If I understand what you are saying is you are suggesting that they narrow the right of way for the ultimate design and repurpose the median to host the utilities.
Is that right?

I would prefer that the highway is as narrow as possible, to maximize land use, minimize destruction to the environment, and reduce cost. Furthermore, I think we should make it our goal as a city to never ever ever ever need 16 traffic lanes there. 8 should more than suffice (6 plus room for LRT should be more than enough), and if we need more, we've failed as a modern city.
As this leg of the LRT is about 30 km long, a
300 m ROW consumes 9 000 000 m2 or 2224 acres, much of which contains pristine ecosystems rare in other parts of Calgary. Reducing the width by even 1.5 m can save an acre.
More than just environmental concerns, this highway will consume developable land valued in the hundreds of millions, particularly between highway 8 and OBCR. A 300 m ROW obliterates pedestrian transportation across the highway, whereas a 60 m ROW (the minimum required for a pipeline - enough to fit 6 traffic lanes and an LRT, like Bow or Crow) would enable future residents (in Evergreen and Springbank) to cross on foot.
The wider the ROW, the longer interchange spans must be, the further future residents will have to commute, and the more expensive this project will be.
Every meter of ROW counts, and we should use as little as we can. Constructing 109 m medians so that we are prepared in case we one day need 16 lanes is ridiculous and wasteful - even if it is standard practice elsewhere in AB. I'm not saying we need to achieve a 60 m right of way (although I believe we can, and in fact that cost savings and land use benefits would outweigh vertical integration of utilities), but surely there is a way to use less than 300 m and $5B. One such alternative might be to put utilities in space wasted by medians.
