In recent years, there has been concern that the original plan of a wide, multi-sectioned, multi-laned, tree-lined boulevard, while beautiful to travel on, is not very engaging for pedestrian or other public use. Traffic along the Parkway has decreased considerably because of the completion of Interstate 676 (Vine Street Expressway), linking the Schuylkill Expressway with the Benjamin Franklin Bridge. In response, the roadway has been narrowed somewhat and the sidewalks expanded around Logan Circle. Various plans for the rest of the Parkway, some of which would insert shops and other smaller structures into the long stretches between museums, have been proposed, but none so far have been thought feasible or financially sound.
