Best practices for centreline/crown shift on divided highways

Description

Over a number of years the department has developed some practices to address the need for thicker pavement structures and wider shoulders on the right hand side (looking in the direction of travel) on divided highways. These practices improve cost-effectiveness by allowing thinner pavements to be placed on the left lane of the twinned highway and/or deferring the need for grade-widening by allowing the right shoulder width to be increased through reduction of the left shoulder width. Both of these practices are achieved by shifting the physical crown line and/or allowing the painted centreline to be offset from the physical crown line.
