A pedestrian bridge linking the Clinton presidential library in Little Rock with North Little Rock should be completed months after the library opens this fall. Work on the Arkansas River bridge will be done after North Little Rock completes a waterfront plan. North Little Rock city officials are working on a riverfront redevelopment plan similar to Little Rock`s River Market district. The bridge is on old railroad trestle that will be converted into a foot bridge. The 4 million dollar bridge renovation is part of the 160 million dollar Clinton project. Foundation officials had hoped that work on the bridge would be underway by now, but it likely won`t begin until the summer.
