β»οΈ Tire waste built highway in San Francisco
Engineers used 662,700 shredded waste tires to build an on-ramp under unstable bay mud. This solution was implemented at the intersection of I-880 and Dixon Landing Road in Milpitas. The tire aggregate reduced downward pressure by 40% and saved $477,000 in 2000. This innovative method solved a foundation nightmare and diverted toxic waste streams. After 22 years, the structure has shown no signs of structural repairs or issues. π€―
