2002 Traffic Study

1.1 Background
The Florida Department of Transportation (FDOT), the Hillsborough County Metropolitan Planning Organization (MPO), and the Pinellas County MPO have identified the need to make improvements to Gandy Boulevard in both Pinellas and Hillsborough Counties. Portions of the project lie within the city limits of St. Petersburg and Tampa. The need for capacity improvements in these segments of Gandy Boulevard are included in the Pinellas County MPO’s 2020 Long Range Transportation Plan (LRTP) (adopted December 9, 1998) as a Policy Plan Roadway Improvement, and the Hillsborough County MPO’s LRTP (adopted November 9, 1998). Results of the previous Project Development & Environment (PD&E) Studies and the Major Investment Study (MIS) (dated March 2001) for the Gandy Corridor will be utilized in this study. This study was originally published in January 2002. The current report reflects changes in ramp configurations being considered at the interchange of Gandy Boulevard and the Lee Roy Selmon (Selmon) Expressway, an optional partial directional interchange at Westshore Boulevard, an assessment of project staging and FDOT’s comments received in March 2002.

1.3 Objective
The objective of this Traffic Technical Memorandum is to document existing conditions, crash analysis, the methodology and procedures used in the development of the future traffic estimates, and traffic operations for different improvement alternatives along the Gandy corridor. In addition, the traffic data necessary for noise and air studies for existing year (2000), opening year (2010) and design year (2025) alternatives are documented. The traffic analysis for viable alternatives was based on a minimum acceptable Level of Service “D” in accordance with the LRTP policies in Hillsborough and Pinellas Counties and the FIHS urban criteria. English units were used in preparing this memorandum.

2007 Gandy Area Transportation Study

Gandy Area Transportation Study
Executive Summary

The portion of the Interbay peninsula south of Gandy Boulevard has recently experienced a renaissance of infill and redevelopment that has caused citizen concern relative to traffic congestion. The City of Tampa initiated a transportation planning study to assess transportation needs associated with approved, but not yet built, developments and to assess the potential for further intensification. This study assesses the magnitude of growth in the study area, develops a solution to meet estimated short-term needs, and identifies issues and strategies to deal with continued, longer-term development.

Most of the concerns are focused on Westshore Boulevard, on the western edge of the study area. Roads serving this area are currently full, with no excess capacity to accommodate additional traffic. The City of Tampa and the Florida DOT have scheduled improvements in the area, but they are inadequate to accommodate the planned traffic growth. Additional roadway improvements with an estimated cost of $20 to $40 million have been identified to replenish the capacity of the road network, almost offsetting expected traffic growth. These improvements include:

  • Connecting Tyson Avenue from Westshore Boulevard to Manhattan Avenue
  • Four-laning Westshore Boulevard from Tyson Avenue to Fair Oaks Avenue
  • Adding a southbound lane on Manhattan Avenue from Gandy Boulevard to Tyson Avenue
  • Other relatively low-cost intersection and bicycle and pedestrian safety improvements.

Alternative methods to fund these improvements were explored, and developer assessments appeared to be the most promising strategy. Additional improvements to roads in the Interbay Peninsula further north were also identified to address the need for additional capacity.

To allow additional growth in the area, be it from already-entitled lands or proposals to intensify development beyond the allowances of current zoning, the City must agree upon the need for more substantial and costly improvements (if currently adopted transportation service goals are to be met), reduced quality of service standards, or limitations on the location and intensity of future growth.

The City will be updating its Comprehensive Plan in 2007, and a positive outcome of this study will be to apply lessons learned from this study to amendments to the plan. To be an effective Plan, the City needs to more clearly define the character, intensity, and location of desired urban development, and its supporting transportation system. Funding sources to allow implementation of the Plan must be identified and the role of development and residents of the City in implementing and funding the Plan should be defined. Finally, the City must remain committed to implementing the vision it establishes.

For Selmon West Extension Project Development and Environment (PD&E) Re-Evaluation Study
From the Gandy Bridge to the western terminus of the Selmon Expressway in Hillsborough County

Executive Summary

This document was prepared as part of the PD&E re-evaluation study for Gandy Boulevard (SR 600) from west of Westshore Boulevard to east of Dale Mabry Highway in Hillsborough County. The Gandy Boulevard corridor is primarily an east/west facility, which in its entirety, extends from a western terminus at Gulf Boulevard in Pinellas County to an eastern terminus at Bayshore Boulevard in Hillsborough County. The study corridor project location map is shown in Figure ES-1. The Gandy Boulevard corridor is functionally classified as an Urban Other Principal Arterial highway and is part of the Florida Strategic Intermodal System (SIS), which is a statewide network of high priority transportation facilities, including the State’s largest and most significant airports, spaceports, deepwater seaports, freight rail terminals, passenger rail and intercity bus terminals, rail corridors, waterways, and highways.

Traffic data was collected and existing conditions were evaluated including capacity, levels of service (AM and PM peak hours) and safety. Existing intersection and highway segment levels of service were typically LOS F along the Gandy Boulevard corridor…
