Transportation, the Federal Highway Administration, and local governments like the City of Gulfport. Projects under study include interchange upgrades to improve traffic flow toward I‑10, pavement rehabilitation consistent with standards from the American Association of State Highway and Transportation Officials, and storm-hardening measures informed by lessons from Hurricane Katrina and Hurricane Zeta. Regional planning efforts by entities such as the Gulf Regional Planning Commission and the Harrison County Development Commission examine transit linkages to the Gulfport-Biloxi International Airport and freight improvements supporting the Mississippi State Port Authority. Environmental reviews reference habitats cataloged by the United States Fish and Wildlife Service and wetlands mapping by the United States Army Corps of Engineers as part of future permitting and mitigation strategies.
