Transport for NSW is calling for community feedback on its plan to upgrade The Driftway between Londonderry Road at Londonderry and Blacktown Road at South Windsor.
The proposed works are part of Stage 1 of the New Richmond Bridge and traffic improvements project.
Transport for NSW says upgrades to The Driftway would support the future bridge and offer safety benefits for the community.
The work would include upgrading The Driftway intersections at Londonderry and Blacktown roads to new roundabouts, improvements to The Driftway intersections with Luxford and Reynolds roads to include right turn bays, road widening and drainage improvements.
Online communuty sessions about the proposal will be held on November 24 and 25 and the plans can be viewed on the project web page. The public display period will close on Friday, December 10.
Feedback will be considered in a submissions report to determine the proposal.
For more information about the community sessions or to submit feedback, visit nswroads.work/richmond-bridge or call 1300 370 778.
Earlier this year Transport for NSW consulted on its preferred option for the New Richmond Bridge and associated traffic improvements.
It is currently considering the the feedback and will complete further investigations before adopting a design that "delivers the greatest community benefits within the project's allocated funding budget".
Liberal Senator Marise Payne said that once complete, the third river crossing would save motorists time in peak hours between Richmond and North Richmond.
"We have listened to the Hawkesbury community and delivered half a billion dollars to help address this well-known bottleneck," she said.
Hawkesbury MP Robyn Preston said that the existing Richmond Bridge carried around 31,000 vehicles per day in each direction.
"This creates significant traffic congestion between the Richmond and North Richmond townships, so it is important we make preparations for the new bridge now and encourage feedback on upgrades to The Driftway," she said.
"Upgrades to The Driftway were common to all options considered for the New Richmond Bridge and that work is being progressed as Stage 1 of the project.
"With the area growing in population, it is imperative we complete these important works to improve safety and meet the needs of the community."
