While some are thousands of feet higher than others, each state has a highest paved road. This fun list displays bike climbs on all the highest roads in the US, one in each state (that has climbs).
This page provides a comprehensive summary of some of the most epic road bike climbs in the United States. These can be viewed on this page via the map (zoom in to view climbs in particular areas), by Climb Cards (photo and stats), or by a detailed list that can be arranged in metric or imperial units by difficulty, distance (longest climbs in the area), altitude gained, highest elevation (highest summit), average grade (sort by varying distances), lowest start point, etc. Visit the Climb Page to see details and photos for that particular bike climb.
