The Maestri Bridge crosses Lake Pontchartrain north from Pointe aux Herbes and Irish Bayou, joining New Orleans with the North Shore at Eden Isle and Slidell. Photos taken October 12, 2016.

U.S. 11 travels from Powers Junction in New Orleans to Slidell, Pearl River and Nicholson, Mississippi. The two-lane route parallels Interstate 10 north along the Maestri (Five Mile) Bridge across Lake Pontchartrain from Irish Bayou, and parallels or overlaps with Interstate 59 northward from Pearl River to Mississippi.

Until 1937, U.S. 11 concluded at the settlement of Santa Rosa in Hancock County, Mississippi, where then-U.S. 90 turned from Pearl River, Louisiana toward Bay St. Louis. The 1936 official Mississippi Highway map shows U.S. 11 and 90 combining southwest from Santa Rosa to Slidell and New Orleans, using what is now LA 433 between Slidell and the Rigolets, and U.S. 90 from the Rigolets westward into central New Orleans.

U.S. 90 shifted southward from its northern arc through Santa Rosa in 1937 onto the present day alignment from Pearlington, Mississippi westward to New Orleans. U.S. 11 remained along the Santa Rosa to Slidell alignment and LA 433 until June 28, 1939, when the route was realigned onto the Watson-Williams Bridge across Lake Pontchartrain.1 This resulted in a truncation of the U.S. 11/90 overlap west of Powers Junction.

Construction of Interstate 59 in the late 1950s led to the relocation of U.S. 11 from Santa Rosa, Mississippi west to Pearl River onto the freeway after 1960. The former alignment was subsequently abandoned and repurposed as a local access road for Pearl River Wildlife Management Area. The old U.S. 11 bridge over Pearl River was demolished by the mid-1970s.2
