Vehicles are restricted to this side road during wet weather conditions and are not permitted to travel along the baseline. Vehicles should maintain 5m clearance to pillars at all times.
Vehicles must give way to all pedestrians when crossing footpath between Pillar 4 and Pillar 5.
The pillars are locked and also require bolts to attach the tribrachs. Contact the Townsville Department of Resources business centre for baseline bookings and to arrange collection of bolts and keys.
