While it's almost three kilometres shorter than the Berry bypass, the Albion Park Rail bypass project will feature more bridges.
Thirteen of them, in fact, across its 9.8-kilometre length - that's one more than on the 12.5-kilometre Berry bypass.
And also part of the reason the Albion Park Rail bypass price tag is $50 million higher than the Berry project.
The fact that the Albion Park Rail bypass runs through land prone to flooding is largely why there are so many bridges.
Without them, the bypass would close just like the Illawarra Highway does in heavy rains.
"Thirteen bridges are being installed as part of the project including five waterway crossings, one access crossing, one railway crossing, three road crossings, and three bridges for ramp crossings," a Roads and Maritime Services spokeswoman said.
"The bridges being installed as part of the Albion Park Rail bypass will reduce traffic delays and congestion as well as improve road safety, highway accessibility and freight efficiency.
"These bridges will also help to improve the flood immunity of the highway."
Ten of the bridges are along the bypass corridor itself, allowing the four lanes of traffic to cross over roads, rail and rivers.
Two bridges will be built to allow roads, including Croome Road, to pass over the bypass.
One bridge will also be built to allow the on and off ramps to cross over one another in the vicinity of the Oak Flats interchange.
Video of the Albion Park Rail bypass shows several instances where the divided lanes of traffic both cross over a road, rail line or river.
The RMS spokeswoman said, in those cases, they were counted as one twin bridge rather than two separate bridges.
Of the 13 bridges on the project, the longest is the 210-metre long twin bridge spanning the Macquarie Rivulet.
The shortest is an access crossing which is around 17 metres long.
Meanwhile, an information session on the bypass will be held at the Centenary Hall in Tongarra Road on June 13.
