This geocache is an easy park and grab on the Murray Farm Road Bridge, which was rebuilt with the construction of the M2 and opened in 1997.
This geocache is NOT on the M2! Access from Murray Farm Road/Castle Howard Drive, please park at the waypoint and walk to GZ. You do not need to climb over the railing, it is accessible from the footpath.
