The 125-acre (0.51 km2) shopping district is located south of Airport Road on the east side of Interstate 95, two miles (3 km) east of Jacksonville International Airport (JIA).

The T2 Laboratories explosion and fire occurred on December 19, 2007, in Jacksonville, Florida, resulting in the deaths of four people and the injury of fourteen others. T2 Laboratories Inc. was a facility that specialized in the design and manufacture of specialty chemicals primarily for gasoline additives.The explosion's force was equivalent to detonating 1,400 lb (640 kg) of TNT and it spread debris up to 1 mi (1.6 km) from the plant. Following the explosion, every HAZMAT unit in Jacksonville and over 100 firefighters fought the ensuing blaze, which a spokesman termed a "hellish inferno". The blast killed Robert Scott Gallagher, 49; Charles Budds Bolchoz, 48; Karey Renard Henry, 35; and Parrish Lamar Ashley, 36. At the time of his death, Gallagher was Marketing Director for T2 Labs. Fourteen people were hospitalized for chemical exposure or their injuries after the blast. The company laid off its workers and shut down in the following months.In September 2009, a report was released by the U.S. Chemical Safety and Hazard Investigation Board as to the cause of the accident. The explosion occurred in a 2,500 US gal (9,500 L) batch reactor during production of methylcyclopentadienyl manganese tricarbonyl (MCMT). The reactor cooling system, which lacked backups, failed; this led to a thermal runaway. Pressures rapidly reached 400 psi (28 bar), bursting the rupture disc, but the relief was insufficient to prevent the continued runaway reaction. Nearby witnesses described a jet engine-like sound as high pressure gases vented from the reactor. At the same time pressure increased in the reactor, temperatures also increased in the reactor until the solvent (diglyme) reached its decomposition temperature. The pressure and temperature continued to increase until the reactor violently ruptured and the MCMT exploded, destroying the reactor. Damage from the explosion was severe enough that 4 buildings in the immediate vicinity of the plant were condemned.

The Northside is a large region of Jacksonville, Florida, and is generally understood as a counterpart to the city's other large regions, the Urban Core, Arlington, Southside, Westside, and the Beaches. The expansive area consists of historic communities, cultural landmarks, protected ecosystems and vital transportation and logistics facilities, all fundamental to the history and development of Jacksonville. The Northside was incorporated into the city in 1968 as a result the Jacksonville Consolidation, a city-county consolidation of the governments of the City of Jacksonville and Duval County. The area houses a sizable share of the city's transportation and logistics infrastructure, including Jacksonville International Airport, Jacksonville station, JAXPORT Cruise Terminal, Blount Island Marine Terminal and Dames Point Marine Terminal. The area is also home to the Jacksonville Zoo and Gardens, which relocated to the Northside in 1925 and has since doubled in size. There is no consistent definition for what constitute the boundaries of the Northside, but studies have revealed the vernacular region to be considered roughly north of the Urban Core and Westside at 20th Street, and west and north of the St. Johns River.

After a four-month hiatus in service, Carnival restarted Jacksonville-Bahamas cruise service aboard the Carnival Fascination, which provided service from Jacksonville until April 2016, being replaced with Carnival Elation. The Carnival Elation was replaced by the Carnival Ectasy in 2019. As of 2022, cruises from Jacksonville visit the Bahamas and Eastern Caribbean sailed aboard the Carnival Elation.During the COVID-19 pandemic all cruises were suspended. The first cruise post-pandemic was the American Queen Voyages ship, Ocean Voyager which departed February 21, 2022 for a 12-day cruise to destinations along the Atlantic coast. The Carnival Spirit operated from Jacksonville from March 7, 2022 to April 9th, 2022.Five cruise ships were chartered to serve as floating hotels during the week preceding Super Bowl XXXIX in February 2005. Four of the vessels docked at JAXPORT terminals, providing over 3,500 rooms plus restaurants and night clubs for fans.The Jacksonville Port Authority had plans to relocate the cruise terminal. In 2008, an 8-acre (32,000 m2) parcel was purchased in the small fishing village of Mayport as the site of a permanent $60 million facility. The economic crisis delayed the project, and opposition from local residents was vehement; a lawsuit seeking an injunction was filed. In March 2010, the authority announced that they were starting over and reviewing all possible locations for the cruise terminal.
