South Road Tunnel Hindmarsh to Port Rd

Just wondering why there seems to be no activity on the promised South Rd Tunnel from Manton Street through to Port Rd?
With all the heavy earthmoving equipment gone from the Anzac Highway project, why are they not using it on the promised tunnel project?
Is it perhaps a case of yet another project promised and given advertising in the public domain that has now been shelved?
