Memphis Bridge Sport Route

I remember the late Michael Feehan telling me about a bolted climb on the base of one of the Mississippi River bridge supports. Maybe 5.11b? Anyone know anything about this?

Back in '93 I used to climb with the Memphis mountaineers on the bridge supports. They had a system set up that we could pull a cord to take your rope up through an anchor. I doubt it is still there. the routes were around .10, but I bet you could make an .11 easily. Never saw a bolted route. Unfortunately my lasting memory is hearing ricochets coming off the support as someone was shooting from the Arkansas side! I yelled for my belayer to dirt me and I never went back. poison ivy was pretty bad too. Be careful out there.
