Martin MPO presents Martin Moves 2050 needs plan; model flags 29 overcapacity corridors by 2050

Summary
MPO staff and consultant TYLN presented the Martin Moves 2050 needs assessment at the May 12 meeting, reporting that modeling and public input together identify about 29 roadway corridors projected to be overcapacity by 2050 and a multi-modal list of transit, roadway, freight and resiliency projects.
MPO staff and consultant TYLN presented an update on the Martin Moves 2050 long-range transportation plan (LRTP) needs assessment at the May 12, 2025, Martin County MPO meeting. The presentation summarized public outreach, technical analyses and the preliminary list of projects needed by 2050, and identified next steps toward a draft cost-feasible plan.
“MPO staff started this process back in April of last year,” project manager Ricardo Vasquez told the board, noting the MPO had approved the public involvement plan and collected community input. Consultant Vikas Jain of TYLN said roughly “about 300 complete surveys” were received and that the public flagged traffic congestion, safety and limited transit as the top issues.
Technical work used the Treasure Coast Regional Planning Model (TCRPM) to evaluate existing-plus-committed projects against 2050 population and employment forecasts. The consultant reported roughly 15–16 congested segments today and about 29 roadway corridors predicted to exceed capacity in 2050. The consultant said some corridors would need widening, while others could be addressed with Transportation Systems Management & Operations (TSM&O) or Intelligent Transportation Systems improvements.
The needs plan groups projects by mode. Highlights presented to the board included fleet replacement and new bus stops for transit; 14 corridors recommended for roadway capacity projects (some widening from two to four lanes and a few from four to six); Strategic Intermodal System improvements on I‑95 and SR 710; TSM&O corridors for congestion management; resiliency projects (sea-level adaptation and drainage stabilization); freight improvements including truck parking and shoulder widening; and aviation projects adopted from the airport master plan.
Board members asked about specific items such as water taxi feasibility, North Sewell’s Point Road capacity listing, and which projects in the needs list already had committed funding. County staff (George Zama, deputy director of Public Works) explained that the “existing plus committed” network includes TIP and capital improvement projects and developer-funded extensions. The consultant and staff said they will reconcile project lists and refine the congestion corridors with FDOT’s ongoing TSM&O plan.
Next steps announced: MPO staff will incorporate feedback from advisory committees and the MPO board, perform project cost estimates and a 25-year revenue forecast, and assemble a draft cost-feasible plan. An open house on the draft cost-feasible plan is expected in August 2025, with committee presentation in September and adoption anticipated in late October 2025.
Discussion vs. decision: this meeting recorded a technical presentation and questions from the board; staff indicated the needs plan will be updated and returned to the board for adoption later in 2025. No final adoption of the cost-feasible LRTP occurred at this meeting.
