History

Imagine riding your bike along an ordinary neighborhood street. Cars are still there, but there are far fewer of them now, and they drive slowly—as if they understand this isn’t their place. Bright green bike symbols are painted on the asphalt, special signs stand at intersections, and short posts in the middle of the road make it harder for cars to cut through. You feel safe. This is exactly what “Neighborhood Greenways” look like in Seattle, a city on the shores of the Pacific Ocean. And the most surprising part is this: to create a street like that, they didn’t have to build a single new road.

What Is a “Green Street,” and How Does It Look?

City planners in Seattle wrestled with one big question for a long time: how can we make it safer for cyclists to ride without spending billions of dollars building brand-new special bike routes? The answer was unexpectedly simple: take quiet residential streets that already exist and slightly change the rules for how people use them.

That’s how “Neighborhood Greenways” appeared—“neighborhood green streets.” These are regular residential roads where cyclists and pedestrians are given priority over cars. Cars can still drive on these streets, but only slowly, carefully, and not as a shortcut between big avenues.

To make this happen, designers used several clever tricks. Bright drawings appeared on the road—bikes, arrows, and special signs. At intersections, they installed “diverters”: small barriers that stop cars from driving straight through, but are easy for cyclists to pass around. They added speed bumps and special signs with green leaves. The street may look the same, but it feels completely different.

The first such routes in Seattle showed up around 2012–2013, and since then the network of green streets has grown across the city—connecting neighborhoods to parks, schools, and public transit stops.

The Netherlands Inspired the Idea: A “Woonerf” Where People Live

Where did the idea come from? Surprisingly, from a small country on the other side of the world—the Netherlands. Back in the 1960s, Dutch cities were crowded with cars. People complained: children can’t play outside, older residents are afraid to step out of their homes, and cyclists risk their safety at every intersection. Then city planners came up with a concept they called “woonerf,” which in Dutch roughly means “a yard where people live.”

The idea was simple: make it so cars can’t go fast—almost physically. The road was “broken up” with curves, benches and trees were placed right in the roadway, and bright patterns were painted on the asphalt. Cars turned into guests in someone else’s space, not the owners of the street.

This idea spread across Europe and then around the world. American city planners studied the Dutch experience and wondered how to adapt it to their own cities. Seattle was one of the first U.S. cities to try something like this on a large scale.

It’s also interesting that Seattle is a very hilly city. Here there are streets with such steep climbs that even pedestrians get tired. That’s why planners chose gentler routes for the green streets—roads that you can actually ride on comfortably on a bike.
