Pennsylvania's got a quick plan for reopening Interstate 95 in Philadelphia, they'll wall in the underpass with tons of recycled glass, then pave over that, so the 95 can be used until a permanent solution is ready

Workers will fill the gap — which is roughly 100 feet long and 150 feet wide — by piling recycled foam glass aggregate into the underpass area, bringing it up to surface level and then paving it over so that three lanes of traffic can reopen each way, Shapiro said.

The company supplying the glass aggregate, AeroAggregates of North America, has a production site just south of Philadelphia along the Delaware River. There, it mills glass bottles and jars diverted from landfills into a powder and heats it into a foam to produce small, lightweight nuggets that are gray and look like rocks — but are as light as Styrofoam, said CEO Archie Filshill.

Each one is about an inch or inch-and-a-half wide.

Filshill estimated that it will take about 100 box-truck loads to haul about 10,000 cubic yards (7,600 cubic meters) of the glass nuggets required for the I-95 project. The total weight is around 2,000 tons, a fraction of the weight of regular sand or dirt, meaning that it will take many fewer trucks to bring it to the site, Filshill said.

PennDOT was the first to use his company's product after he began making it in 2017, and it is now approved for use by 23 state transportation departments around the country
