Canada now officially connected by road-coast to coast to coast

It’s official. For the first time in Canadian history, the country is now linked by all-weather road from Atlantic to Pacific, and now to the Arctic.

Yesterday the final 137 kilometre section of an all-weather road linking Inuvik in the Northwest Territories to the Arctic coast hamlet of Tuktoyaktuk and its some 900 souls was officially opened.

The route of the new road gives an idea of just how difficult is was to build around the many ponds and lakes and over permafrost, rivers and streams.

The new two-lane road joins with the Dempster highway which ended in Inuvik and now completes a north-south road in the country. It involved a number of innovative technologies such as a geothermal matting over the tundra to reduce potential melting of permafrost before the road ballast was laid on top. Several new materials were also used in what is an ongoing experiment of building in the high Arctic.

Other circumpolar nations have also been watching the process, methods, and materials with interest for their own similar future projects.

Previously “Tuk” was serviced only for a few months in winter over annual ice-roads.

Built at a cost of some $300 million, the new Inuvik-Tuktoyaktuk McKenzie Valley all-weather highway is expected to help with development in the north. However, a damper has been put on the original expectations as the Canadian government had put a five-year moratorium on offshore oil drilling in the Beaufort Sea.

While some say there’s still hope for gas exploration and possibly the Mackenzie Valley gas pipeline, but others say given the changing marketplace, that may never happen.

What is more likely is that with easier access all year for goods, the cost of living in the region will come down and will likely open up more opportunities for tourism for several nearby hamlets.

The road though complete and opened, will require ongoing maintainance as the “living” landscape moves, melts, and freezes.

Netiquette »

When you express your personal opinion in an online forum, you must be as courteous as if you were speaking with someone face-to-face. Insults and personal attacks will not be tolerated. To disagree with an opinion, an idea or an event is one thing, but to show disrespect for other people is quite another. Great minds don’t always think alike—and that’s precisely what makes online dialogue so interesting and valuable.

Netiquette is the set of rules of conduct governing how you should behave when communicating via the Internet. Before you post a message to a blog or forum, it’s important to read and understand these rules. Otherwise, you may be banned from posting.

  1. RCInet.ca’s online forums are not anonymous. Users must register, and give their full name and place of residence, which are displayed alongside each of their comments. RCInet.ca reserves the right not to publish comments if there is any doubt as to the identity of their author.
  2. Assuming the identity of another person with intent to mislead or cause harm is a serious infraction that may result in the offender being banned.
  3. RCInet.ca’s online forums are open to everyone, without regard to age, ethnic origin, religion, gender or sexual orientation.
  4. Comments that are defamatory, hateful, racist, xenophobic, sexist, or that disparage an ethnic origin, religious affiliation or age group will not be published.
  5. In online speak, writing in ALL CAPS is considered yelling, and may be interpreted as aggressive behaviour, which is unpleasant for the people reading. Any message containing one or more words in all caps (except for initialisms and acronyms) will be rejected, as will any message containing one or more words in bold, italic or underlined characters.
  6. Use of vulgar, obscene or objectionable language is prohibited. Forums are public places and your comments could offend some users. People who use inappropriate language will be banned.
  7. Mutual respect is essential among users. Insulting, threatening or harassing another user is prohibited. You can express your disagreement with an idea without attacking anyone.
