MAP TYPE SIGNS FOR ROUNDABOUTS AT GRADE SEPARATED JUNCTIONS
5.45 Figure 5-22 shows the basic design of the route symbol when approaching from the side road. All route arms and stubs have a thickness appropriate to the route indicated. The design can be adjusted to suit the circumstances, such as indicating an additional exit from the roundabout. The oval roundabout and side arms can be rotated, as shown in figure 5-23, if this best illustrates the true layout of the junction.
5.46 Figure 5-24 shows the basic design of the route symbol when approaching from the exit slip road of either a motorway or an all-purpose road. The approach arm and stubs opposite are always 5sw wide regardless of the status of the route (this is consistent with the map type advance direction signs on the main carriageway which also have a width of 5sw - see para [#5.28|5.28]]). The side arms have a width appropriate to the status of the route indicated. It is possible to adjust the design to suit the circumstances; an example is shown in figure 5-25. Some grade separated junctions on three levels have slip roads on two major routes, with an interconnecting roundabout. The design of the roundabout symbol is shown in figure 5-26.
