Thanks Ted.
Yes you can still drive across the steel bridge. To get there you have to take the exit off of Highway 101 to Highway 1 toward Lompoc. Just as you head toward Lompoc you make a left turn which takes you back in front of the Vista de Las Cruces school. This road dead ends at the old bridge.
To get to the other side of Las Cruces you go the other way off of the 101 exit which is just a quick access road along the freeway. There is nothing left but a trail to the mineral hot springs that is behind where the old garage use to sit.
I am working on a geocaching tour of Highway 101 in this area for those of you that know what that is. For those that don't, we will be hiding old pictures of historic places along Highway 101 and posting the GPS coordinates on a website so that people can locate them and see what the old service towns looked like in the actual location where they once sat.
