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.

New York City streets are a decadent mass of pedestrians, cabs, delivery trucks, and the crosstown bus, all scooting somewhere quickly. But even as rideshare apps are pushing more cars on the pavement, there's one green and steadfast transit option that's seeing a surprising surge in popularity.
Right now, the city's streets host 450,000 bike rides per day, an increase of 280,00 trips from 2005. To meet accelerating demand, the New York City Department of Transportation (DOT) promised on Monday to add 50 miles of painted bike lanes and ten miles of protected paths each year.
Over the last decade, New York has seen an explosion of bike infrastructure. Crain's reports that cyclists now cruise over 1,133 miles of bike lanes, up from a little over 500 miles in 2006. Of those, around 40 percent are shielded from automobiles by concrete or other physical barriers. These are the gold-standard tracks because of the protection they provide relative to painted paths.
But even this relatively robust network can't stop bike fatalities. Nine in ten cyclists killed while riding are killed outside of bike lanes. In response, the DOT plans to ramp up safety efforts in three Queens and seven Brooklyn neighborhoods where many bike fatalities and injuries occur.
Still, officials are optimistic that bikesharing, which was introduced only four years ago, will become further enmeshed in New York's urban fabric. City Councilmember Ydanis Rodríguez, who represents Upper Manhattan and serves on the council's transportation committee, would like to one day see free transfers between Citi Bike, the city's bikeshare system, and the MTA. (An annual Citi Bike membership costs $163.) Citi Bike broke ridership records with more than 70,000 riders on one day in June of this year, while last year, the system logged more than 14 million rides.
Despite their low cost relative to cars, and emissions-free crunchy-green aura that renders bicycles anodyne in most quarters, New Yorkers haven't embraced bike culture universally. On the Upper East Side last year, residents objected to bike lanes near a school, worried that speeding cyclists could mow down young ones. Though those crosstown lanes were ultimately approved, out in Corona, Queens, longtime Community Board 4 member (and unrepentant xenophobe) Ann Pfoser Darby called bike lanes in her neighborhood a waste of money, claiming they would be empty after President Trump deported the area's undocumented immigrants.
Miami’s infrastructure woes run deep, but the city has its eyes set on “huge cultural change”

Talk of “infrastructure” may be one of the few things—if not the only thing—that comes close to uniting Democrats and Republicans at the moment. It was transit infrastructure, of course, that literally united the states of America: originally with railroads in the 19th century and later with interstates and automobiles in the 20th. Today, however, some cities’ prevailing love affairs with the car have become rather one-sided.
Polluting air and clogging roads, vehicles choke our cities. Miami ranks fifth nationally and tenth globally for congestion, as residents spend 65 hours in traffic per year on average, according to INRIX, a global traffic researcher that uses big data. Adding real injury to insult, the state’s stretch of the I-95 is America’s most deadly, according to statistics from the National Highway Traffic Safety Administration.
There is a financial burden to excessive traffic too. INRIX estimates that congestion costs Miami drivers $3.6 billion per year (remember that figure). Additionally, drivers pay out an average of $628,000 every day in tolls, just for the privilege of using the Miami-Dade Expressway.
Cars aren’t cheap, but what is the alternative in an auto-dependent city like Miami? Director of the Department of Transportation and Public Works (DTPW) for Miami-Dade County Alice Bravo said that she wanted to make Miami a “car-optional community,” where people can get to “all the different regions within the county using reliable public transit that’s convenient and helps people save time.”
A plethora of schemes and projects are now occurring in and around the city, such as high-speed regional rail, local rail, bus, bicycle, and pedestrian routes, water travel, and carpooling. Miami has gone from having nothing concrete in the pipeline for years to everything happening at once, and this coincides with a development boom that is more tuned for urban living than previous waves of development.
Bravo said that the backbone of the infrastructure surge is the Brightline, a completely private, approximately $3 billion scheme by All Aboard Florida. The “higher-speed” (Note: not high-speed) rail service runs the 235-mile stretch from the Orlando airport to Downtown Miami. The new line will reduce travel between Orlando and Miami from four hours to two and a half, for about the same cost as driving.
Such a commuter-rail service may sound familiar: In the late 19th century, the Florida East Coast Railway (FEC) was developed by Henry Flagler. Flagler’s railway ran from Jacksonville and was dubbed the “eighth wonder of the world.” The commuter rail prevailed until the 1960s when the line was used to transport freight only, which it still does to this day. Unsurprisingly, then, All Aboard Florida is a sister company of the FEC and the new tracks will be laid along the existing lines.
Designing the Miami station, as well as those in Fort Lauderdale and West Palm Beach is Skidmore, Owings & Merrill (SOM) who are working with Miami-based Zyscovich Architects. Design principal Roger Duffy explained how the stations would work with the existing infrastructure around them: “At Fort Lauderdale, we’re looking to link up with a bus service that will connect the cruise port and the station.” The city is also pressing on with plans for a streetcar system called “The Wave” that would connect with the station as well.
Meanwhile, at West Palm Beach, the 60,000-square-foot station is located at the center of downtown and will connect with the existing trolley network as well as Tri-Rail and Amtrak. In Miami, the station inhabits a similar location. A zoning override that turned the area into a special transit district was required to build the station, and tracks here are elevated 50 feet into the air so that the 11,000-foot-long station can bridge roads and pedestrian pathways.
Like any contemporary train terminus, the station will offer a ton of retail space, with room for a food court too. Duffy, however, stressed that the station was “not like duty-free at an airport,” where you have to weave through shops to get anywhere. Amenities will also cater to the area outside the building. Space for food trucks—a hit in Florida—has been provided, while skylights where the station bridges the streets offer daylight.
The Brightline train itself was designed by the LAB at Rockwell Group—an in-house strategy and technology studio at the New York architecture and design studio. The LAB at Rockwell Group worked with All Aboard Florida to conceive the Brightline name, brand platform, visual identity, and designed the train’s interiors as well as the exterior graphics. In addition to this, one of Rockwell Group’s architectural studios designed the interior check-in areas, food and beverage areas, and lounge experiences for all four Brightline stations.
Using the Brightline project as a springboard, Bravo is embarking on a $3.6 billion (remember that number?) transport scheme. Part of “Strategic Miami Area Rapid Transit,” otherwise known as the S.M.A.R.T. plan, 82 miles of track will be laid along six transportation corridors that involve local services, including the suburban Metrorail and the elevated monorail Metromover.
In addition to new tracks, existing tracks are also finding a new lease on life as a haven for pedestrians and cyclists. Known as the “Underline,” the rails-to-trails scheme, comes from James Corner Field Operations (JCFO)—the same firm who developed New York’s hugely popular High Line.
As one might guess, the scheme involves area underneath the Metrorail being turned into a landscaped oasis filled with pedestrian paths, cycle lanes, and native planting. The 10-mile stretch is planned to run from Brickell Station down to Dadeland South Station. Phase one is occurring in Brickell, where work is due for completion in 2019, set to cost netween $7 million and $9 million. “Brickell has grown explosively in the past 10 to 15 years,” said Meg Daly, president of Friends of the Underline, the group leading the project. “We really believe that this trail-cum-park will offer incredible amenities and green spaces to offset the vertical growth and increased density in the area.”
Expanding on this, Isabel Castilla of JCFO listed amenities such as a dog park, an outdoor gym, a basketball court that doubles up as a space for yoga classes and similar activities, as well as a 150-capacity bicycle garage (Miami-Dade’s first) and a bike repair station. Art will also line the trail, and amenities will be site-specific: In the University of Miami area, a beach volleyball court will be installed.
According to Irene Hegedus of the DTPW, providing safe bicycle routes is a high priority. Castilla added that the shade provided by the Metrorail is “critical” for a project where people are encouraged to “walk, run, and cycle to stations and along the path.” “Working with the existing infrastructure,” she continued, “we hope this leads to the rezoning and re-visioning of areas along the Metrorail as transit-orientated development sites and areas where, as Miami continues to grow, it hopefully grows in a denser way near transit stations rather than continuing urban sprawl that is very dependent on highways and cars.”
Bravo, too, is aware of the interwoven relationship between transit development and the densification of urban areas. Another tool she discussed to further assist Hegedus’s and her ambitions was the possibility of Uber and Lyft entering the fray of her transport plans, acting as the “first and last miles” for journeys.
Now operating in Miami (after three years of lobbying for service legalization), Uber and Lyft previously found success in other parts of Florida, notably in Pinellas Park and Altamonte Springs where rides are subsidized and saving the cities considerable money. Altamonte Springs City Manager Frank Martz described the pilot partnership as “going very well,” but said the scheme is due to end in July.
The low-cost nature of services such as Uber and Lyft is a key to their success. Already able to outprice traditional taxi drivers, ridesharing services Uber Pool and Lyft Line are looking to compete with bus service, too. Uber has gone further than mere carpooling by introducing pickup points optimized by algorithms that essentially create Uber bus stops.
Uber is also losing money—approximately $3 billion per year. In December, economist Justin Wolfers commented that “prices will rise once they’ve succeeded at monopolizing the industry.” If he is correct, the governmental embracing of Uber and Lyft long-term will prove to be shortsighted. Evidence of what happens when alternative public transit routes become unavailable can be seen in London. During a tube strike earlier this year, Uber fares surged by 450 percent; one rider was reportedly charged $138 for a five-mile trip.
It should be noted, though, that Altamonte Springs and Pinellas Park went with car sharing due to other circumstances not going their way. The Altamonte Springs city government set aside $500,000 (of which only a fraction has been needed) for private-hire subsidies after it was denied funding for a $1.5 million pilot “FlexBus” program. At Pinellas Park, the program emerged in response to a 2014 referendum in which local voters declined to adopt a one-cent sales tax to aid transit in the area.
In Miami, however, residents appear to be more enthusiastic about public transport. The “People’s Transportation Plan,” a half-penny charter county sales surtax is helping to fund the S.M.A.R.T. project, something the public voted in favor of back in 2002.
All this, too, shouldn’t suggest that Miami is waging all-out war against the automobile. Getting around by car is being made easier by what Bravo calls “smart signals”—traffic signals that adapt to current states of congestion. Using cameras, they monitor intersections and use AI to optimize traffic flow. Miami-Dade County is investing $40 million this year for the implementation of the traffic signals along major corridors, part of a five-year, $160 million effort. Other smart-city services include 300 soon-to-be-installed wi-fi transit hotspots from CIVIQ Smartscapes.
With all the proposed infrastructural plans, varying in scale, Bravo is under no illusions about the difficulty of the task. “This is a huge cultural change,” she said. However, Bravo is optimistic about how future generations will take to the changes. “New millennials are cool about public transportation,” she added. Such unprecedented growth seldom comes around often, and the chance to invest off the back of hefty tax receipts may be fleeting. Miami’s public transit system is dire, but if it continues to ride the wave of public support and enact its plans, change in the form of mobility lies ahead.
- Drexel Square will feature an elliptical lawn and supposedly represent the "continuation of William Penn’s original vision for the city’s 'public room.'" The area will be active during the day and night and is set to "serve as the gateway into University City from Center City and 30th Street Station."
- JFK Boulevard is due to be transformed into a "shared esplanade" linking 30th Street Station with the Armory building. This space will act as an overspill area for commuters and visitors leaving the station, safely integrating pedestrians, bikes, and cars in the same space, "while providing a rich new greenway for the public."
- Market Street, a well-known thoroughfare in Philly, will receive new bicycle and pedestrian lanes, as well as trees that will line the street to counteract noise and pollution.
- The Wintergarden. Renders for the space show an elevated, balustrade-encased area overlooking the streets filled with greenery and families. The surrounding area appears to be laboratories, so it is unclear if this is a specific public space. The Architect's Newspaper (AN) reached out to the developers (Brandywine Realty Trust and Drexel University) for clarification and is waiting to hear back.
