Most infrastructure stories focus on the cost of construction or the inconvenience of detours. This piece flips the script entirely, arguing that closing a major bridge to cars for four months didn't break the city—it revealed how much better the city functions when cars are removed. Jason Slaughter doesn't just document a renovation; he uses the temporary closure of the Bera Bridge in Amsterdam as a live laboratory to prove that noise, congestion, and danger are not inevitable byproducts of urban life, but design choices.
The Myth of the "Bike-Friendly" Past
Slaughter begins by dismantling a persistent excuse used by urban planners in car-centric cities: that Amsterdam works for cyclists only because it was built before the automobile. He points out that the Bera Bridge and its surrounding neighborhoods were constructed in the 1920s and 30s, well after the Model T became common. "If you take the release of the Model T in 1908 as the date that cars became common then this is the only part of Amsterdam that existed at that time and this is everything constructed afterwards," Slaughter writes. This is a crucial distinction that reframes the conversation from historical accident to intentional policy.
The author's framing is effective because it shifts the burden of proof. It forces the reader to acknowledge that modern Dutch cities were built with cars in mind, yet chose to prioritize people anyway. "Heck about half the city was built after the 196s which makes this even more ridiculous but the people that make lame excuses for bad City design don't know what they're talking about anyway," he adds. This blunt assessment cuts through the nostalgia often attached to European urbanism. Critics might argue that the sheer density of Amsterdam makes it a unique case that doesn't translate to sprawling American cities, but Slaughter's point stands: the design philosophy, not the density, is the transferable lesson.
Cities aren't loud. Cars are loud.
Designing for Flow, Not Just Speed
The commentary moves from history to the specific mechanics of the renovation. Slaughter highlights the stark contrast between the original design of the adjacent Freedom Avenue and the car-centric modifications made in the 1960s. He notes that the avenue was originally a beautiful boulevard that was later "destroyed even more to make it carf friendly which I guess is fitting for an Avenue named after an American." This observation serves as a sharp critique of mid-century urban planning that prioritized throughput over livability.
During the closure, the temporary bridge forced a re-evaluation of how space is allocated. With cars removed, the junctions became significantly more efficient for everyone else. Slaughter observes that "without cars you don't need traffic lights" and that the removal of vehicle queues allowed cyclists to take the most direct path. The result was a junction that felt "so much more civilized" because the artificial bottlenecks created by traffic signals were gone. This evidence supports the broader argument that traffic lights are often a symptom of poor road design rather than a necessary safety feature.
The renovation also introduced specific Dutch design innovations, such as the "banana" island and the "freak cone" (a tapered bike lane). Slaughter explains that "the bicycle path is wider at the start than at the end like the shape of a freak cone. This allows more people to queue up to wait and when the light goes green people cycling can easily negotiate who goes first." This is a masterclass in flow engineering, treating cyclists as a fluid rather than a series of individual vehicles. Transportation engineers in other countries should indeed take note, as this approach maximizes throughput without increasing speed or danger.
The Reality of Disruption
Slaughter is careful not to romanticize the construction process. He acknowledges the logistical headaches, particularly regarding public transit and mopeds. While the temporary bridge accommodated walkers and cyclists, it was too narrow for mopeds, which were banned from the path and enforced by "license plate cameras." He notes, "almost every moped Rider I saw was walking their vehicle." This detail is vital; it shows that the city was willing to enforce difficult rules to maintain safety, a level of political will often missing elsewhere.
Furthermore, the project revealed the inefficiencies of the permanent structure itself. Even after the renovation, a flaw remains where "a single car turning left can block a public transit vehicle with dozens of people on it." Slaughter admits this is a "ridiculous situation," noting that the shared lane design on the bridge itself is a compromise that still prioritizes cars over the flow of mass transit. This is a fair counterpoint to the otherwise glowing review: even in Amsterdam, the legacy of car-centric design is not fully erased, and the bridge still suffers from a "shared lane" that creates potential bottlenecks.
Designing for bicycles is very different from designing for cars.
Bottom Line
The strongest part of Slaughter's argument is the empirical proof provided by the four-month closure: the city did not collapse, and in many ways, it functioned more smoothly without cars. The piece's biggest vulnerability is its reliance on a specific cultural context where cycling is already the norm, which may make the lessons harder to apply in cities where car dependency is deeply entrenched. However, the core takeaway remains undeniable: when you stop designing for the car, the city stops feeling like a machine built for it.
