The street traces back to 1788 when it was first laid out, but its prominence traces back to its transformation that began in the 1960s.[3] In the 1890s, Poydras Street and Canal Street were early hosts of municipal lighting when gigantic spotlights in steel light towers were erected upon them by Muller Co.[4] In 1927, when its width measured 74 feet (22.6 m), the movement to widen it was begun by consultants for the City Planning Commission.[3] The street hosted the Poydras Market from 1838 to 1932.[3] As urban planning evolved, Poydras became the logical 4-lane connection between Expressways. It took until 1964 for a bond issue to pass that would acquire the properties to widen the street as had been recommended in 1927.[3] From November 23, 1964 until August 16, 1966, demolition, drainage installation, utility connection, paving, sidewalk construction and landscaping occurred, resulting in a six-lane 132-foot (40.2 m) wide street.[3] Many factors combined to give Poydras Street its prominent place in urban transit, including the erection of the Louisiana Superdome at one end and the Rivergate Exhibition Hall at the Mississippi River end in the late 1960s and the construction of One Shell Square in 1972.[3] Subsequently, more than a dozen skyscrapers were erected along the street that has become a central area circulator for vehicular traffic and host of modern high-rise construction.[3]
The northern side of Poydras Street between Baronne (Le Pavillon Hotel is at 833 Poydras Street on the corner of Baronne) and Carondelet Streets and between Camp and Tchoupitoulas Streets serves as the boundary of the original the district.[9]
The southern side of Poydras Street between Constance Street and Convention Center Boulevard serves as the boundary of the original portion of the district that subsumed the previously certified Warehouse District.[10]
The following addresses on Poydras Street were added as contributing properties for the first boundary increase: 820 Poydras, 900 Poydras, 902 Poydras, 906–08 Poydras and 918–20 Poydras.[11]
