It used to be driveable until the bridge went out. Drove it many times. So many major screw ups that it is unlikely to be what we would think of as a "ring road". Just a bunch of back roads to avoid the downtown traffic.
Here is some more info about the area being opened for the road to proceed. Oscar and Rosario Yutangco-Torres family donated the years-long unresolved obstacle in the south diversion road in Junob that paved and cleared the way for a four-lane highway from Bacong to Sibulan. The Mangacop family also gave way of their fence to let the City diversion road pass. Thanks to the families said Councilors Lani Ramon, Michael Bandal, Jose Kenneth Arbas and Karissa Tolentino who witnessed the demolitions led by Mayor Felipe Remollo who took only two weeks to clear the way “with gentle persuasion.”
This road is years from being finished,only about 25% is anywhere near finished. The road will run from bacong to sibulan,so dont hold your breath as phil south are the contractors as usual.
