Treatment of overhead structures – objects thrown or dropped

The Treatment of overhead structures - objects thrown or dropped technical guideline supports the implementation of Engineering Policy EP177 Managing the risk of objects thrown from overpass structures onto roads.
It provides technical guidance to assist in the assessment and management of the road infrastructure features that may contribute to the risk.
Implementing EP177 for state-controlled roads in Queensland in accordance with these technical guidelines will supplement actions taken by other agencies (such as law enforcement) to effectively manage this risk and improve safety for road users.
