Roads and Maritime Services had placed the concept design up for public consultation, which ended earlier this month.
The design allows for a northern entrance to the University of Wollongong, as well as grade separation for heavy vehicles and a service road connecting the motorway to University Avenue.
There is also an overpass replacing the dangerous right-hand turn from Old Mt Ousley Road onto the motorway.
Feedback delivered online regarding the interchange has included concerns about whether it will have any effect on traffic heading to the university.
A 2016 report on the interchange identified the university’s effect on traffic in the area, tagging it “a significant traffic generator”.
It found there was an average of 1660 vehicles entering UOW during the morning peak and was at its highest prior to the first morning lecture.
Some of the concern about the northern entrance related to whether it would be useful, given the large number of vehicles parking in suburban streets around the campus.
“There is limited parking in the university so there is no point directing university traffic into the centre of the university unless the university parking issue is addressed,” one respondent stated.
“The students travelling from the south will not use the new off ramp as most of them park on the Keiraville/Gwynneville streets.”
A University of Wollongong spokesman said it supported the idea of the northern entrance but was concerned about its effect on traffic.
“The university does have some concerns about the potential impact on traffic within the campus internal road network including impacts on the experience of staff, students and visitors on campus, including safety and amenity,” the spokesman said.
“UOW has made a submission to Roads and Maritime Services as part of the public consultation process and will work with RMS and other community and project stakeholders to resolve those concerns.”
