Picture of Chattanooga, TN - This is a picture of Chattanooga, the closest city to me. There are 4 bridges that cross the Chattanooga River in downtown...three are driving bridges and one is only a walking bridge. The bridges in this picture are of the Walnut Street Bridge and the Market Street Bridge. The Market Street bridge is the blue one and the Walnut Street Bridge is just a walking bridge. The 'Walking Bridge' as it is commonly known is the 2nd largest walking bridge in the nation. The walk across the river is a wonderful walk. One one end is a wonderful shopping area with a newly rennovated park and on the other side is Chattanooga's art district with museaums and great restaurants.
