It seems that the final stages of this work (expected to be finished by the end of December) will require night (7pm-5am) closures of these roads for profiling, asphalt wearing course and linemarking. Prohasky Street does not seem to be affected by the closures.
Details of the road closures and associated detours (which are rather complex) can be downloaded here. Allow extra time for the detours or just use Prohasky Street and/or Montague Street rather than Todd Road during this period.
In summary, the closures are:
- 19-29 November - Cook Street (one carriageway at a time)
- 27 November to 5 December - westbound (to Geelong) entry ramp from Todd Road
- 4-15 December - eastbound (from Geelong) exit from freeway
