From Viaduct to Boulevard

Delft did something remarkable with one of its biggest urban barriers. Instead of merely replacing an aging railway viaduct, the city buried the tracks and used the reclaimed corridor to reconnect neighborhoods, create public spaces, and build an entirely new piece of the center. The walk begins beside a working windmill that survived extraordinary engineering, then follows Phoenixstraat along the viaduct’s vanished path. Historic and contemporary stations reveal changing ideas about railway architecture, while the map-lined concourse of Station Delft makes the modern transport hub feel rooted in the old city. Farther south, Nieuwe Gracht and Van Leeuwenhoekpark transform former railway land into water, greenery, housing, and inviting walking routes. At the tunnel portal, trains return dramatically to daylight before the route reaches the solar-powered Delft Campus station. This tour is ideal for architecture enthusiasts, railway fans, urbanists, and anyone curious about how cities repair old divisions. It offers a compelling lesson in Dutch planning: infrastructure can carry more people while also making the streets above quieter, greener, and more human.
