A collection of resources exploring the physical design of freeway and highway infrastructure — from the shapes of interchanges to the cinderblock patterns on freeway sound walls. It’s about the way freeways look, the way they appear (or don’t) to the driver and passenger, how they use the land, and how their concrete forms have been sculpted and grafted onto the landscape.
How roadside noise barriers are designed to absorb sound and evade attention
The freeway sound wall may be as overlooked as it is ubiquitous. Lining interstates and highways and freeways across the United States, these concrete and cinderblock structures are a blur in the peripheral vision of our automotive world.
This is partially by design: sound walls serve the utilitarian role of blocking and containing the tremendous noise generated by high speed transportation, and they’re built to do their job without distracting the people driving past in thousand-pound vehicles at more than 100 feet per second.
