What's your favorite color?

There has been a lot of discussion lately regarding the new I-35W bridge. No one really seems to know what governs the color of the bridge lights at night. For the majority of winter, the lights were blue. But some people have also seen red, white, and green. Looking online I was not able to actually find an answer and I was not satifisied with the "it depends on the outside temperature" explanation.

So I took the my digging to the next level and emailed the director of communications for MnDot. Here was his response:

"Sam,

In all honesty, it is somewhat arbitrary.

We haven't established a protocol for determining color. We used the blue for awhile. We attempted the green prior to St. Pat's day, but couldn't make it work. It has been green since, I think.

We will use some other colors in the future. I expect that we will develop a policy regarding the use of color."


Answer solved.
