Legislative Assembly for the ACT: 2009 Week 13 Hansard (Thursday, 12 November 2009) . . Page.. 4918 ..
The road alignment and intersection with Horse Park Drive was determined by two planning feasibility and forward design studies. Since late 2003, the Territory Plan map has shown the current alignment of Well Station Drive Extension including the location of its intersection with Horse Park Drive. This is well prior to the sale of the adjacent blocks and house construction.
An alignment to have Well Station Drive intersect with Horse Park Drive further to the east has been considered. However, it has been discounted as a viable option due to the significant constraints caused by the proximity of Sullivans Creek.
These constraints include:
Sullivans Creek passes under Horse Park Drive on the same alignment that the alternative approach road would have to take. Constructing a road on the same alignment as the creek is not possible.
Constructing the road on either side of Sullivans Creek is also not feasible as the formation next to the creek is not suitable for road construction.
Water levels from Sullivans Creek during flood periods would inundate the road unless it was constructed at a high level. This would involve additional and significant costs to construction.
The other factors relating to the chosen intersection location of Well Station Drive and Horse Park Drive are as follows:
The current intersection location will align with the proposed collector road into Throsby.
Moving the collector road into Throsby further to the east to align with the alternative intersection location would place the road close to Goorooyaroo Nature Reserve. This is likely to have environmental impacts and reduce the overall effectiveness of the collector road.
The alternative of having two ‘T’ intersections in close proximity along Horse Park Drive in a staggered ‘T’ formation is not desirable either as once the suburbs are fully developed they will be signalised and the subsequent that if she needs to take time out to inspect rental accommodation next week inconvenience to motorists would defeat the purpose of the Horse Park Dive arterial road.
The alignment of Well Station Drive and the intersection with Horse Park Drive has been investigated thoroughly. The current arrangement provides the most cost effective delivery for the road infrastructure and is considered to provide the best outcome to the residents of Gungahlin as a whole.
