Orange / White Airport Barriers

This post is for those of you who traveled over the holidays and noticed the orange and white airport barricades on the runway and wondered what their purpose was.  Most likely they had one or two red lights that were blinking on them, and possibly a flag or two.  These are used almost exclusively on airports that are under construction.

They are to warn pilots that the runways in under construction  and the lights make them easier to be seen.  The short height and long width make them perfect for being placed right down the runway.  You won’t typically see them on working runways though it can happen.
