From GZ you can see the concrete pillers which once suported the Polmadie Bridge
The Polmadie Bridge was a footbridge that crossed the River Clyde between Glasgow Green (the Flesher's Haugh area which is largely football pitches) and Oatlands at the west side of Richmond Park. Constructed in 1954–1955, it was made from prestressed concrete. It was permanently closed by Glasgow City Council on 14 May 2015, for reasons of public safety.
Press Reports dated 16 July 2015 indicate the bridge was to be demolished - leaving concrete piers, and allowing restrictions on the stretch of river to be removed.
Work to remove the bridge deck, leaving the concrete piers in place, was began on 12 October 2015. Restrictions on river users were lifted when it was complete.
The Cache is located on the foot bridge over the Polmadie Burn
