October was a crowded month for the Rickenbacker Causeway. There was a county commission vote on Bear Cut Bridge. There was a pop-up across from MAST Academy with a sandbox model of a raised roadway, and the Village Council scheduled a workshop on that same concept. The County also scheduled an initial land-use reading for the Miami Seaquarium site. Taken together, it looks like the road onto the island is about to change.
None of these steps picked a design or approved construction. What October did settle is the order in which things can happen. Nearly every part of that order runs through one bridge built in 1944, and a study on that bridge isn't due until March 2027.
The October 6 Vote Signed Up for the Study
On October 6, 2026, the Miami-Dade Board of County Commissioners adopted Resolution R-814-26. Commissioner Raquel Regalado was the prime sponsor. The resolution approves a memorandum of agreement with the Florida Department of Transportation for the Bear Cut Bridge Project Development and Environment study, known as the PD&E study, which is the federal environmental review a major bridge project needs before it can go to design. According to the County's staff memo, the agreement is needed to keep the project eligible for future federal funding. The memo also commits the County's Department of Transportation and Public Works to carry out whatever commitments come out of the environmental process before the project moves to construction.
The resolution doesn't choose between repairing the bridge and replacing it, and it doesn't fund any construction. The memo states there is no immediate fiscal impact. It also says the study is "fully funded with Rickenbacker Causeway Toll Revenues." Since October 1, 2025, those tolls have been $3.25 by SunPass and $6.50 by Toll-by-Plate for a two-axle vehicle, and Key Biscayne residents can buy an annual plan for $72, according to the County's toll page. In other words, the island's own crossings are helping pay for the study that decides the bridge's future.
Why One Bridge Sets the Schedule for Everything Else
The County's Bear Cut project page calls the bridge "the only mainland access point for the Village" and a designated emergency evacuation route. Its history explains why the study exists at all. The bridge opened in 1944 and was widened in 1983. In 2022, an FDOT load rating report found distress and corrosion in the beams installed in 1983 and recommended a 20-ton load limit. A repair project in 2023 restored spalled concrete, reinforced piles and fixed damaged beams, which kept that limit from being imposed. Then in June 2024, FDOT gave the bridge a sufficiency rating of 37.3 out of 100, a score the County says may qualify it for replacement. The commission memo calls the bridge "functionally obsolete" and says it needs frequent significant repairs to stay in safe operation.
The study covers a 1.1-mile corridor from Arthur Lamb Jr. Road to the Crandon Marina Access Road. It will weigh several alternatives: a no-build option that keeps up repairs, a major rehabilitation, or a replacement, along with parallel alignments, different structure types, wider shoulders and better bicycle and pedestrian facilities. It started in October 2024 and is expected to finish by March 2027. Design work begins only after that.
One scheduling detail can cause confusion. The County's broader Rickenbacker Causeway page still shows an older timeline, with design expected in spring or summer 2025 and construction in 2027. The dedicated Bear Cut page has the later schedule, and the October resolution matches it: the study comes first, then design, then construction.
The Shoreline Is Designed to Come After Bear Cut
The Shoreline gets most of the attention because it's the most visible idea for the causeway. Commissioner Regalado proposed it about a year ago. As Islander News reported from the Village's April workshop, the concept is a split-level roadway across Virginia Key. Its ramps would start near the Rusty Pelican Marina entrance and end where Bear Cut Bridge begins. Through traffic and fast bicycle pelotons would use the upper level. The existing road below would become four lanes at 30 mph, with access to Virginia Key, the Miami Seaquarium site, Miami Marine Stadium and MAST Academy, and with roundabouts at the turnoffs. An earlier Islander News account puts the viaduct at 28 feet high, with two lanes in each direction and 10-foot emergency shoulders on both sides, built for an estimated 28,000 daily through vehicles.
The physical limits matter as much as the drawings. The petrified groves near Crandon Park are a strict no-touch zone, so the structures can't extend past them. A 102-inch sewer pipe can't be moved and has to be designed around. The William Powell Bridge would stay as it is. On timing, the April report says the Shoreline "could start after the Bear Cut Bridge is replaced, if that decision is finalized." Regalado herself has said she hopes the Shoreline work will catch up with the federal environmental review for Bear Cut.
So the Shoreline depends on the bridge study. If the study recommends rehabilitation over replacement, the opening the concept was planned around becomes much narrower.
What the Village is paying for now is a feasibility study. The Council approved up to $950,000 last November, and Mayor Joe Rasco argued that the causeway is the island's issue to solve. The study has seven steps. The design team includes Juan Mullerat of Plusurbia, Javier Manso of HDR, and the Rebel Group, which is studying funding and revenue options. Regalado described the effort as "a stress test of this idea of The Shoreline." Village Manager Steve Williamson put the open questions this way:
"Is the concept feasible? Is it financially feasible? Is it operational feasible?"
In April, two of the seven steps were done, and the study was expected to wrap up in October. On October 15, the Key Biscayne Community Foundation held The Shoreline Pop-Up at 3602 Rickenbacker Causeway, directly across from MAST Academy. Visitors could see project boards and a scaled sandbox model and give feedback "before the plans are finalized," as Islander News described it. The Village Council also put a dedicated workshop on The Shoreline Concept on its calendar for Tuesday, October 27, at 6 p.m. in the Council Chamber. It was scheduled as a workshop, not a vote.
The Seaquarium Has Its Own Approvals to Get
The Seaquarium redevelopment is the one corridor plan that doesn't wait on Bear Cut. It still has several approvals ahead. WLRN reported on October 15 that developer David Martin's $100 million plan had an initial land-use reading set for October 20. The lease vote hadn't been scheduled, and a required zoning change had no date either. The proposed marina still faces permitting questions, including seagrass and seafloor-survey issues. Under the draft lease, Martin can renegotiate the deal if the marina isn't permitted. In November 2025, the Miami Herald reported that Martin planned to open the redeveloped property by 2030. That date was a stated goal at the time, made before the remaining approvals were in place.
The two projects connect on the ground. The Shoreline's lower road was drawn with an access point for the Seaquarium site, and the April presentation noted that the site's entrance might move.
Where Each Plan Stands Going Into November

For island owners, the causeway timeline often comes up when deciding when to sell or renovate, and how to talk with buyers who ask what's ahead on the Rickenbacker. If you'd like to go over what the Bear Cut study schedule means for your plans, Renier Casanova and the Casanova Group are happy to talk it through. Request a private consultation.
