how to obtain elevation points for a road using contour?

Question

I have contour lines, & roads centerlines feature classes, I need to get points with elevation in the starts, intersections, & the ends of the roads, how can I get this information? I used the "Intersect" approximity analysis tool, but I think it is not accurate enough. is there a way in 3D analyst or Spatial analyst? Thanks

Several ways to skin the cat, but I don't know if you want ArcGIS (what extensions do you have?) or an Open Source solution.

For ArcGIS, one way is to create a DEM from your contours, and assign Zs to the vertexes.
