Hi Ed- Have you tried using multiple Directions objects?
Here's an example where I process a series of results in javascript and calculate the directions for each, using a different directions object each time: http://gmaps-samples.googlecode.com/svn/trunk/googlebar/googlebar_directions.html Let me know if there are problems with that technique. - pamela On Tue, Oct 7, 2008 at 4:45 PM, Ed Syrett <[EMAIL PROTECTED]> wrote: > > I need to show multiple routes on a map.
