History

LA 3046 began as part of the Greater New Orleans Expressway, a 1950s project to transform the century-old Harlem Avenue right-of-way into a multilane highway connecting U.S. 90 (Jefferson Highway), U.S. 61 (Airline Highway, now Drive), and

(now Boulevard) to the Lake Pontchartrain Causeway then under construction. Harlem Avenue would be renamed Causeway Boulevard. The expressway's name survives in the Greater New Orleans Expressway Commission which maintains and patrols the Causeway bridge. The multilevel rotary interchange at U.S. 61 (Airline Highway) and the hook ramp at U.S. 90 (Jefferson Highway) were opened in June 1957. The narrow hook ramp originally carried two-way traffic (southbound Causeway Boulevard to eastbound Jefferson Highway and eastbound Jefferson Highway to northbound Causeway Boulevard). It was reconfigured in 1999 to carry one-way traffic, with southbound Causeway Boulevard traffic now crossing the Jefferson Highway median to turn eastbound. The ramp's clearance over Jefferson Highway was increased from to in 2009 to facilitate truck traffic passing underneath. Acceleration and deceleration lanes were added to the north side of the rotary interchange in 2003, while the south side remains in its original configuration.
