Abstract:
The Second Lake Pontchartrain Bridge, a trestle-type strucrures 24-miles long, consists of precast prestressed concrete deck units, precast concrete pile caps, and precast prestressed cylinder piles. . .This paper presents a study of the two bridges to indicate the improvements in the art and science of prestressed concrete design; the progress in concrete technology; the advance in mass production techniques for fabrication and construction of bridge piers and spans composed of multiple identical units; changes in construction procedures; and the advances in traffic safety during these intervening twelve years.
