The next leg of that circuit to be opened will be the paved trail between the Old Chain of Rocks Bridge and Alton, so that bikers can ride from the Arch all the way to Pere Marquette State Park starting in August. The only nontrail part of that ride will be the three-quarters-of-a-mile stretch by the Chain of Rocks water plant, where bicyclists will have to ride on pothole-riddled Riverview Drive, sharing the road with trucks and cars -- and within spittin' distance of the water plant's fence.
