If you drove between St. Pete and Tampa early last week, you experienced it: traffic on our cross-bay bridges — especially the Howard Frankland Bridge — slowed to an agonizing crawl.
Why it matters: The jam was another product of Tropical Storm Debby's scrape past Tampa Bay, underscoring how much an indirect hit from a weaker storm can upend our lives and routines.
What they're saying: "Debby wasn't much of a storm," but still caused a storm surge that inundated roads, University of South Florida physical oceanography professor emeritus Robert Weisberg told Axios.
- "If we were to have an actual hurricane hit this region, it would be an actual disaster."
Driving the news: Debby brought a deluge of rainfall and gusty wind to Tampa Bay starting last weekend and continuing into last Monday.
- On the Howard Frankland, video shared by the Florida Highway Patrol showed waves thrashing the barrier wall and spilling onto the causeway.
- Early Monday, troopers learned part of the northbound shoulder had washed out in the storm, Sgt. Steve Gaskins told Axios.
- That led troopers to close all northbound lanes for much of Monday. The inside lanes later reopened, but the outside lanes stayed closed while workers fixed the shoulder.
- All lanes reopened about 4:30pm on Wednesday.
Yes, but: Commutes were miserable in the meantime.
By the numbers: On a typical weekday morning in July, it took about 6 minutes to drive over the 6-mile bridge, according to Florida Department of Transportation data.
- On Wednesday, while the two outside lanes were still closed, that drive time ballooned to about 31 minutes.
- The mid-day drive time tripled, from about 5.5 minutes to 17 minutes.
💭 Kathryn's thought bubble: It was so bad Wednesday afternoon (before the lanes reopened) that Google Maps recommended I go over the Skyway and up through southeast Hillsborough to get from south St. Pete to north Tampa.
- Somehow, that 62-mile trip was 15 minutes faster than the 36 miles it would take me to go over the Howard Frankland.
How it happened: A washout is sudden erosion from the foundation of a road being inundated with water.
- Debby brought about 3 feet of storm surge to Tampa Bay, bringing the water level almost as high as the road, Weisberg told Axios.
- The slopes next to the two washed-out areas were under construction and had only a temporary wall for wave protection, per FDOT spokesperson Kris Carson.
- Sections of the bridge with permanent walls were not damaged, she said.
- "We are confident the final construction will meet the standards for this type of roadway," she said.
