Thunder Ave Bridge / Knox CR 389


South Fabius River CR 389 Bridge

View to the southwest

BH Photo #207962



Road is now named Thunder Avenue although it is a bit rough and low traveled. But it's worth your drive. Nice access to the river, you can fish or wade around in the solid rock bottom or take photos of the bridge as I did. UPDATE, Lost to June 2015 Flooding on South Fabius River. Wreckage remains are on north side of CR389. Is easily accessed from north side but the road is rough coming from that direction; The drive from the south is shorter but to access the north bank it requires climbing down a steep bank downstream from original approach. The river is very shallow downstream, bring your boots.

Thanx Chris Gonnerman for the wreckage pics; I hope to get some myself very soon, since my in-laws live close by. I have a friend who works for an engineering firm and he says a replacement is planned.
