Bicycle Beta at Google Maps
Yesterday, Google Maps added a beta for Biking Directions. You can get the full skinny from the Google Blog
or go right to the Google Maps Page and choose “Bicycling” from the drop down menu under Get Directions.
Google added information about bike trails, lanes and recommended roads directly onto the map. When you’re zoomed into a city, click on the “More” button at the top of the map to turn on the “Bicycling” layer. You’ll see three types of lines appear on the map:
Dark green indicates a dedicated bike-only trail;
Light green indicates a dedicated bike lane along a road;
Dashed green indicates roads that are designated as preferred for bicycling, but without dedicated lanes
I tried it out and it worked very well. Of course remember as the warning says when you submit your destinations:
