A couple of notes.
I think that the trackage between Sudbury and the Soo would require further upgrades to achieve speeds to make it worthwhile.
I agree with your comments re connectivity of the existing services with those proposed (either building or conceptual)
I think you will see additional twinning to 17, and additional passing lanes.
But I think one of the greater and needed requirements is for enhanced transport truck driver certification with more rigorous requirements, more inspections and mandatory refresher/recertification at periodic intervals.
See the EU requirement:
Code 95 (The CPC Certificate)
The
Certificate of Professional Competence (CPC), recognized on your license as Code 95, is the single most important document for any driver in the EU.
- The “12-Hour Rule”: Legally, you cannot drive a commercial vehicle for more than 12 hours a week without this qualification. It is the proof that you have been trained in modern safety, fuel-efficient driving, and load-securing techniques.
- Initial Qualification: For new drivers, this involves an extensive course (often 140 to 280 hours) followed by a series of theoretical and practical exams.
- Periodic Training (The 35-Hour Rule): Your Code 95 will expire. And to keep it valid, you must complete 35 hours of accredited training every five years. You must do this to keep up to date on the latest regulations, road safety tech, and “eco-driving” standards to reduce environmental impact.
