Halifax Airport fog issues

With amazement I’ve been following Halifax Airport’s fog problem. I don’t understand (hey kids, spot the truck in that picture!):

First of all, the airport decided to start construction to one of its runways in the busiest portion of the year. Secondly, the airport only has to close down during fog, because planes cannot the construction forces them to turn off the ALS.

I heard this particular problem may be lasting for three weeks: that’s when the airport hopes to have finished the construction. For now, lets just hope it’s only going to be foggy in the morning and during the weekends.
