MRT 7 (north edsa-SJDM)

... "at grade" levels? It's an EDSA MRT fail we should have learned from before.

This is new to me. What do you mean?

The tracks will be on the same level as the road at some portions it seems. If you look at EDSA MRT, we lost one entire lane through most of EDSA because of this design.

Mas masaya siguro kung parang trams in Europe and SF ang at-grade nila sa QC circle hehe. Patintero tren, bus, jeep, motor, bike, at jaywalker wooohooo!!!

But isn't Commonwealth wide enough to lose at least one lane without affecting the traffic much?

siguro naman makakatulong makabawas ng trafic at Pollution pag natapos ang mrt7...pagnagstart na ang construction lahat po ng mga driver dadaan jan magbaon ng mahabang pacyensya baka ubusin daw ng DMCI ang pasyenxa ng motorista hehehe

Yes, Commonwealth is pretty wide but why narrow it? We should be thinking ahead that with an MRT on that route, it will be another major gateway to the vast tracts of land in Bulacan which will be eventually another "bedroom"of Mega Manila just like Cavite and Laguna.

Imagine how crazy QC circle would be with that scenario.

Ahh.. got it. I think this has to do with the need for the train tracks to be as level as possible. I would imagine that electric trains does not like steep gradients by physical limitation and/or design. Most of our roads, including the whole length of EDSA have slopes and grades that trains simply can't follow. So they designed the whole track to sort of follow a relatively level grade throughout. So you'll see some parts of the track elevated, while seemingly underground on some segments.

Rumor has it that the MRT3 Buendia-Ayala stretch was supposed to be at-grade but the powers-that-be who live in the subdivisions in that area do not like hoi pollois peeking into their backyards :P

Or it could be because of the Estrella flyover

ok siguro if they would put the railway on the right side of quirino highway para di mabawasan yun daan..tsaka small numbers of tress lang naman ang mapuputol dagdag nature attraction pa besides elevated naman yun railway...
probably Bulacan will be eventually another "bedroom"of Mega Manila..

@EDSA, AFAIK it was purely cost reasons why it was designed "at grade". Word is that it goes underground in Makati (Buendia - Ayala) because Forbes and Dasma reprezent objected to the elevated stations and noise it would bring to their turf.

Commonwealth Avenue is pretty flat really; EDSA has more drastic elevation changes it seems.
