Slidell, Louisiana’s foundations were laid in 1882 when the New Orleans and Northeastern [NONE] Railroad surveyors mapped out a new route eastward from New Orleans. The new route would connect New Orleans directly to Meridian, Mississippi, and destinations in the eastern United States. Surveyors made their way through the wetlands of New Orleans East, then crossed five-miles of water on Lake Pontchartrain, and then more wetlands on the north shore until reaching what would soon become the town “Slidell.” The NONE Railroad Company established an industrial 70-acre construction site near Bayou Bonfouca and began work on the new line. The railroad bridge that they built was the first bridge to cross Lake Pontchartrain. It was the long RR Bridge in the world when built. It was considered and engineering marvel at the time. Soon, the population in the area had grown sufficiently for the Louisiana State Legislature to grant a charter to the growing community, and Slidell officially became a town on November 13, 1888.
Sometime prior to Slidell’s formal incorporation in 1888, its first streets had already been laid out in a grid pattern, mostly east of the railroad, running three blocks along the railroad by four blocks deep. Bonfouca Street, now Bayou Lane, lay in the short stretch between the railroad and the bayou. East of the tracks, the north-south streets were Bayou (now Front), First, Second, Third, and Fourth. The east-west streets were Fremaux, Erlanger, Bouscaren, and Cousin.
Erlanger, slightly wider than the others and designated as an avenue, was named for Baron Frederick Erlanger, head of the banking syndicate which financed the railway. Baron Erlanger named the town for his deceased father-in-law, John Slidell, who had been a prominent state, national and confederate political figure. Col. Leon J. Fremaux, a prominent Louisiana engineer and planner, drew the original plans for Slidell and Fremaux Avenue now bears his name. Bouscaren Street was named for G. Bouscaren, the chief engineering officer of the railroad, and Cousin [‘Coo-zan’] Street took its name from a locally prominent family.

After its founding, Slidell was home to one of the largest creosote plants in the world, one of the country’s largest brick manufacturing facilities, several large lumber mills, and a shipyard. The shipyards in Slidell contributed significantly to the national war effort in both World Wars. Many Slidell residents worked in New Orleans ship, tank, and airplane construction during World War II.
In the 1960s, Slidell began to assume its modern profile as the middle of three local sites in NASA’s lunar landing program: Michoud assembly facility in New Orleans East, a large computer facility in Slidell, and the Mississippi test facility in Hancock County, Mississippi; now the Stennis Space Center.
Slidell is located at the southeastern tip of St. Tammany Parish in Louisiana’s famous Ozone Belt. It is about three miles from the north shore of Lake Pontchartrain and is surrounded by rivers and bayous. The largest municipality in the parish, Slidell has grown from a population of 364 in 1890 to 24,142 in 1990; Slidell’s 1999 population was estimated to be 32,000. Today, Slidell continues to deal with urban planning and growth, while preserving a sense of present and past. Slidell is a dynamic community accommodating an ever-increasing number of residents and businesses seeking quality living and expanding opportunity.
