Is it purely for aesthetics? Safety reasons? Better lighting? To allow for greater solar snow melting in winter? Cheaper? Better sound abatement?
Thanks.
It's for aesthetics. More specifically, it's to help eliminate a 'canyon' effect due to the length of the barrier on both sides of the highway.
The MTO installed similar transparent panels on the QEW a few years ago in St. Catharines: http://www.asphaltplanet.ca/ON/QEW_image..._24x16.jpg
