Bayou Bonfouca, which empties into Lake Pontchartrain 3 miles NW of the Southern Railway causeway N swing bridge, is the approach to the town of Slidell. A dredged channel leads for about 6 miles from deep water in Lake Pontchartrain to Slidell. In 1994, the controlling depth was 6 feet across the bar, thence 7 feet to the State Route 433 highway bridge at Slidell. The channel across the bar is marked by lights, buoys, and daybeacons. The bridge at Slidell has a swing span with a clearance of 6 feet.
The bridgetender monitors VHF-FM channel 13; call sign KMC-226. The bridgetender lives near the bridge and will open on signal, but there may be a slight delay. The overhead power cable at the bridge has a clearance of 58 feet. In 1982, the cable was reported to have been removed. An overhead power cable about 0.4 mile above the bridge has a clearance of 59 feet.
