A Master Plan identified a Locally Preferred Alternative (LPA) for the corridor … This LPA was adopted by Broward County and approved by FHWA The “corridor” LPA is advancing through two separate projects: ● ●
Project Limits To Naples To Port Everglades/Airport Project Limits To Miami
The Planning “Vision” for I-595 Reversible Lanes Transit Facility Ramp Braid
Project Need • Broward County has been one of the fastest growing urban areas in the US • Only east-west expressway in Broward County • Strategic Intermodal Corridor • Existing AADT >180,000 vpd • 2034 AADT >300,000 vpd
Strategic Intermodal Corridor • District 4 SIS – Growth Management Priority • Truly Multi-Modal Corridor • I-75 & Sawgrass Expressway • I-95 & Florida’s Turnpike • Fort Lauderdale-Hollywood International Airport • Port Everglades • Connection to Tri-Rail and Amtrak • Proposed Transit Facility • Broward County Greenway
Key Components • Transit Facility • Highway Improvements • Reversible Lanes • Ramp Braids • Turnpike Interchange • CD (Collector-Distributor) System • SR 84 Continuous Connection • Auxiliary Lanes
PD&E Study • Unique project due to complexity and integration with other projects • Overall project cost >$1 Billion • High profile project with interest by many agencies, municipalities, residential communities and businesses • Priority corridor for roadway and transit improvements

Flamingo Rd. 136th Ave. C-D System Sawgrass Expressway / Interstate 75 To Port / Airport I-595 GP Lanes Reversible Lanes Florida'sTurnpike
PD&E Study Functions & Goals • Maintain Consistency with the LPA • Minimize overall project impacts • Develop a project that can be implemented • Build Consensus • Maintain project schedule • Advance corridor improvements • Phases of project funded
Why Invest in 3D Visualization? • Priority project • High profile complex project • Public Understanding • Design Decisions • Early validation of project alternatives • Public expectations
Why Invest in 3D Visualization? • Obtain (and maintain) buy-in from: • Management • Stakeholders • Agencies • Team members
Development of 3D Visualization • 12-mile Corridor • Focus Areas • Cost & Schedule • Developed one section of the corridor • Different Alternatives • Elevated Reversible Lanes • Transit Location • Ramp Braids • Community Concerns (Location, Noise, Visual) • Turnpike Interchange
Oh, Okay … Elevated Reversible Lanes ! Elevated Reversible Lanes ????
No, seriously … what is a “Braided Ramp” ??
The Results • Improved deliverable from the PD&E process • Better Integration of Transit Improvements • Helped identify the best use of existing right of way for both roadway and transit • Helped create a shared vision • Helped “visualize” the vision
The Results • Gained consensus • Project is being advanced • Better understanding of proposed improvements • Ownership of the PD&E alternative’s geometry = No major re-design • Selection of THE Preferred Alternative • BEAT the original aggressive project schedule!
Future Opportunities? Use the 3D Visualization as a Tool … • 3D Visualization at Key Milestones • Project Website • Future Public Meetings • Agency Coordination • Value Engineering / Design Review • Incorporate Data (GIS, Environment, Traffic, Land Use, Public Comments)
Future Opportunities? Develop a Project that can be Implemented • Constructability Review • Review key decisions • Facilitate a “seamless” transition to Final Design • Develop the phasing of multiple design/construction packages • Build onto the 3D Model • Review & evaluate constructability, compatibility and MOT between adjacent projects

PROJECT DEVELOPMENT & ENVIRONMENT (PD&E) STUDY • Martin County MPO’s #1 Priority • Engineering & Environmental Analysis • New Bridge Crossing on a New Alignment • Connecting Palm City with the City of Stuart • Alternate Route to SR 714 & the Palm City Bridge • Widen Existing Local Roads • Environmental Impact Statement (EIS) • Cost Estimate: $200 Million
SR 714 CR 714 Palm City Residential Community Proposed Bridge Palm City Bridge Environmentally Sensitive Area Kanner Highway Intersection Indian Street
PUBLIC INVOLVEMENT • Community Assessment Task Team (CATT) • Agency & Stakeholder Workshops • Continuous Public Involvement • Exchange Information Build Consensus • Community Characteristics Inventory & Database
CATT MEETINGS WITH STAKEHOLER GROUPS • Regulatory Agencies • Community Associations • Local Government • Community Services • Emergency Services
3D VISUALIZATION • Justification • Public Interest and Expectations • Participation in the process • Understand the alignment alternatives • Martin County MPO’s #1 Priority • 3D Model = Database • Design / Permitting • Construction
3D VISUALIZATION • Implementation • “In-house” Project “Hybrid” Project • Consultant Support • District 4 Commitment • Management Support • High Profile Project • Understanding of the Benefits
3D VISUALIZATION • Development • 4-mile Corridor • Key Areas to Reference (“Landmarks”) • Different Alternatives • Grade Separation • “Phased Development” for the Public
PUBLIC WORKSHOPS Interactive Stations: • Typical Sections • Alignment Alternatives • Evaluation Matrices • 3D Visualization
PUBLIC WORKSHOPS 3D Visualization … Allowed people to have a better understanding of the project, visualize the alternatives & make constructive comments.
What is a “Grade Separation” ??
