The traffic from a new north-south road connecting Upper Kedron and The Gap - which will be built as part of a massive new suburb in Brisbane’s western suburbs - could become a major concern for Brisbane City Council.

Mt Nebo Road – the southern edge of where the project is proposed in The Gap – is currently only a single lane road, bounded by forest on one side and D’Aguilar National Park on the other.

Mt Nebo Road connects with Waterworks Road, running through Ashgrove and The Gap.

As revealed on Tuesday by Fairfax Media, Western Australian developer Cedar Wood proposes building 1350 homes over 10 years on the 227 hectare block between The Gap and Upper Kedron, with entrances from Mt Nebo Road.
