It will come down to cost to build and time to build...
I took 2 tunnels to and from the airport today. Each way, over $10. But I'm damn glad I took them because they go all the way from north of the city, to south of the city, including under the river, where our bridges are massive bottleneck.
I saved at least 30' and a lot of sanity, and this was before work. I'd be dead tired if I had to deal with traffic jams for 45'.
Heck I'd even chose a bumpy tunnel over the surface.
Sounds a lot like it. I used to commute from Alexandria to the North Shore, and though I couldn't afford the Eastern Distributor every day, I did like that it was always there if I was in a hurry to make an appointment or if I just wanted to treat myself.
