When you're search for information on Canada, remember ".ca" As in google.
www.google.caNow, specific:
http://en.wikipedia.org/wiki/Trans-Labrador_Highway gives you a history of construction and is moderately up to date re. type of surface.
There is also the NL (Newfoundland & Labrador) government information
http://www.roads.gov.nl.ca/cameras/trans_labrador.stm& most importantly for any travel in NL.
http://www.roads.gov.nl.ca/cameras/, not just because it gives road cameras online, but because it gives links to so many travel information sources. Memorize that one and you can use it anywhere with anyone's computers.
FWIW, I lived in NL for 24.5 years. ending in 2008 and talk/e-connect with people there regularly.
Please see my signature for 2006 trip pics.
