• The I-275 corridor is in the heart of the Tampa Bay area

• This project increased the capacity of the corridor by providing 4-lanes in each direction and improving vertical and horizontal geometry.

Outstanding Project Award: I-275 Reconstruction D/B, FDOT District 7

• This project sets for managed lanes (Tampa Bay Express) and future intermodal transit

• The majority of this project is part of the “ultimate” alignment of the corridor and was constructed using cement concrete paving to reduce the long-term maintenance and increase the lifespan of the corridor for future generations of automotive users.

Page 27: WELCOME TO ORLANDOc.ymcdn.com/sites/ Outstanding Project Award – Major Projects Category I-275 Reconstruction D/B, FDOT District 7 • The I-275 corridor is in the heart of the Tampa

• The greatest challenge for this project was the construction of proposed higher bridges within the footprint of existing bridges, and without impacting the operations of the existing corridor.

Okeechobee Road PD&E Study, Miami-Dade County

Project Highlights

• 10-mile SIS with up to 90,000 vpd and 15-20% trucks

• 5 miles urban, 5 miles rural

• Recommended alternative included both low cost TSM&O

improvements as well as major build alternatives for the

project segments

• Developed and recommended two new grade separated

intersections (three-level)

• Successfully prepared a Net-Benefit Section 4(f) for the

relocation of Bernie Wilson Park (a First in Florida!)

• The team divided the project into five separate construction

projects, set a schedule for each and was successfully able to

meet the schedules for the 5 design jobs (all currently in the

design phase)

• $328M Construction Cost; $67M R/W Cost

Project Challenges

Partnering

• Held over 60 meetings with

stakeholders and the public

• Several solutions were conceived as a

direct result of coordination

• Created a Project Advisory Group to

vet project alternatives

• SFWMD aided in development of

feasible solutions due to impacts to two

primary canals (C-6 and C-7)

• Partnership with City of Hialeah

Gardens helped develop mitigation

strategies and establish a Net Benefit

for impacts to Bernie Wilson Park

• Coordination with 10 adjacent projects

Operational and Geometric Deficiencies

• SIS facility that is both a major freight corridor and also an important

access route for both commercial/industrial and residential communities.

- Competing maneuvers between the high density residential traffic and

large industrial and commercial areas

• Limited Access Points (class 2 facility)

• Frontage Road and NW S River Drive

parallel Okeechobee Road less than 150

feet apart

- 3 signalized intersections within 460 ft.

- Creates operational issues

• Miami Canal (primary SFWMD canal)

directly abuts Okeechobee Road further

complicating improvements

Page 40: WELCOME TO ORLANDOc.ymcdn.com/sites/ Outstanding Project Award – Major Projects Category I-275 Reconstruction D/B, FDOT District 7 • The I-275 corridor is in the heart of the Tampa

• Highly congested urban corridor

• Rural segment with high vehicular speeds and high percentage of heavy trucks

• Complete reconstruction to rigid concrete pavement

• Very high traffic volumes concentrated at 4 key project locations

• Multi-level intersections required to address current and future travel demand

Project Complexity

• Okeechobee AADT: 90,000 VPD – widen to 4 lanes per direction • Only access point for several major traffic generators

• Impacts to Bernie Wilson Park

• Section 4(f) Resource

• 1.23 acre community park serving the adjacent community

• Project required complete removal of the park

• Preparation of Section 4(f) Evaluation

• FHWA concluded no feasible and prudent avoidance

alternative exists

• Identified several mitigation sites considered by the City of

Hialeah Gardens to be an improvement to the existing site

- Larger, more accessible, could accommodate all

existing features and future growth

• City of Hialeah Gardens determined the mitigation to be a Net

Benefit to community – FHWA concurred

• Downgraded documentation to a Programmatic Net

Benefit

- Saved one year from the schedule

- No US Department of Interior review and approval

- No elevation of the Class of Action to an EA or EIS

Project Background

• Heavy truck traffic on SR 585 through Ybor

City between I-4 and the Port of Tampa

divided and eroded this National Historic

Landmark District for decades.

• Completion of I-4/Selmon Expressway

Connector by FDOT made it possible to

divert truck traffic off SR 585 and provided

the opportunity for corridor enhancement.

• Major Stakeholders:

• FDOT District Seven

• City of Tampa

• Ybor City Development

Corporation

• Barrio Latino Commission
