Old Chain Of Rocks Bridge - Flashback Friday

Posted this week in 2015 (3/26 <--> 4/1).  This one is from my 365project. 

Old Chain Of Rocks Bridge

Opened in 1929, this bridge carried historic Route 66 across the Mississippi River (just north of St.Louis). Closed in 1970, the bridge was repurposed in the late 1990s for walking and biking.
