From 1917 to 1949, the Harahan Bridge was open to car traffic, but today the old bridge only carries rail traffic.
But that may change with a plan to convert the old 1917 motorway into a bicycle and pedestrian path across the river. Union Pacific owns the rail bridge, but in February of last year, they agreed to allow the walkway conversion. The city of Memphis and the city of West Memphis, Arkansas support the project.
On Monday night (March 12th), the Downtown Memphis Commission is sponsoring a public meeting on the project at the Memphis College of Art's downtown campus (477 S. Main) at 5:30 p.m. They'll be discussing a timeline for the project and gathering public input.
To see an animation of what the pedestrian path might look like, check out the Harahan Bridge Project website.
