We have the same in Leeds - a mindless ongoing project to reduce road width and usage and replace with dual pedestrian and cycle lanes. The council are just embarking on their latest brainless scheme to redesign the main arterial entry point onto and off the city's urban motorway. The plans will cause disruption for two years!
The end result, one roundabout less, fewer lanes for cars, nice cycle lanes and dedicated bus lanes. Yet the majority of traffic entering and leaving Leeds uses this route.

My theory is they don't want people using cars, full stop.
You can't travel into the city centre in a car as there are dedicated bus/cycle/taxi (not private hire) routes. Cameras in case you enter into them, and more shops boarding up windows as their trade has gone out of town, or online.
I often wonder how many of the planners use cars or are they all vegan munching, rainbow loving, tree hugging cyclists ?
