I never understood this argument against more roads/bridges. Even if there is no improvement in latency (travel times), isn't the increase in throughput (number of people traveling) and the associated economic benefit worth it?

In addition to the counterintuitive traffic congestion stuff, you also have to consider cost. Bridges ain't cheap. Metro isn't either... but you could make a lot of improvements to Metro for the price of a bridge.

The 7000 series has fortunately been a godsend for Metro. Now it just needs a miracle for each of: power supply, rail insulators, water leaks, automated control, and the union contract/pension.

At the expense of turning cities into 1970’s-era concrete hellscapes where you need to drive to get anywhere.
