Fully recognizing the need for a comprehensive study of an integrated expressway and arterial highway system for the Tampa Metropolitan area, the State Road Department of Florida, jointly with the County of Hillsborough and the City of Tampa, engaged Wilbur Smith and Associates to develop a Master Highway Transportation Plan for the Tampa Area. The geographic limits of the study area are defined as the city limits of Tampa on the north, Tampa Bay on the west, Hillsborough Bay on the south, and U. S. Route 301 on the east. The development of basic planning data and necessary field studies were initiated in November of 1956. The report, as contained herein, is an objective, factual study of traffic needs, roadway facilities and terminal parking necessary to meet these needs. The arterial street system necessary to supplement and complement the interstate highways traversing the area is recommended, together with detailed functional plans for the proposed expressway system. All traffic needs were evaluated in terms of projected 1975 traffic requirements.
