The city is sponsoring a $30 million proposal to make the crossing between the Portland neighborhood and New Albany, Ind., a “shared-use path” that would open by 2040. 

The CSX railroad bridge on Third Street has snared too-tall vehicles for years. Kentucky officials are banking on new technology to curb crashes there.  

Officials view the crossing as the ideal western link in a 13-mile trail that would connect both sides of the river, complementing a larger 100-mile Louisville Loop stretching across parks and neighborhoods in Jefferson County.
