Website showing elevations and grades?
Is there a website that one can enter their travel route on and be advised of road elevations and grades? Thanks

Google maps suggests routes between places, and lets you modify them. With terrain mode on, it shows topography, including contour lines when zoom in enough. Grade though has to be calculated by asking for the 'route' between two contour lines, and dividing the elevation difference by the distance.
For example on this map
Washington Pass, WA20
the road climbs 1000 ft in 3.3 miles
grade is 1000ft/(3.3 miles * 5280 ft/mile) = 5.7% grade
Most western state DOT web sites list major passes and have pass elevations. Some also give the maximum grade.
