I’ve featured the controversial C-5 Road Extension before and there is still a long way to go before the full circumferential road will be completed, linking R-1 Road (or the Coastal Road) all the way to R-9 (or the MacArthur Highway). Complementing the C-5 Road is the C-6 Road, which is an even bigger circumferential road that will mostly lie outside Metro Manila. This road has the working name of Bulacan-Rizal-Manila-Cavite Regional Expressway and may be named as the Padre Jacinto Zamora Super Highway.
Construction has already started and visible portion is in Taguig City. It’s still not completely open to traffic because the surface is still unpaved but joggers, runners, bicycles, and tricycles have been known to use the road already. Currently, the southern terminus is at Barangay Lower Bicutan in Taguig and connects with the intersection of M.L. Quezon and Gen. Paulino Santos Avenue. From here, the nearest major intersection is the Bicutan exit of SLEx.
Just like with the C-5 Road, we can expect the completion of C-6 Road to be fraught with lots of delays and tons of problems. Buying the right-of-way will definitely be a huge impediment and that’s not counting the bidding of construction which are often corruption magnets. If you’re interested, go to the C-6 Road thread at the SkyscraperCity Forums to follow up on the developments of this road. (Plus they have tons of pictures and maps to help illustrate the discussions.)
