- How does the Project Development Process Work?
Depending on transportations priorities, available funding, and complexities of the job, a project’s progression from planning to construction may take up to 15 years. FDOT follows federal and state requirements throughout the project development and works closely with governmental agencies, partners and the local community to identify new projects and move them through the production pipeline. Planning, the Project Development and Environment (PD&E) study, final design, right-of-way acquisition, and construction are sequential phases of production for projects.
Planning – Anna Maria Island Bridge inspection reports have shown the current bridge is functionally obsolete and structurally deficient. Recognizing the importance of the vital connection between the barrier islands of Manatee County and the mainland it was determined that the possibility of a replacement bridge needed to be evaluated.
PD&E Study – FDOT substantially completed the PD&E study in 2010 and evaluated engineering, environmental, social, historical and cultural effects for this project. The study also estimated costs for future phases of production, including design, right-of-way, and construction. FDOT documented the need for the project and developed bridge improvement alternatives. The alternatives considered consisted of a No-Build Alternative, Rehabilitation Alternative, Tunnel Alternative, a Low-Level Bascule, Mid-Level Bascule, and a High-Level Fixed-Span Bridge. Because of engineering and environmental analysis, agency coordination, and public comments, the Recommended Preferred Alternative is to replace the existing Anna Maria Bridge with a High-Level Fixed-Span Bridge. On January 15, 2016, the Federal Highway Administration (FHWA) granted approval of the Finding of No Signification Impact (FONSI) for the proposed replacement of the Anna Maria Island Bridge. Approval of the FONSI means the FHWA determined that this project would not result in any significant impact on the quality of the human environment, thus completing the PD&E project phase.
Design –The design phases takes the PD&E Recommended Preferred Alternative conceptual plan and develops it into a formal set of construction plans that we will use to bid and build the project. The construction plans include the design of the bridge, drainage, signs, utility plans for necessary relocations, lighting, sidewalks, landscaping, as well as the road itself. This project is in the design phase and we should complete the design by late 2019.
Right-of-Way Acquisition – FDOT does not need to acquire property to build the Anna Maria Island Bridge replacement. In accordance with Florida statute, we will need to modify the existing Sovereign Submerged Lands Easement to reflect the replacement bridge location. Individuals can find additional information about FDOT’s right-of-way acquisition process at www.dot.state.fl.us/rightofway/Documents.shtm.
Construction – After design plans are completed, FDOT advertises the project for construction. Typically, construction work starts three to four months after FDOT hires the contractor (who must mobilize crews and arrange for equipment and materials). Construction jobs may take two to three years and sometimes longer depending on the complexity of the project. More information becomes available about a project’s construction schedule and crews’ approach of the work after FDOT hires the contractor.
- How high is the replacement Anna Maria Island Bridge?
The new bridge will have 65 feet of vertical navigational clearance. FDOT anticipates the maximum height of the surface of the roadway will be approximately 74 feet.
- Will the height of the bridge impact evacuations because of a high wind event such as a hurricane?
FDOT does not anticipate closure of the bridge due to wind speeds. The Anna Maria Island Bridge serves as a hurricane evacuation route in Manatee County and plays a critical role in the timely evacuation of the barrier islands. The Anna Maria Island Bridge provides the most direct evacuation route for the City of Holmes Beach and City of Anna Maria and serves as a secondary route for the residents of the City of Bradenton Beach and Longboat Key. All of Anna Maria Island and Longboat Key lie within the Manatee County Evacuation Zone A, which is evacuated first in the event of a hurricane.
- How wide is the replacement Anna Maria Island Bridge?
The new bridge will be approximately 69 feet wide. This includes a 12 foot travel lane, 11 foot shoulder, and 10 foot sidewalk in each direction. See graphic below for more information.
- Will the replacement bridge be longer than the existing Anna Maria Island Bridge?
There may be a small change, but the length is essentially the same. The new bridge will be approximately 3,150 feet long. We cannot provide an exact length at this stage in the design phase. For comparison, the existing bridge structure is 3,123 feet long.
- Where will FDOT build the replacement Anna Maria Bridge?
FDOT plans to construct the new bridge parallel and to the south of the existing bridge with approximately 14 feet between them.
- How steep is the replacement Anna Maria Island Bridge?
The Americans with Disabilities Act (ADA) requires a maximum longitudinal slope of 5% without landing pads. The new Anna Maria Island Bridge will have a maximum 4% longitudinal slope. This means that as someone travels across the bridge, the slope will be flatter at the bottom and top of the bridge. For comparison, the Ringling Causeway Bridge in Sarasota has a 5% slope and is steeper than the new Anna Maria Island Bridge.
- Will FDOT demolish the existing Anna Maria Island Bridge?
Yes, FDOT will demolish the existing bridge once we complete construction on the new bridge.
- Will there be impact to utilities by this project?
Yes, we will need to relocate some utilities as part of this project.
- Will the new Anna Maria Island Bridge impact any wetlands, seagrass or mangroves?
We are very early in the design stage and wetland surveys are not completed. Based on information gathered during the PD&E Study we anticipate approximately 1.2 acres of mangrove and 2.0 acres of seagrass impacts, both of which FDOT will mitigate. This accounts for the potential of temporary impacts caused by construction activities. FDOT will conduct additional surveys as the design phase of this project progresses to determine exact impacts. FDOT is considering several alternatives to mitigate for the proposed impacts including the use of off-site mitigation banks, on-site or near-site enhancement and creation areas, or a combination of these strategies.
