A report to council last week said Marathon Loop could be opened at the eastern cul-de-sac end on to Gnangara Road in an effort to ease the frustration of locals at the Buffalo Avenue exit.
The City would also create a left in/left out only intersection at the western end of Marathon Loop.
The report said alternative access to the pocket of residential properties in the precinct needed to be considered.

READ NOWIt said that traffic congestion and demand on the Buffalo Avenue exit had worsened due to further development and population growth in the area.
Infrastructure acting director Harminder Singh spoke to councillors about the issue at last week's briefing.
It follows his letter in the Weekender on April 30 addressing residents' concerns about the realignment of Gnangara Road.
He said the City had allocated funding for the project in its capital works plan but it was dependent on Main Roads WA (MRWA) approval.
Mr Singh said the City was working with MRWA to progress approval for the preliminary design work undertaken by the City for intersection works at Whitfords Avenue and Wanneroo Road.
"In the absence of the Gnangara Road realignment, the City has also considered other options that may be available to the City to alleviate residents" concerns," he said.
"This could include opening the existing Marathon Loop access on to Gnangara Road or any other access options subject to a traffic impact study and community consultation."
He said they would also liaise with MRWA to reduce the speed on Gnangara Road between Wanneroo Road and 150m east of the Marathon Loop intersection.
"The City is dedicated to listening to residents and working to find solutions to issues in the community," he said.
The proposed works are estimated to cost about $200,000.
