Spc. Frye was killed Feb. 16, 2004, while serving during Operation Iraqi Freedom.
While the bridge over Kelly Brook was named for her, the marker was off the highway, in a spot motorists couldn't see it. After a push from the family and legislators, another sign was added this week.
The DOT had concerns about having too many signs and it being distracting, but says that this sign is an appropriate way to honor Frye.
