According to Active Transportation Alliance, the 18-mile Chicago lakefront path is the busiest trail in the country, with peak usage at more than 30,000 users per day during the summer. (Lucky me) it is also the main artery of my commute to work most days. Even the most occasional user can tell you - it is simply not engineered/able to accommodate such a large volume of mixed mode users all travelling at different speeds.
ATA is campaigning to support increased investment in separating pedestrians and bicyclists on the trail and other safety improvements.
Everyone should enjoy the lakefront. Often. It is one of the City's great assets. Improving park facilities like trail improvements will only enhance the experience for us all.
