Paul,

Go to this bing site to see the t-6 crossing. Some how Google Earth was removed from my computer. I'm researching this and will put that program back on here as it is better than bing maps. Because bing maps does not show GPS cordinates.
While this map does not show the bridge you can follow hook creek to hwy. 18 , where I hiked to once. It is all up hill from those springs.
Glad to help !
