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 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 the current LA 433 between Slidell and the Rigolets, and current 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 current alignment from Pearlington, Mississippi westward to New Orleans. U.S. 11 continued on the Santa Rosa to Slidell alignment and along present-day LA 433 until June 28, 1939, when the route was realigned onto the Watson-Williams Bridge across Lake Pontchartrain.1 This led to 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 new freeway after 1960. The former alignment was subsequently abandoned and now acts as a local access road for Pearl River Wildlife Management Area. The bridge over Pearl River was demolished by the mid-1970s.2

Continuing toward Slidell along U.S. 11 north. Also known as the Maestri Bridge, the two-lane concrete bridge opened to traffic on February 18, 1928 as a toll bridge. Tolls were charged until 1938, when the state purchased the span and redesignated it as part of a relocated U.S. 11.3 Photo taken 12/10/07.

U.S. 190 Business west concludes at U.S. 11 (Front Street) via Fremaux Avenue. Photo taken 12/10/07.
Like the U.S. 51 business route in Hammond, U.S. 190 Business only connects with its parent on one end. U.S. 11 north provides the return route to U.S. 190 (Gause Boulevard) while U.S. 190 Business east follows Fremaux Avenue to Interstate 10 and Shortcut Highway. Photo taken 12/10/07.
Continuing through downtown Slidell along U.S. 11 (Front Street) north. Photo taken 12/10/07.
An overhead sign assembly precedes the U.S. 11 (Front Street) intersection with U.S. 190 (Gause Boulevard). U.S. 190 travels west to Lacombe and Covington and east to end at U.S. 90 outside Slidell. U.S. 90 continues the drive to Bay St. Louis. Photo taken 12/10/07.
Interstate 10 and 12 trailblazers accompany the U.S. 11 and 190 shield assembly at the corner of Front Street and Gause Boulevard. U.S. 190 comprises the main commercial arterial through Slidell, offering a slow go to Interstate 10. U.S. 11 continues along side a NS Railroad line 1.6 miles to Interstate 12. Photo taken 11/06/99.
U.S. 11 south
Long since removed, an Interstate 12 Louisiana shield posted with the folded diamond interchange between U.S. 11 south and Interstate 12 directed traffic onto eastbound. A guide sign affixed to the I-12 overpass replaced the shield assembly in 2000. That too was replaced by 2012. Photo taken 11/06/99.
The control city of Bay St. Louis for Interstate 12 east is the next destination served by Interstate 10 east. I-10 bypasses the Hancock County city en route to Gulfport and Biloxi. Photo taken 04/20/12.
Drivers bound for Interstate 10 or Interstate 59 north loop away from U.S. 11 south. Modern mast-arm supported traffic lights in Louisiana now feature backplates with a reflective yellow outline. These are appearing all across the country from Indiana to Florida. Photo taken 04/20/12.
U.S. 11 south ends at Powers Junction and U.S. 90. U.S. 90 (Chef Menteur Highway) enters eastern New Orleans by way of the Rigolets and Fort Pike to the east. Photo taken 12/10/07.
U.S. 90 continues west from Powers Junction and U.S. 11 to New Orleans East. Until 1936 both U.S. 11 south & 90 west turned at Powers Junction toward central New Orleans. U.S. 90 shifted away from the overlap with U.S. 11 through Slidell in 1937, ultimately leading to a truncation of U.S. 11 east to Powers Junction. A set of flashers and a stop sign for U.S. 11 traffic governs the movements between the two US routes otherwise. Photo taken 12/10/07.
