Less Lighting on Maryland Highways?

I’ve noticed this winter that many lights on the highways I travel are not on. Particularly sections of Interstate 95 as well as the local 195 leading to the BWI airport.

I think this is a great idea for several reasons: uses less energy; reduces nightime “light pollution”, and reduces the impact of night lights on the nocturnal habits of many species.

I did some research and found that the Maryland State Highway Administration conducted a test along Rt 100 last winter. I could not find any updated info, but it’s definitely apparent they’ve extended the practice.

Wikipedia has a very informative page on light pollution & its impact.
