Putnam Drive is a misnomer. This path, labeled "Putnam Drive" provides access to an outdoor ecology lab owned by the University of Wisconsin Eau Claire. It also serves as a student walkway, providing four stairways to State Street. (There is no evidence on State Street that there is a bridge here, except for the black, pipe railings that can be seen above the portal.) The "Tunnel" is actually a large, steel culvert.
