There are four aims of the proposed bridge: to reduce traffic incidents on Whylandra Street, increase connectivity between the central business district and west Dubbo, reduce travel times on the road network and to cater for city growth.

The proposal is currently on public exhibition.

Director infrastructure Julian Geddes said council's Transportation Strategy had identified the need for an additional low-level crossing of the Macquarie River to reduce traffic congestion, primarily on Cobra Street and the LH Ford Bridge.

"Traffic studies indicate that this bridge will be required within the next five years or existing networks will be under traffic stress, and Dubbo will not be able to maintain its '10 minute city' reputation," he said.

"A third river crossing for Dubbo has been strategically identified, for many years."

There are currently two route options on exhibition for the bridge.

The proposed bridge could be constructed from Minore Road to Sandy Beach Road/Bligh Street or from Minore Road to South Street/Bligh Street. It's believed the bridge could cost between $33.9 million and $35.7 million, depending on which option is chosen.

In July, it was determined only the two options would be placed on exhibition, despite not all councillors agreeing to the idea.

The feedback period on the proposed South Dubbo Bridge and the Transportation Strategy will be open until February 5.

"Council will use the initial round of feedback to gain a better understanding of the community's views of these strategic alignments, and their potential impacts on stakeholders and user groups," Mr Geddes said.

"Staff will then progress with a business case that details an assessment of benefits and costs, as well as the community feedback, and present this to Council for further consideration.

"This will not be the only opportunity for the community to provide input into this project, as it progresses."

The plan can be seen and feedback given via the Dubbo Regional Council website.

A community consultation session will be held on November 25 at the Dubbo Regional Theatre and Convention Centre. Registration is required.
