The Tarpon Dock Bridge in Panama City is the only working drawbridge in northwest Florida and one of a few remaining in the state. It has one primary enemy, though: Thermal expansion.

Steel likes to stretch out when it gets hot, and the bridge, for all its quaintness, is made of steel. Sailors on their large boats may enjoy heading out into the bay during the blazing summer months, and while the bridge may open to let them out of Massalina Bayou, it sometimes has trouble closing.

When the drawbridge is opened, the metal span is freed from a closed, locked state. While up in the air, the metal on the span expands and shifts slightly. When the bridgetender goes to securely close the bridge, a metal locking "lip" can't latch, preventing the bridge from locking securely.

The most recent bridge closure caused by the heat was during the weekend of Aug. 7.

City officials previously told WMBB that the Panama City Fire Department and others have to come spray the bridge with water so it can cool down and compress. The bridge, built in 1951, has also been exposed to coastal salty air and seen continuous use over the past 75 years.

Combined with the fact that it previously operated under a mechanical system that later transitioned into a hydraulic system in the 1990s, it isn't hard to imagine that the bridge's aging mechanisms may not be in a pristine state.

Panama City is moving forward with a $1,050,000 state appropriation with a local matching amount of almost $150,000 to move forward with improvements and fixes to the bridge. This involves a mechanical and electrical overhaul and a specialized heat-deflecting thermal coating.

The final design is set to be complete by November, with much of the design already being under review by the Florida Department of Transportation by Aug. 10. Anticipated construction dates are currently set to extend into Spring of 2027, according to a city website on the project.

In conjunction with the bridge update is the replacement of the current water pipe that is providing water to residents in the cove. It's currently underwater, where it's vulnerable to passing ships and corrosion; the city would like to put it underground. This is expected to cost around $1 million.

Old editions of the News Herald show that the bridge was found to have structural issues in 2011, leading to a reduced weight load of 5 tons, down from 28 tons. This lasted 10 months and led to large vehicles being unable to use the bridge. The bridge was restored to full capacity in 2012.

If it's such an expensive piece of infrastructure, why does the government keep paying to restore it?

According to a funding initiative request filed by state Sen. Jay Trumbull, Tarpon Dock Bridge is essential for first responder access to The Cove. Additionally, it describes the bridge as being crucial to evacuation and egress while serving as a major utility corridor.

The funding request also says the U.S. Coast Guard requires access for vessels into Massalina Bayou. A low-fixed bridge would permanently block tall-masted ships from entering or exiting the bayou.

There's also the history of it all.

The bridge gets its namesake from the SS Tarpon, an 1887 steamship that carried goods to Panama City from across the Florida Panhandle and that sank during a storm in 1937.

Documents on file with the public library show that the early 1900s were a period of growth for the city. Residents moving into a new neighborhood, what is now called The Cove, would find their access to downtown quite limited. The city would award the contract to build the original bridge, a narrow timber bridge 10 feet above the water, in 1910.

The bridge's construction prompted a residential boom in The Cove, according to old newspaper accounts. Vehicle traffic would increase with the city's population in the 1920s, and the old timber construction simply wasn't meeting the demand.

In 1928, the old bridge would be demolished to make way for a new, sturdier, wider bridge across Massalina Bayou, gleaming from files at the library. Heartier materials were meant to make this new bridge withstand harsh coastal conditions and more weight from vehicles.

It stood for over two decades, but ultimately was condemned after structural deficiencies in 1950. The modern steel and concrete Tarpon Dock Bridge began construction in 1951 at an estimated cost of $250,000.

Officially, the bridge was named Frank M. Nelson, Sr. Bridge in memory of a local pioneer; however, the name appears not to have stuck over the years. Modern references found by a reporter simply referred to the bridge as the "Tarpon Dock Bridge." The 300-foot-long single-leaf lift span bridge brought about an interesting local tradition of bridgetenders.

They would raise and lower the bridge, working out of a tiny white office situated at its peak. The News Herald profiled some of these bridgetenders.

The first bridgetender was Basol P. Davis, who reportedly worked 12-hour shifts seven days a week. After he died, a group of city employees would start the Nelson BridgeTenders and contract to staff the bridge 24/7.

The iconic and somewhat unusual bridge would make its way into Hollywood. An undated, but modern-looking clipping of the News Herald says the site was picked by the Florida Film Commission for a Harley-Davidson commercial.

A reporter in 2026 was unable to confirm whether the shoot took place (there are no online mentions).

In June of this year, tea company Pure Leaf would use the bridge for a commercial. A large banner draped the bridge while it was in the up position in celebration of National Iced Tea Day.

Readers could say that the Tarpon Dock Bridge is a vital link between Panama City's past and present. Officials hope the planned upgrades will preserve the historic drawbridge and keep it serving residents, first responders and boaters for years to come.
