The green mesh in this July 2015 photo is the epoxy-coated rebar of the future southbound State Route 99 roadway at the entrance to the bored tunnel in Seattle. Later, crews will pour the concrete for this section of the roadway, which will tie into completed sections of the roadway inside the bored tunnel.
