Introduction

This Design Build project widens a six-mile section of SR 417 Seminole Expressway from Aloma Avenue (SR 426) to SR 434 in Seminole County. The project will increase the number of travel lanes from four to eight. Additional work includes pavement milling and resurfacing, new drainage ponds, bridge widening, bridge reconstruction and roadside safety enhancements. Currently, the project is in the Conceptual Design Phase of the Design Build Project Development process.

Noise Studies are performed in the PD&E phase and the Design phase, and reevaluated if there is a major change in design to the roadway. A noise wall evaluation for this project is currently underway. Noise specialists will use the approved federal and state procedures for evaluating whether noise abatement or reduction would benefit property owners. The analysis identifies noise abatement locations and the proposed method to reduce traffic noise, including walls. The findings will be documented in the Noise Study Report.

Project Background

State Road 417 is a hurricane evacuation route and a major north/south corridor for commercial and private transportation. The interchanges at Aloma Avenue, Red Bug Lake Road, and State Road 434 all serve as important east/west connections. Also, the Cross Seminole Trail crosses over the project area in two locations. Land use adjacent to this project and within the general vicinity of State Road 417 consists primarily of residential and commercial development.

The original Project Development & Environment (PD&E) study was initiated in November 2005 for State Road 417 from the Orange County Line to the Rhinehart Road Interchange. A Public Hearing was held on April 17, 2007, to discuss the project status and to offer project stakeholders the opportunity to review project documents and provide comments. Throughout the PD&E study phase, FTE representatives made presentations to various agencies and groups in adherence of PD&E commitments which include:

  • Coordinate with agencies
  • Conduct a noise evaluation and abatement (if necessary)
  • Minimize property impacts
  • Protect threatened and endangered species
  • Mitigate freshwater wetland impacts

During the project’s PD&E phase, it was determined that widening of the existing roadway would result in increased traffic noise.  As a result, it was recommended that noise walls be reevaluated during project design at multiple locations along State Road 417. Pursuant to the FDOT Design Manual (FDM), Chapter 264 Noise Walls and Perimeter Walls, noise abatement identified as reasonable and feasible in the Noise Study Report (NSR) developed as part of the PD&E documentation, will be reevaluated. This reevaluation will further assess noise abatement and determine if it is still reasonable and feasible based on abatement criteria and project design. Results of this reevaluation will be documented in an addendum to the project NSR. Results will also be presented and discussed with affected stakeholders as outlined in FDM Chapter 264 and the FDOT PD&E Manual, Part 1, Chapter 11 (July 2020).

Study Area

The project limits are from Aloma Avenue (State Road 436) to State Road 434, in Seminole County, Florida. The total project length is approximately 6.6 miles (see project location map below).

EXISTING CONDITIONS

The existing mainline configuration of SR 417 in the project area consists of two 12-foot lanes, a 10-foot outside shoulder, and an 8-foot inside shoulder in both the northbound and southbound directions. Additionally, there is a guardrail adjacent to the southbound inside lane and a 64-foot grassed median.

PROPOSED DESIGN

The proposed Turnpike mainline configuration consists of four 12 -foot lanes, a 10-foot outside shoulder, and a 12-foot inside shoulder in both the northbound and southbound directions. Most of the proposed widening will occur along the inside lanes, with only five feet of widening to the outside lane. Additionally, a concrete barrier wall located in the median will separate opposing lanes of traffic.

Primary roadway improvements will consist of the mainline widening, additional mainline improvements will include the following: enhancements to existing stormwater ponds, upgrades to the Intelligent Transportation System, construction of noise walls in areas that meet FDOT criteria, installation of roadway lighting, enhancements to roadside safety features, and widening and/or replacement of mainline bridges.

INTERCHANGE IMPROVEMENTS

Aloma Avenue Interchange:

  • Replacement of existing SR 417 bridges over Aloma Avenue
  • Two additional right turn lanes along the southbound off-ramp
  • An additional left turn lane along the northbound off-ramp
  • An additional eastbound right turn lane along the southbound on ramp
  • Pedestrian and bicycle accommodations including:

Eight-foot pedestrian sidewalks on each side

Five-foot bicycle lanes which are separated from the travel lane by a two-foot buffer

  • An additional westbound thru lane
  • An additional eastbound left turn lane

Red Bug Lake Road Interchange:

  • Modification of existing SR 417 bridges over Red Bug Lake Road
  • An additional right turn lane along the northbound off ramp
  • An additional eastbound left turn lane

State Road 434 Interchange:

  • Modification of existing SR 417 bridge over SR 434
  • An additional left turn lane along the southbound SR 417 off ramp
  • An additional left turn from eastbound SR 434 to northbound SR 417

Environment

A State Environmental Impact Report (SEIR) was completed and approved in 2007. The PD&E Study is being reevaluated to determine whether the alternatives, impacts, existing environmental factors, and mitigation measures set forth in the 2007 SEIR remain applicable, accurate, valid, and meet state requirements. For more information, please view the  FDOT project development process video.

Innovation

FTE is at the forefront of planning for a safer, more efficient, and technologically advanced transportation system for the future. FTE continually seeks opportunities to integrate emerging transportation technologies that can help reduce congestion, create mobility choices, minimize environmental impacts, and improve safety. FTE also recognizes that connected and automated vehicle (CAV) technologies hold unprecedented opportunities for enhancing mobility and increasing safety on our roadways.
