swarming with zoom lenses trained on the Trinity Rockstar. The 161foot (49-meter) motoryacht might as well have been a porpoise caught in a net, brought from a slow, run-of-the-mill tow to a sudden, scary halt. Above her was the Broad Causeway drawbridge, which had just crashed onto her arch and superstructure. The yacht sat trapped in the metal snag and media frenzy that replayed for hours on South Florida news stations.
Nobody was hurt in the December 2014 incident, which the Florida Fish and Wildlife Conservation Commission attributed to a hydraulic failure in the bridge. Then additional details emerged, and the story became troubling on a deeper level.
The bridge was 63 years old, more than a decade past the 50-year mark that many American bridges were built to last. In 2010, the Florida Department of Transportation (FDOT) had labeled the bridge “functionally obsolete.” Offcials of the municipality responsible for repairs had spent six years debating when and how to fx things, including stripping support columns to bare metal for refurbishment. Council members had fnally settled on a January 2015 start for the $11.5 million project.
The bridge crashed onto scheduled to begin.
Infrastructure repairs being put off until the last minute, and then at least a few years more, is a common tale across the United States. One week before the Broad Causeway incident, “60 Minutes” aired the blistering report “Falling Apart,” describing how nearly 70,000 U.S. bridges—one in nine—is “structurally defcient.” In the language of infrastructure management, that’s actually a worse descriptor than the functionally obsolete one used for the Broad Causeway bridge. While a functionally obsolete bridge may have inappropriate lanes for current traffc needs, a structurally defcient bridge has deterioration to one or more major components.
Given the current state of America’s infrastructure and Florida’s reliance on bridges, should yachtsmen worry that the Broad Causeway incident is the frst of many to come? Do yachtsmen need to look up with a wary eye whenever they pass beneath a span? Offcials say no, but then again, they also said the Broad Causeway bridge still had time to spare. A examination of the most recent data for bridges in Fort Lauderdale shows there may indeed be reason for concern. Florida, where yachts encounter more bridges than anywhere else in America, has 243 structurally defcient bridges and another 1,760 that are functionally obsolete, according to the Federal Highway Administration. While cause for attention, that’s actually good, percentage-wise, compared with the rest of the country, thanks in part to Florida’s use of gas taxes and other dedicated funding for repairs and replacements. Florida’s bridges also see less weather stress than, say, bridges in the Northeast that endure winter freezes. Looking at the national picture, Florida’s bridge ratings are the stuff of envy.
Zooming in on the superyacht mecca of Fort Lauderdale shows that, of the several hundred bridges in Broward County, 14 are structurally defcient and 109 are functionally obsolete, according to the Federal Highway Administration.
The good news is that none of the bridges yachtsmen regularly cruise beneath to get from open
water to Fort Lauderdale’s prime marinas and reft yards are classifed as structurally defcient.
Two, however—Las Olas Boulevard bridge and Davie Boulevard bridge—are labeled functionally obsolete, just like the bridge that fell on Rockstar. Both are maintained by FDOT, which does not consider them a safety hazard.
“If it was an immediate danger situation, the bridge would be closed,” says Barbara Kelleher, public information offcer for the FDOT district that includes Broward County. “The movable bridges, by law, they’re inspected by our bridge inspectors once a year. That inspection encompasses not only the structure but also the mechanics, the hydraulics, the electrical system that operates the movement itself.”
The Las Olas Boulevard and Davie Boulevard bridges are rated functionally obsolete solely because of their traffc-lane widths, Kelleher says. Their status has nothing to do with parts that affect yachts during openings and closings. No projects are scheduled for rehabilitation or replacement, she adds, because the overall health indexes of both bridges are good. Functionally obsolete status is just one metric used in determining any bridge’s overall health index. Other metrics include suffciency rating and bridge age.
“You have to look at the health index,” she says. “If it’s healthy, there shouldn’t be a problem like that” Broad Causeway incident. Of course, that is a hope all owners and captains share, but a number of the key metrics FDOT reported in July 2015 for the Las Olas Boulevard and Davie Boulevard bridges are remarkably similar to those of the Broad Causeway bridge that fell on Rockstar. All three bridges are of similar vintage, built between 1958 and 1960. All three have suffciency ratings (on a scale of 0 to 100) below 70—with the Las Olas Boulevard and Davie Boulevard bridges scoring 13 to 18 points below the bridge that failed. All three bridges also have high health ratings, above 85 or 90 (again, out of 100).
When presented with these similarities, Kelleher again said yachtsmen should not worry.
“A small component of the suffciency rating includes structural condition, but there are many components that make up a bridge structural condition and many other factors that make up the entire suffciency rating. It would not be appropriate to draw a correlation between the condition of a hydraulic lift system and the suffciency rating,” Kelleher said, relaying comments from an FDOT bridge engineer. “Also, the Las Olas Boulevard ICWW bridge and the Davie Boulevard bridge on the New River do not have hydraulic lift systems. These two bridges have mechanical lift systems that are made up of motors and gears. Based on the latest biennial inspections, the mechanical lift systems on both of these bridges are in good condition.” Trying to get a clear-cut answer about the condition of bridges that yachtsmen regularly use is further complicated by the sheer number of entities that own and maintain the structures. The Las Olas Boulevard and Davie Boulevard bridges are just two among hundreds within Broward County maintained by a variety of state, county and local entities.
Overall, Kelleher said, the number of functionally obsolete and structurally defcient bridges is going down county- and statewide
because agencies at all levels are dedicating funding to fxes. Broward County’s recent scores for the bridges it maintains are noteworthy: As of April 2015, all had an average health index of 92 out of 100, with none structurally defcient. That, Broward County says, makes its bridges—including the 3rd Avenue, Andrews Avenue and 7th Avenue bridges regularly used by yachtsmen—among the safest in Florida.
“It’s very unusual for a large municipality,” Ahn Ton, director of the Broward County Highway and Bridge Maintenance Division, says of the high scores. “Nationally, we see less and less funding from the federal funding department to replace our bridges, so locally, in Broward County, we’ve had to expend a signifcant amount of funding to replace that.”
While various offcials continue to assess and debate what work will be done, and when, on South Florida bridges, yacht owners and
Florida East Coast Railway bridge that crosses the New River in Fort Lauderdale. Because the bridge
has just 4 feet of clearance when down, yachting enthusiasts aboard everything from Boston Whalers
to Feadships need it open to access many of the city’s marine businesses, including Lauderdale Marine
Center, Bradford Marine Shipyard and Westport Yacht Sales.
Right now, the bridge is never closed more than one hour, 45 minutes during any 12-hour period, Purcell
says. That accommodates as many as 14 freight trains daily. But a proposal by All Aboard Florida to add
commuter trains for high-speed service from Miami to Orlando is expected to bring crossings by 32 freight
and commuter trains a day, at least once every hour, for at least 10 to 15 minutes at a time—creating a
bottleneck for yachts that could severely affect the shipyards and marinas on the other side.
“We’re not trying to stop the train,” Purcell says. “We’re trying to build infrastructure and offer
solutions that help commuters, but not at the cost of the marine industry.”
A draft study by the Federal Railroad Administration concluded the new trains would have a negligible
effect on yachtsmen, and when
month test to see if adding a bridgetender would help. MIASF was looking into a smartphone app, too.
Replacing the nearly 40-year-old bridge is not an option, Purcell said, because freight trains can’t
handle steeper inclines that would raise the clearance level for yachts. And even if all parties agreed
today to build a new bridge, he said, the project would take five to seven years.
All Aboard Florida service is scheduled to start well before then, which means yachtsmen will have
to wait and see how the new rail traffic affects openings and closings, as well as the four-decade-old
drawbridge mechanism.
“If it breaks in the down position,” Purcell said, “we also have a big problem.” — K.K.
