Engineers Con Boutsikakis and Andrew Paterson join us on our building roads podcast. Con and Andrew explain how roads are built on embankments using natural resources, how orads are designed to speed limits and the type of planning involved.  The engineers explain different tunnelling techniques for train and road tunnels.  Ross owns a road according to the government and asks questions to improve his own road.  We compare public transport v road network in Sydney and Halil wants to become a mayor by way of a democratic dictatorship!!!
