I finally made the walk! Built in 1954-1957 for a cost of $100,000,000.00
Big State and local police presence. Officers all along the bridge, officers on bikes, motorcycles, and horses patrolling, and a helicopter overhead. About every 5th officer had a long gun case on his back, which I assume contained an assault rifle? Boats were also patrolling in the water below.
Dump trucks blocking the entrance.
To walk across was free, but the Ferry ride back cost $20
