This enormous bridge is a cantilever truss bridge, and while not a very early example of this bridge type, it is nevertheless highly noteworthy due to the length of its main span. Almost all the connections on this bridge are riveted, but eyebars and pin connections can be found near the towers of the bridge.

Due to the elevated nature of the approaching roadway for this bridge, defining the start and end of this bridge may vary depending on the source consulted. HistoricBridges.org is listing the total length of the bridge as found in Wikipedia.

The current name of the bridge was chosen as the result of a contest following the completion of the second bridge (which created a one-way couplet of bridges here) in 1988. The name Crescent City Connection Bridge applies to both bridges. The name Greater New Orleans Bridge applied to the original bridge when it was built. New Orleans notable Vietnamese population also knows the bridge as Cầu Con Cò (Pelican Bridge) due to blue signs on the portal bracing of the bridge that feature a pelican from the state flag.

When this bridge was designed, the famous firm Modjeski and Masters was apparently using the name "Masters and Henderlite" per study documents prepared during the design of the bridge.

While not historic, the companion westbound truss bridge bears mention as well. It was built from 1983-1988, with the main spans completed in 1985. Like the original historic (today eastbound) bridge, the westbound bridge was designed by Modjeski and Masters, and the bridge displays similar span lengths and overall bridge design. However as a newer bridge, 1980s thinking into member design is found in the lack of rivets, no v-lacing or lattice, etc. One unusual feature (for a 1980s bridge) is the use of eyebars near the cantilever towers on the top chord. Eyebars were used on the original bridge as well, but eyebars were not commonly used in bridges in the 1980s. The 1988 bridge was constructed by the Harris Structural Steel Company of South Plainfield, New Jersey.
