Longboat Key only has two entrances by road — and both are drawbridges. The future of one is up for debate.
To the north, the Longboat Pass Bridge has been determined “functionally obsolete” by the Florida Department of Transportation. Built in 1957, the bridge has slim pedestrian lanes and aging materials.
FDOT held public workshops in March to present three options to rebuild the bridge. Debate among commissioners, community members and the FDOT ensued in the following months.
The three options included two bascule, or drawbridge, options — a low-level bascule at 23 feet high and a mid-level bascule at 36 feet high. The third option was a high fixed-span bridge, which was proposed as 78 feet high. This would be a bridge tied for the fifth-tallest bridge in Florida.
The lowest build alternative is expected to cost between $147 million and $158 million. When building a little higher with the mid-level bridge, the cost would be around $153 million to $165 million. Finally, the fixed-span alternative would be the cheapest option at around $93.3 million, since it eliminates the drawbridge feature.
FDOT could also choose to make repairs to the existing bridge, which happened in 2005 and 2020. FDOT covers the cost, in either building or rehabbing, leading Longboaters to focus on the height options.
Residents from the Northgate condominium complex to the west of where the new bridge would be built raised concerns about the fact that any new bridge alternatives would land about 36.5 feet away from the condos.
Another factor made clear by residents and town commissioners: The high fixed-span bridge would not fit the community character of Longboat Key.
Further conversations with FDOT and community groups led the Longboat Key town commission to recommend the mid-level bridge, and FDOT worked with the town to find ways to slightly cut the width of the bridge to give the Northgate complex more space. As of early October, the project is under study; a decision is expected in late 2025.
The Observer analyzed eight other bridges in the Sarasota-Manatee area as a comparison to the three options for Longboat.
