Construction
of the $50,000,000. Bridge began in February 1967. It opened on August
3, 1969. Its distinctive towers
and graceful curve brought it the "Most Beautiful Bridge"
Award of Merit from the American Institute of Steel Construction
in 1970.
The 2.12-mile (11,179-foot) long bridge connects with Interstate 5 in
San Diego and becomes Route 75 in Coronado.
With a vertical clearance of approximately 200 feet, the tallest ships
can pass beneath it.
Beginning at the toll plaza in Coronado, the bridge ascends at a 4.67%
grade, curving 80 degrees toward San Diego. Clusters of submerged piles
support the 30 mission-arch shaped concrete piers. The 54-inch diameter
piles were driven and jetted to depths of 100 feet in the Bay's bottom.
