Your forgetting, I'm talking about either two lanes of traffic in one tunnel or one lane of traffic in two tunnels.
First order analysis says there is no saving by using two tunnels instead of one. When you consider 4 one lane tunnels vs one tunnel with four lanes of tunnels, the four tunnel solution is worse.
