Two meetings will be held next week for local residents to have their say on proposed routes for the duplication of the bridge at North Richmond.
Community information sessions will be held at North Richmond Community Centre and Richmond Community Services on December 4 and 7 respectively, giving locals a chance to speak with the project team, provide feedback and learn more about the proposal.
Feedback on the potential routes is invited until Friday, December 20 and will be considered when determining a preferred route, a Transport for NSW statement said.
Transport for NSW Executive Director Sydney, John Hardwick, said the federal and state governments had allocated $250 million for the project.
"Richmond Bridge is the only Hawkesbury River crossing currently serving Richmond, North Richmond and many other townships, so it is essential work continues to support the growing community," Mr Hardwick said in a statement.
"The existing bridge carries up to 31,000 vehicles each day so it is important to ensure motorists are provided with improved journeys as the region grows.
"Earlier this year, Transport for NSW established a Community Working Group which has assisted in identifying these potential routes for further investigation, based on the needs of the local community.
"The community is now invited to have their say and provide vital feedback as work continues to investigate potential routes."
More than 65,000 people already lived in the Hawkesbury region and numbers were expected to grow as the region continues to develop, he said.
"Intersection upgrades have already been completed at the intersections of Kurrajong and Old Kurrajong roads as well as Bells Line of Road, Grose Vale and Terrace roads to help reduce congestion for motorists," Mr Hardwick said.
"Investigations are now being carried out to prepare for the March and Bosworth streets intersection upgrade which will further improve journeys.
"Transport for NSW will continue to work closely with the community and a range of key stakeholders as plans progress for the proposed duplication of Richmond Bridge."
