World's Longest Bridges

This 1935 POST CARD OF 'PONTCHARTRAIN BRIDGE, NEW ORLEANS, LA.' Back reads '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 IT?S APPROACHES, IS THE LONGEST OF IT?S 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.'

Another view of  the '5 mile bridge' to Slidell which includes a map of the route.
This postcard was published by Alphonse Goldsmith, New Orleans, LA.
