on November 22, 1963, and the section between Orlando and the northern terminus of I-75 opened on July 24, 1964, completing the mainline. I-95 realignment The Bureau of Public Roads approved an Interstate 95 alignment that used of the Turnpike from PGA Boulevard (SR 786) in Palm Beach Gardens north to SR 70 in Ft. Pierce in the 1950s. In the mid-1960s, the State Road Department authorized traffic counts be conducted to determine if the separation of Interstate 95 from the Turnpike was feasible, with arguments that using a concurrent alignment was costing Florida money for federal highway funding, but not without the concern of losing toll revenue. Over time, the interstate adopted a route closer to U.S. Route 1, including parallel between Stuart and Palm Beach Gardens, with the turnpike being removed from the I-95 alignment in 1973, and I-95 being completed in 1987. Reckless spending With the St. Petersburg Times in 1963, a team led by Martin Waldron wrote a total of 150,000 words as part of the newspaper's coverage of unchecked spending by the Florida Turnpike Authority that led to estimated costs quadrupling from initial estimates of $100 million. Waldron received a tip about excessive spending by John Hammer, chairman of the Florida Turnpike Authority, which included expensive hotels and meals, corsages for his secretary and overcharging for a chartered plane. His coverage earned the newspaper the Pulitzer Prize for Public Service in 1964, the first for the newspaper, and led to changes in the way the state of Florida managed highway construction projects. System expansion With Florida still growing in population in the 1960s, preliminary studies began for expanding portions of the Turnpike to six lanes in South Florida and additional north–south highways in that area. Dade County and the State Road Department developed a plan for the West Dade Expressway (now known as the Homestead Extension of Florida's Turnpike), beginning at the Turnpike near the Dade County/Broward County line, turning westward and southward, and terminating at Florida City in southern Dade County. In 1967, the Florida State Turnpike Authority was authorized to perform engineering and feasibility studies on the West Dade Expressway and the Bee Line Connector extension, now known as the Martin Andersen Beachline Expressway. The results of the studies came in December 1968, but due to an uncertain bond market and an unknown future for the toll authority, decisions on the roads were
