True - I had considered that, and indeed they
could do that to Port Wakefield Rd, but then they'd end up facing a similar sort of community protest as with the modifications to William St, Sydney following the opening of the Cross City Tunnel (apples and oranges, yes I know, but this is Adelaide - any measure aimed at directing motorists on to a toll road, however slight, is going to attract complaints)
No mention of tolls in this article today:

Noisy freight trains nudged out of north
A NEW transport corridor that will remove all noisy rail freight from Adelaide's northern suburbs has moved a step closer with the release of detailed plans and a route for the $1.19 billion project.
The proposed dual-purpose Northern Connector will run from Wingfield to the Northern Expressway on the western side of Port Wakefield Rd.
Depending on the funding, work on the 15km multi-laned freeway and a 31km rail line in the city's north-west could start in 2015.
The dual transport corridor has already been listed as a priority by the Federal Government and identified as a project of national significance by Infrastructure Australia.
Transport Minister Patrick Conlon said he was confident of winning federal funds for the project, which has a construction timeframe of about three years.
"The new rail link will, in the short to medium term, significantly reduce the freight rail travelling through resi- dential northern suburbs and link it directly to Outer Harbor," he said.
"The great opportunity with this project is we get to significantly improve heavy vehicle traffic efficiency and, at the same time, significantly reduce the volume of noisy rail from suburbs that have long had to endure the passing freight trains."
Mr Conlon said that in the longer term, the Government would work with industry to remove all rail freight from the northern residential suburbs.
"We are now at a point where a comprehensive three-year planning study has identified a preferred path for both the road and rail - a key stage in the process to secure funding for the project," he said.
The expressway, which will have three lanes in each direction, will join the Northern Expressway and Port Wakefield Rd interchange at Waterloo Corner with the Port River Expressway at the South Rd Superway interchange at Wingfield.
The rail track for freight trains, which will also carry the Ghan and Indian Pacific, will connect to the existing line at Kings Rd, Virginia and the Outer Harbor line at Dry Creek providing a more direct route for grain and mining resources for export from the port of Adelaide.
Mr Conlon said it would enable train speeds of up to 115 km/h, providing an efficient link between Perth, Adelaide and Melbourne.
The rail line will be raised on an embankment to flood-proof the infrastructure. The Northern Connector will also deliver a 3m-wide path for cyclists and pedestrians.
