This Bridge is part of the "Old Spanish Trail," from Palm Beach,
Florida, to Los Angeles, Cal. Route U.S. No. 90.
Published by C.B. Mason of New Orleans, Louisiana.
When it was completed, the bridge was the "World's Largest Continuous
Concrete Highway Bridge"
Another view of the bridge:
1930's era poscard reads on back, "The new $5,500,000 Pontchartrain Bridge spans Lake Pontchartrain from Pointe Aux Herbes,
south of New Orleans to Slidell on the north shore. The bridge, with its approaches, is the longest of its kind in the country.
The actual span, entirely of concrete, is more than 5 miles in length and offers a chance for a beautiful, cool drive over
the waters of Lake Pontchartrain. It brings New Orleans subsequently closer to the North and East."
