We are currently implementing a project to improve the safety of journeys of children between their homes and schools. Ocular surveys of 25 schools in Zamboanga City revealed a lot of issues pertaining to their commutes. Critical locations include the main access roads (e.g., across school gates) and intersections. All schools have reported incidence of road crashes involving their students and mentioned that in many cases, drivers or riders do not slow down upon approaching the critical locations. These cases of speeding are despite the many countermeasures (including informal and creative ones) that schools and Barangay authorities have implemented to improve safety.
Here are some photos we took at Sinunuc Elementary School along the national highway in Zamboanga City:
Children waiting to cross the highway and on-board motorcycles with their parents/guardians who fetched them from school
Large vehicles including trucks and buses traverse the highway and the signs offer little in terms of refuge or protection against these for students and other people crossing the highway.
Child crossing with a parent/guardian
Children crossing the highway – photo also shows a pedestrian crossing sign at the road side along the direction towards the city centre.
Children crossing with their parents/guardians as a jeepney is stopped right before the pedestrian crossing.
Though it may not be so obvious for some observers or viewers of the photos, these situations present high risks for students and others using the roads. And we hope our assessments in cooperation with the schools, agencies and city officials will be fruitful in improving road safety especially for the children.
Here’s one of those quick shares that I usually post here. I am a bit of a history buff and mixing that with transport will likely lead to a post like this. Here is a short article about an event in the history of the US Army that happened 100 years ago:
email@example.com (2019) Celebrating Highway History: The US Army’s 1919 Cross-Country Convoy, aashto.org, https://aashtojournal.org/2019/07/12/celebrating-highway-history-the-u-s-armys-1919-cross-country-convoy/ [Last accessed: July 12, 2019]
The article was particularly interesting for me because of two items: the road conditions and the man behind the US inter-state highway system. It took them a little over 2 months to cross the continental US because of poor road conditions. Many people have no sense of history and appreciation of what has been accomplished over the years and how difficult it was to travel at the time. I haven’t done the cross country trip but I have close friends who’ve done it and are thankful for the generally good roads they could use for the experiential road trip. Meanwhile, the person in the article – then Lt. Col. Dwight D. Eisenhower – is a man who made his mark in history at first as the Supreme Commander of the Allied forces in the European Theater in World War 2, who would later on become President of the US. I read elsewhere that the US interstate highway system was designed so aircraft may use them as runways in cases when the US were at war and the enemy had bombed their airports and airfields (just like what the Japanese did in the Pacific).
Do we have similar accounts for our roads and bridges in the Philippines? Were there key persons who may or may not be larger than life figures instrumental in developing our road infrastructure with their vision and leadership (Marcos doesn’t count because of his bogus military record and corrupt regime)? It would be nice to compile these and perhaps it should be a collaboration between the Department of Public Works and Highways (DPWH) and the National Historical Commission (NHC). They could even get the history departments of local universities involved for us to understand the evolution of transportation in this country.
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.
Sign for the Quezon National Forest Park – this designation is attributed to a former President and local congressman
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.
Approach to the northern end of the old zigzag road
Directional sign at the other end of Bitukang Manok showing the options for travellers and another advisory stating the prohibition of large vehicles along the old zigzag road.
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.
Section to Nagpayong near the boundary of Taytay, Rizal and Pasig City.
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.
