The rusting Pont du Québec has been named a National Historic Site, however governments and CN Rail (the owner) have been unable to agree on who should pay to paint and repair

A bridge too far.. too far gone.

Well, OK, that’s a bit of an exaggeration. The Quebec City bridge is not beyond repair, not ‘too far gone”, but it is in rough shape.

The riveted steel structure is still the longest cantilever bridge in the world and was declared a National Historic Site of Canada in 1996.

This engineering feat had a rough start with a total and deadly collapse during construction in 1907, and another deadly collapse of the centre span during re-construction in 1916, with a total of some 88 worker deaths.

Now nearing it’s centennial. the road, rail, and pedestrian bridge is certainly showing its age, a victim of humidity and salt which is rusting and weakening the structure.

A Belgian expert on anti-corrosion visiting Quebec City this week inspected the bridge and told Radio-Canada news that the bridge was in a condition equivalent to those he had seen in developing countries.  To be fair, Bruno Saverys was in the provincial capital to promote his anti-corrosion products.

Nevertheless, photos show some disquieting rusting of the structure.

In a Radio-Canada report Quebec City Mayor Regis Lebaume is quoted saying that the erosion of metal can never be good, adding in French, “that’s the second European expert who has said there’s potential danger”, adding that in light of these comments, the situation “has to be taken seriously”.

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.
  8. Exchanging arguments and opposing views is a key component of healthy debate, but it should not turn into a dialogue or private discussion between two users who address each other without regard for the other participants. Messages of this type will not be posted.

  10. Making repetitive posts disrupts the flow of discussions and will not be tolerated.
  11. Adding images or any other type of file to comments is forbidden. Including hyperlinks to other websites is allowed, as long as they comply with netiquette. Radio Canada International  is in no way responsible for the content of such sites, however.
  12. Copying and pasting text written by someone else, even if you credit the author, is unacceptable if that text makes up the majority of your comment.
