Molonglo 3 East has been give an optimistic timeline for completion by 2041. The future is wildly uncertain. Projects run routinely longer than planned. This is generally true but certainly true for the ACT Government. We have good intent, but building things is complicated. Environmental approvals can add years to the process and are unpredictable. Recent information on the environmental approval process for the Deep Creek Pond in Whitlam sheds light on this.
Molonglo 3 East is in an early stage of planning and the significance easily missed driving by. In the Planning Design Framework the ACT Government outlines what it does and does not want, however, the intention is to leave plenty of space for good urban planning.
The Molonglo Valley is not flat and that is well known but it does cause problems. In Molonglo 3, on the north of the river, the gradients can be a challenge.
