In 2024, Arizona used foam made from 100% recycled glass at 19 sites while widening 23 miles of I-17; the lightweight fill helped culverts built for two lanes support added lanes
- I-17 Improvement Project using foam glass aggregate as a new innovative construction materialEngineers in Arizona have used an unusual material to expand a major interstate: tens of thousands of tonnes of crushed recycled glass.
- During the expansion of Interstate 17 north of Phoenix, construction crews used ultra-lightweight foam glass aggregate at 19 locations along a 23-mile section.
- The material, made entirely from recycled glass, provided a lightweight structural fill that allowed existing drainage culverts, built decades ago for a two-lane highway, to support extra traffic lanes without b
