Interstate 110 Mississippi
Interstate 110 is a short freeway spur linking Interstate 10 and Mississippi 15 & 67 at D’Iberville with U.S. 90 (Beach Boulevard) and Downtown Biloxi. The freeway incorporates one of the few drawbridges in the Interstate system as it traverses the Back Bay of Biloxi between Exits 1D and 2. South from the span, I-110 travels along a four lane viaduct, with the trumpet interchange at U.S. 90 protruding partially over the waters of the Gulf of Mexico.
A flyover remains planned to replace the loop ramp connecting Interstate 10 west with Interstate 110 south. Funding may delay the project until 2025.5
Interstate 110 fully opened to traffic between U.S. 90 and Interstate 10 in 1988.1

Interstate 110 spurred south to the Bayview Drive ramps just across the Back Bay of Biloxi in 1977. MS-15 remained posted from there south along Caillavet Street to U.S. 90 by Downtown.
Mississippi 15 formerly cosigned with Interstate 110 for its entire length until March 2009. Opening at that time of the Biloxi – D’Iberville Scenic Expressway included a new alignment of Mississippi 67 to the southeast and a new trumpet interchange with Mississippi 15. As a result, MS-15 was truncated to the new MS-67, with MS-67 ending at the cloverleaf interchange with Interstates 10 and 110. MS-15 previously ran along Caillavet Street and Central Avenue to the east of I-110 through Biloxi and D’Iberville.
Hurricane Katrina devastated the Biloxi and Gulfport area with its landfall on August 29, 2005. Long portions of U.S. 90 were virtually destroyed in the process, but Interstate 110 fared well and quickly reopened. Many of the signs within Biloxi for Interstate 110 were replaced, but otherwise the freeway remained unchanged.
Construction started in 2013 on Phase I of the Interstate 10/110 Interchange Improvements project in D’Iberville. The $29.7-million project included new interchanges along I-10 at D’Iberville Boulevard (since renamed to Galleria Parkway) and Lamey Bridge Road. It also realigned the loops joining Interstates 10 and 110 while adding a collector distributor roadway to I-10 east and auxiliary lanes. Phase II, costing $11.4-million, started in March 2014. This aspect added a half diamond interchange between Big Ridge Road (since renamed as an extension of Popps Ferry Road) and I-110.2
The new c/d roadway from Interstate 10 east to Interstate 110 opened on January 21, 2015.3 The Diverging Diamond Interchange (DDI) at Galleria Parkway opened to traffic following a ribbon cutting ceremony on June 2, 2015.4 The new ramps between I-110 and Popps Ferry Road opened on September 3, 2015, with a formal ribbon-cutting ceremony wrapping up all work on the two-phase project.5
A separate four-phase project focused on the replacement of the at-grade intersection of Mississippi 67 with Promenade Parkway / Sangani Boulevard just beyond the Interstate 110 north end. Work on the $7.3-million project started in March 2012. The congested at-grade intersection was replaced with a new 17 feet overpass and folded-diamond interchange. New ramps to MS-67 opened on July 25, 2013, while side work on Sangani Boulevard continued through November 2013.6
Most of the sign bridges along Interstate 110 on the Walter L. Nixon Memorial Bridge over the Back Bay of Biloxi and the elevated freeway through Biloxi were removed by November 2015. Overall 20 overhead signs were taken down by the Mississippi Department of Transportation (MDOT) as part of sign replacement project underway throughout southeast Mississippi. The project replaces sign bridges with cracked and substandard trusses with new assemblies adhering to current hurricane standards.7
