The SR 509 Completion Project in the SeaTac/Des Moines, WA area includes a new Veteran's Drive tunnel under I-5. The tunnel will create a link between the southbound off-ramp (on the right) to Military Road (visible in the photo's upper left).
The tunnel will use steel arches, but there's still a lot of concrete to be poured. In this photo, a concrete pumper truck pours concrete for some of many walls.
The SR 509 Completion project is part of the Puget Sound Gateway program which completes critical missing links in Washington state's highway and freight network.
