Rather than treating the old bridge material solely as construction debris, Virginia's transportation authorities and marine-resource officials are using it to expand an artificial reef programme that has been operating for decades.From bridge rubble to underwater habitatThe Hampton Roads Bridge-Tunnel connects the Hampton and Norfolk areas of Virginia. Its expansion involves constructing two new tunnels and trestle bridges to double the number of driving lanes. Making room for the new infrastructure also requires the remov...
