An FYI for you re: road construction.
Construction with asphalt (and especially concrete!) during a rainy season is not practical if you encounter near-freezing temperatures.
In buildings, you can enclose the structure to minimize the effect of too rapid cooling, and can get kerosene heaters to bring the temperatures into acceptable ranges. Not easy to do this with street/bridge work, especially if it still must carry traffic during the construction.
Ever wonder why roadwork in Las Vegas is usually at night? It ISN'T out of sympathy to the work crews - if its too hot (and dry), you can practically watch the concrete crack as it dries.
