My gosh. And how bad will the traffic get before that thing is finished? I shudder to think of Edsa becoming like Quirino, Araneta or A. Bonifacio. Probably even worse.
I think aside from trying to make more space in the metropolis, they should absorb more cities along NCR borders into Metro Manila. This way they would literally make more space in Metro Manila, encourage further development and investments, and disperse more of the people squeezing into Metro Manila because of the higher wage rates.
