“What if this canal could talk?” it might tell a story about ambition, engineering marvels, and nature’s raw power. Today we are standing near the Seabrook Bridge. The bridge overlooks the Inner Harbor Navigation Canal. Locally it is often called the Industrial Canal.
The Inner Harbor Navigation Canal is a 5.5-mile waterway in New Orleans. It connects the Mississippi River to Lake Pontchartrain. The vision for this canal dates back to Spanish colonial times. They dreamed of connecting the river to the lake for shipping.
Construction finally began in 1918. The project cost 19 million dollars. In 1923, the Inner Harbor Navigation Canal opened. It allowed large cargo ships and barges to access river wharves. The canal is 30 feet deep at its lake end. It is about 150 feet wide at its lock end.
The Inner Harbor Navigation Canal provides about 11 additional miles of waterfront to the Port of New Orleans. This canal spurred industrial development in the 1930s. Wharves and dry docks sprang up. Many people settled in the Lower Ninth Ward due to these job opportunities.
Eight bridges span the Inner Harbor Navigation Canal. At the north end of the canal is the Seabrook Bridge. It is officially named the Senator Ted Hickey Bridge. The Seabrook Railroad Bridge is next to it.
This area suffered greatly during Hurricane Katrina in 2005. Storm surge caused multiple breaches in the canal’s floodwalls. A large barge floated through one breach. It ended up in the Lower 9th Ward.
Since Katrina, efforts have focused on improving storm defenses. One project is the IHNC Seabrook Floodgate Structure. Another is the IHNC Lake Borgne Surge Barrier.
The Industrial Canal Lock connects the canal to the Mississippi River. It is shorter and narrower than modern locks. The U.S. Army Corps of Engineers is working to replace it with larger locks.
The Inner Harbor Navigation Canal has a complex history. It involves dreams of progress and devastating reminders of nature’s power. It stands as a testament to New Orleans’ resilience.
