What’s been causing some traffic congestion along Ortigas Ave. Extension is the collapse of a side of the mountain at a section just before the Antipolo City arch (if you’re coming from Tikling Junction). The soil probably was already saturated after the past few days heavy rain and it didn’t help that the old wall holding the soil and consisting mainly of blocks was also already weakened (I am assuming that it was built following standards for such walls.).
The area had been partially cleared of soil and rock, which initially blocked 2 lanes of the 4-lane road. Kudos to the DPWH for their work clearing part of the debris and easing traffic along this busy thoroughfare.
The wall at this section was completely obliterated revealing soil that appeared to be already unstable.
Hopefully, funds can be allocated very quickly in order to build the necessary slope protection. Perhaps the barrier should be designed to allow for more water to seep through without compromising the structure. Such weep holes are necessary especially given the saturated soils due to heavy rainfall experienced during this wet season and others in the future.
