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).
To build the tunnel, crews are excavating from the middle of I-5, working on the west half of the tunnel first.
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.
