Down in Memphis, they put a beautiful bike/ped crossing on an active railroad bridge... www.memphistravel.com/BigRiverCrossing

In February 2011, Union Pacific Railroad officials agreed to the idea of converting the 1917 roadways into a bicycle-pedestrian walkway across the river. In June 2012, Memphis was awarded a $14.9 million federal grant to build the walkway. The overall project was expected to cost $30 million, of which about $11 million was used for the Harahan Bridge portion. Construction was completed in 2016.

It is a cantilevered through truss bridge that carries two rail lines and a pedestrian bridge across the Mississippi River between West Memphis, Arkansas and Memphis, Tennessee. The bridge is owned and operated by Union Pacific Railroad. It was built with roadways cantilevered off the sides of the main structure for vehicles. These roadways are owned by the cities of Memphis, Tennessee and Crittenden County, Arkansas, and were used from 1917-1949, until the Memphis & Arkansas Bridge opened 400 feet south of the Harahan.

Why can we do that here?

Investigation of fire on K&I bridge bears watching as it may (oddly enough) present opportunity for opening the bridge to pedestrians. Several local fire depts worked together to put out the fire. Norfolk Southern Railroad might be inclined to a degree of appreciation. The city of Louisville still has to raise the bidding by investing in the west RiverWalk.
