The FIU bridge, meant to cross eight lanes of traffic at a particularly dangerous intersection in front of the school, was designed to double as an amenity deck and would have featured a bike lane for students. Instead of being constructed in situ, the span that collapsed was built on temporary supports on the side of the road, and rotated 90 degrees into position on March 10th. Using this “Accelerated Bridge Construction (ABC) method” to build the bridge’s superstructure elsewhere was touted as a way to cut costs and minimize disruptions to traffic below. According to a press release from LIU, the bridge would have also been the first in the world to have been constructed from self-cleaning concrete. It’s currently unclear whether the construction methods used to build the span played a part in the collapse, which flattened the cars underneath at the time. Miami-Dade Mayor Carlos Gimenez had said earlier that day that the bridge had just successfully completed stress testing. In a statement given to the Miami Herald, FIU President Mark Rosenberg said that the testing was done in accordance with best practices. “I know that tests occurred today. And I know, I believe, that they did not prove to lead anyone to the conclusion that we would have this kind of a result. But I do not know that as a fact.” Florida Senator Marco Rubio took to Twitter to discuss the work being done on the bridge before its collapse, saying “The cables that suspend the Miami bridge had loosened & the engineering firm ordered that they be tightened. They were being tightened when it collapsed today”. The engineering firm Rubio is referring to is FIGG Bridge Design, who were collaborating with Munilla to build the bridge. While the span was to be supported by steel suspension cables installed from a central column later on, Rubio may have been referring to tension cables inside of the bridge itself. It's unclear what form of temporary support was holding up the bridge at the time of the accident. At the time of writing, it’s unclear why engineers had chosen to stress test the bridge while allowing traffic to pass underneath, or if the cable tightening had played a role in the failure. The $14.2 million bridge, financed through a US Department of Transportation TIGER grant, had originally been slated to open in early 2019.

Architects at Boston's CambridgeSeven have recently completed work on a sea study lab that includes the world's largest hurricane simulator. The 86,000-square-foot space, part of the Rosenstiel School of Marine and Atmospheric Science at the University of Miami, was pummeled by 2017's Hurricane Irma, but its ultra weatherproof design enabled the building to survive the storm relatively unscathed.
Perhaps the most distinctive component of the facility, officially known as Marine Technology and Life Sciences Seawater (MTLSS) Research Complex, is its hurricane simulator. The two-story storm room holds the SUrge-Structure-Atmospheric INteraction (SUSTAIN) lab, three wave and wind tanks that researchers deploy to ravage model cars and homes so they can better predict the path of hurricanes and understand the physics behind storm strength.
During Irma, the facility was subjected to the conditions it was built to study, and after the Category 4 storm subsided, the wind and wave tanks became temporary homes for fish from other labs displaced by flooding. In spite of—or perhaps owing to—natural disasters like Irma, though, the MTLSS complex maintains a strong connection to the sea: Water from Biscayne Bay is filtered for heat and cooling purposes, as well as purified for use in the facility's overflow-resistant seawater tanks, which together hold 38,000 gallons. The entire three-story facility, which includes offices and classrooms in addition to labs, is raised 15 feet above ground, a flood-proofing must in Miami.A video released by the University of Miami goes on a deep dive into the facility:
What's more fun than a slide? Nothing, except for maybe a supersized version of the playground standby.
Visitors to Miami's Aventura Mall get to ride exactly that. Designed by Belgian artist Carsten Höller, the 93-foot-tall pair of double-barreled slides run clockwise-counterclockwise, and can be ridden solo or with a buddy. Visitors ascend a spiral staircase to reach the top of the slippery titanium steel slides, which whisk riders away at dizzying speeds, up to 15 miles per hour. With their industrial finish and slightly goofy steampunk massing, the slides look less Miami, more City Museum—but a whole lot of fun nevertheless.
The slide-sculpture, officially Aventura Slide Tower, is part of the Aventura Mall's recent expansion, a three-level indoor-outdoor space designed around experiential art from the likes of Louise Bourgeois, Jorge Pardo, Ugo Rondinone, and others.
Mall-goers shared their reactions to the mega-slide on Instagram. Here's a real-time ride:
