We’ve been asked a few times what this does and it’s easiest to explain with a diagram (see the incredibly professional drawing below). It allows traffic to go from Manville Road to the southern half of Elmbourne Road both ways (see orange arrow) and also allows traffic to go from Dr Johnson Avenue/Hillbury Road to the northern half of Elmbourne Road both ways (see purple arrow). The diverter is placed diagonally across the junction (see green line). There is a small space large enough for bicycles on either side of the diverter so that cyclists can go round it.
