Work on the $342 million Nowra Bridge project will soon begin with the design and construct contract awarded to Fulton Hogan Construction.
Deputy Prime Minister and Minister for Infrastructure, Transport and Regional Development Michael McCormack said the project, funded by the Federal and NSW Liberal and Nationals governments, would improve traffic flow and ease congestion on this major section of the Princes Highway.
"We are keeping communities connected and delivering faster and more reliable journeys for those travelling the South Coast," Mr McCormack said.
"The new Nowra Bridge will build upon road upgrades currently underway in the region and will better cater for heavy and over-height vehicles."
He said the project was part of the Federal Liberal and Nationals Government's record $100 billion pipeline of infrastructure projects getting people to where they need to be sooner and safer.
Minister for Regional Transport and Roads Paul Toole said the new four-lane bridge over the Shoalhaven River would improve traffic flow on the Princes Highway and deliver faster and more reliable journeys in the Nowra and Bomaderry area.
"We are building the infrastructure projects needed to support growing areas such as Nowra, which is why, since 2011, the Commonwealth and NSW governments have invested more than $2.5 billion to upgrade the Princes Highway to create safer and more efficient journeys along the south coast of NSW," Mr Toole said.
"About 50,000 motorists already cross the Shoalhaven River every day and with traffic only set to grow, this project will ensure safer and more reliable journeys now and for the future."
South Coast MP Shelley Hancock said the Nowra Bridge project would change the way motorists move in and around the region.
"As part of the project, we will upgrade the intersections at Illaroo Road, Bolong Road and Bridge Road and will build a new local road linking Lyrebird Drive with the Princes Highway south of the current Pleasant Way intersection," Ms Hancock said.
"During early planning it became clear a new bridge could address key issues in the area including maintenance difficulties with the old bridge."
Kiama MP Gareth Ward said the new bridge would see the Princes Highway upgrade continue down the coast.
The existing southbound bridge will be retained for ongoing community use, such as pedestrian and cycle path access.
Early work such as utility relocation and demolition of acquired properties will start in the coming weeks with major work set to start later this year.
The project is scheduled to be completed by mid-2024, weather permitting.
The community will be kept up to date as construction on the bridge draws closer.
