[4] Each level of government, federal, state, and city, preserved its right of way and established speed limits across the Kentucky and Indiana Bridge.The city of Louisville[5] and Federal Government also declared the K&I Bridge a postal route and retained its right of way in perpetuity.[8] On both the Louisville and New Albany sides, the common roadway and railway tracks are grade separated or completely independent.The bridge at Louisville is to have a railroad track, a passageway for the vehicles, streetcars, and a walk-way for foot passengers.The K&I Bridge Board of Directors reported, "The common roadway has been operated with remarkable freedom from accidents."[10] Upon opening, the bridge company also offered the Daisy Line, an early steam locomotive commuter train service.The new bridge was double tracked to handle increasingly heavier train and now automobile traffic, eventually receiving the U.S. 31W designation.[12] The bridge also featured a rotating swing span opening for the passage of ships in high water.On February 1, 1979, an overweight dump truck caused a small segment of the steel grate roadway on the bridge to sag about 1 foot (0.30 m).[14] Proposals to turn the roadway lanes into pedestrian-only usage have also been rebuffed by Norfolk Southern, citing liability concerns.
