We start the month of March with a compilation of photos of vertical curves (mostly sags). These were taken along the Andaya Highway, which serves as the main bypass road in Camarines that allows travellers to bypass, for example, Daet.
These photos do not have captions and I leave it to my readers to have an appreciation of the features of these sections. These include wide carriageways with paved shoulders. There are also sections that have no shoulders. For most photos, the pavement appears to be in good condition. However, the same cannot be said for much of the highway, sections of which are being rehabilitated along with several bridges.
I recently featured photos of the old zigzag road along the Pan Philippine Highway that is more popularly known as the “Bitukang Manok”. Those photos were taken on an early morning while we were on our way to Bicol earlier this month. Following are photos of the old zigzag road taken on the afternoon of our return trip to Manila.
Crossroads – at the intersection at the southern end where travellers decide whether to take the Bitukang Manok or the newer and easier bypass road
The sign states: Vehicles with 6 or more wheels are prohibited from using the old zig-zag road.

Here’s a photo of one of the more challenging sections. A team of flagmen manage traffic by giving turns to either direction, ensuring slower speeds and wider turning at the hairpin curve. Travelers often toss coins as a token of gratitude for these flagmen who man this challenging section of the national highway 24 hours/day.
The barriers and signs along Bitukang Manok have been upgraded and are well-maintained.

I woke up from a long nap just before we entered a major zigzag section of the Pan Philippine Highway that is more popularly known as the “Bitukang Manok”. That literally translates to “chicken innards or intestines”, which is how many travellers would describe the alignment of this section of the national highway network. We decided to take the “old zigzag road” instead of the “new diversion road” since the latter is known to be already congested especially as trucks and buses take this road instead of the zigzag.
Expectedly, the road offered all kinds of curves and grades throughout. I was glad to see relatively new barriers already installed or constructed along the entire length of Bitukang Manok.
Here is a particularly challenging section combining sharp hairpin curves with steep inclines.
We caught up with this rider along a relatively straight and level segment of the road
There are flagmen strategically deployed along the most difficult parts of the road including this one that might lead inexperienced or erring drivers to drive/ride straight off a cliff.
Here’s another hairpin curve; this time on the way down from the mountain.
The final turn of the road before it merged with the diversion road
Sign at the other end of the road showing travellers the divergence of the national highway into the “old zigzag road” and the “new diversion road”. Notice the platoon of southbound trucks at right.
I remember Bitukang Manok as a dreaded section among travellers before not just from the safety viewpoint but also because many can get sick (e.g., motion sickness that may result into throwing up) going through the section especially if the driver is not as smooth in manoeuvring the vehicle through the zigzags. There were also long distance bicycle races before where the Bitukang Manok featured as the main challenge to the best cyclists and the winner of that leg of the race was pronounced as “king of the mountain”.
The recent news about the groundbreaking for the C-6 expressway led some people to this site and looking for information on C-6. Here are more photos I took last month (January 2018):
The future northbound lanes of C-6 is currently under rehabilitation and are being upgraded to Portland cement Concrete Pavement (PCCP). The new southbound lanes currently serve the two-way traffic.
The sign is an old one and perhaps still in use as a barrier more than for information
You see a lot of people jogging, walking and cycling along the finished road. It shows the demand for spaces for such activities, including recreation, and a similar situation may be observed along C5 before and along the perimeter of Libingan ng mga Bayani where a lot of people do exercises and other activities along road sections that are closed to vehicular traffic.
With one lane completed the second lane is prepared for pouring of concrete. You can see the formworks along the median.
Other sections have yet to be prepared for concreting but have been stripped of the old pavement (Asphalt Concrete pavement or ACP).
What you see here at right is the compacted base/sub-base layer. The forms have not been installed yet.

I will post more photos later from the next time I pass by the area. From what I’ve hear so far, traffic has eased along the expanded Barkadahan Bridge but there are still bottlenecks to address along this alternative route. There will also be a need to have a higher capacity, less friction connection between C-6 and C-5 as traffic along C-6 increases and it’s become quite obvious that Taguig’s narrow streets cannot handle this increasing travel demand between the two highways. It makes sense to have a higher quality, limited access road for this purpose since Taguig roads are already congested and through traffic poses a safety hazard to the residential areas where vehicles travel through.
I have not used Circumferential Road 6 in a while. And so a couple of weeks ago, I was happy to see that work has resumed on the sections at Lupang Arenda in Taytay, Rizal, which is also known as Sampaguita Street. Here are some photos of the wide C-6 section. I guess there’s an opportunity here to have service roads on either side of the highway in order to manage/control local traffic. C-6, after all, is a highway and is designed for typical national highway speeds (i.e., 60 kph). The adjacent land use, however, requires slower traffic mainly due to safety concerns.

Another photo of the section showing form works for the slab. Note the parked vehicles along the side on the left.
Some sections are already flooded from the heavy rains
The completed section towards Nagpayong, Pasig is a wide 4 lanes. At left is a nice view of the Laguna de Bai.

That’s a habal-habal (motorcycle taxi) terminal on the left and in front of a parked jeepney.
Two very important things about C-6 though. One concerns the Barkadahan Bridge over the Manggahan Floodway, which is too narrow for the traffic that cross it. There’s a new bridge beside it that seems to be taking too long to build. And then there’s the long stretch from Nagpayong, Pasig to Lower Bicutan, Taguig which remain in bad condition. The new section along the lakeside is already usable for Pasig-bound traffic but needs to be allowed to carry two-way traffic for the older section to be rehabilitated. C-6 is becoming a major alternative route for a lot of travelers from Rizal to and from Makati and Taguig (esp. BGC). It needs to be improved immediately as it can help decongest the Ortigas Ave. – C5 route that most Rizalenos use to go to their workplaces.
There are hazardous worksites along Sumulong Highway. These are related to current drainage works and construction of pedestrian facilities (sidewalks) along the highway. Travelers can see the steel reinforcing bars (rebars) sticking out and posing risks to road users. Following are some photos we took as we traversed the stretch near La Montana, Palos Verdes and Cavaliers Village.

More hazardous worksites
These pose dangers to most road users and especially motorcyclists and cyclists who may experience a spill that can lead to riders being impaled by the rebars. The contractor definitely is violating safety codes in as far as construction sites are concerned and these are in plain view of the public. The DPWH as well as the local government of Antipolo City should act immediately and decisively in order to prevent untoward incidents concerning such worksites. There should be measures such as physical barriers that would protect road users against such hazards. There are currently none.
I had not been to Baguio City for quite some time until June of 2016 (last year). And so I took a lot of photos of the roads between Metro Manila and Baguio including the three expressways (NLEX, SCTEX and TPLEX) and Marcos Highway. I have only posted photos of Marcos Highway ( a lot of them) and haven’t come to downloading photos of TPLEX that I have taken during my first time along the entire stretch at the time. To sort of make up for the backlog, I am posting the following photos of Kennon Road that I took almost 7 months ago. I assume most if not all roadworks along Kennon Road that some of the following photos show are already completed. I will no longer write captions for each of the photos but there are many landmarks shown here that can help the reader in his/her sense of direction and orientation. The following photos are of Kennon Road from Rosario, La Union to Baguio.
More photos from that June 2016 trip soon…
