A major road that's in my area (Avoca Dr) really needs an upgrade. The first half of the road is a four-lane dual-carriageway and the other half is just a two-lane, single carriageway.
There's a lot of traffic that doesn't really flow between the Davistown Rd roundabout and the Empire Bay Rd roundabout. The road grade is just 2 lane single-carriageway, (minus the 3 lane dual-carriageway in Main town Kincumber).
Here is a couple of drawings of what they should do.
Maybe a nice B route marker might be gazetted :)
