And with that bus lane, tha bus is avoiding the traffic jam and getting people to their destinations faster and more reliably than the cars. Without it, we induce traffic. When we don't invest in active transportation, that bus gets stuck in the resulting induced traffic, which makes people think it's not a viable mode of transport for them, thus inducing more and more traffic, causing worse congestion for all.
Remember when you're stuck in construction in Edmonton, that the entire reason roads are being shut down all a once is because we are DECADES behind on sustainable infrasteucture for a growing city. We can only induce so much automobile traffic before our streets shut down, and we reached that point decades ago... but continued on despite because our freedom of transportation and the safety of those who use it, was politicized. If not for the wedge politics against active transportation lanes, this could have been spreadnot over decades, and did not need to be disruptive.
If you are railing against transportation alternatives, then you have no right to complain about traffic congestion. Traffic isnnot caused by construction. Construction is caused by traffic.
