Vertical curves along the Pan Philippine Highway

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.

Another look at the Bitukang Manok

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.

On the Tandang Sora flyover’s closure

The signs announcing the closure of the Tandang Sora flyover along Commonwealth Avenue are doing the rounds of social media. So are the traffic management plans (i.e., the re-routing maps for the area) that are being shared by many and soliciting a variety of reactions. The reactions are often angry or sad for those likely affected by the closure and the re-routing via Luzon Avenue, Congressional Avenue and Philcoa. The demolition of the flyover to give way to the future MRT-7 station will definitely lead to traffic congestion and longer travel times to a lot of commuters, whether using public or private transportation. However, there are only few comments so far about the impacts on pedestrians. Will the pedestrian footbridges be demolished, too? Will they be redesigned or replaced considering the high volume of pedestrians crossing this major intersection? Following are photos taken underneath the Tandang Sora flyover as we waited to make a U-turn. These show the pedestrian footbridges in the area that allow people to safely cross the wide Commonwealth Avenue.

There are many signs installed on the footbridge including the speed limit for Commonwealth Avenue and a reminder to fasten seatbelts. Others are directional signs including those designating the lanes for public utility vehicles and motorcycles.

There is another steel footbridge that is of more recent design and construction connecting to the old truss bridge. This allows pedestrians to continue on to cross Tandang Sora. This example is actually one that invites questions pertaining to design. Why have two distinct designs instead of building on the previous one? Another case of “pwede na iyan” ?

Here’s another view of the two footbridges – one spanning Commonwealth and the other across Tandang Sora. Will these be demolished, too, to give way to the MRT-7 station? And will the MRT-7 Station design include a provision for non-passengers to cross Commonwealth and Tandang Sora? This seems to be the most logical way to design the station; integrating pedestrian (and cycling) needs to the infrastructure. But then again, that remains to be seen and perhaps someone can share the design of the Tandang Sora station for this to be scrutinized.

Bitukang Manok

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”.

Looking forward to another long road trip

It has been a while since I had a long road trip. The last one was not particularly long as it was only until Lucena City in Quezon. Prior to that was a trip to Baguio City. And so I am looking forward to this trip to Bicol this week and I do hope to take a lot of photos along the way. That includes photos of arches that I have not had the chance of taking that I know I can get a lot of during this trip that will take us through several provinces in Southern Luzon. Those photos and the experiences from the trip will probably dominate the postings this February.

On the unpredictability of EDSA traffic

Much has been written about the traffic along EDSA, which is perhaps Metro Manila’s most famous (some would say infamous) thoroughfare. These include the unpredictability of congestion along this road. While it is hard to believe that traffic congestion is unpredictable for EDSA because very often it is congested, there are times when you just marvel that its free-flowing during the day or shocked that its packed with cars close to midnight. Last week, we experienced both predictability and unpredictability in the sense that we did expect EDSA to be congested near Ortigas (due to the dismissals of schools in the vicinity) but didn’t expect it to be packed during what we thought was “alanganin na oras” that was around 3PM.

Interestingly, there was no congestion after Ortigas Avenue and we quickly made up for the time lost in the congestion we experienced from Gil Puyat Avenue. Is this another case of the phantom congestion where the simple disturbances in the traffic stream can create a ripple effect resulting in congestion? Or is this somewhat like an everyday thing? EDSA is not part of my daily commute so I am not so sure about the regularity of this situation but at least the weather didn’t factor in the equation. Heavy rains usually lead to flash floods along this thoroughfare, and these floods will definitely lead intense congestion.

More on ads masquerading as signs

I recently wrote about what I thought were ads masquerading as signs. It turns out a friend also took notice of similar signs along Katipunan and decided to make this a topic of his vlog. I learned that he has corresponded with the MMDA regarding this matter and even contacted the company behind these ads (I would prefer to call them what they really are.) to get their take on the matter. It turns out that the company is quite aware that what they are doing are basically not according to DPWH guidelines pertaining to signage. I wouldn’t and couldn’t say it is illegal since the MMDA and LGUs gave their approvals for these ads to be installed.

 

Approaching Cainta Junction from Antipolo, there is a sign that advertises Cherry Antipolo, which is all the way back and past Masinag Junction along Marcos Highway.

Less than a kilometre away from Masinag Junction along Sumulong Highway, there’s another ad posing as a road sign and from a certain angle it covers a more important traffic advisory concerning the construction of the Line 2 Extension.

This ad doesn’t even pretend anymore since all directions point to an Ayala Mall!

Following are examples of what may be tolerated and what must be disapproved and therefore removed. Guidelines are important so that the criteria for signs including ads masquerading as such will be clearly spelled out and approval/disapproval will not be

Logical: The photo below shows a sign installed by the DPWH showing the general directions for towns (Cainta, Taytay, Antipolo) or major thoroughfares (EDSA). The smaller sign is actually an ad for a mall but is located near a major junction (Cainta Junction – intersection of Ortigas Avenue Extension and Felix Avenue/A. Bonifacio Avenue) and may perhaps be tolerated as the mall is close by. Such a sign can be justified to assure or validate the direction to be taken by a traveler headed for this mall.

Not logical: The sign below is meters away from Masinag Junction in Antipol but advertises the same mall as the previous sign. It is not logical and should not have been approved since it is far from the destination mall and does not offer a validation or assurance for direction like the previous sign. In fact, the same mall chain has a branch nearby in the Masinag area and another one further on along the Marikina River. This sign should be removed as it adds to the clutter, the visual noise that makes people blind or numb to the actual road signs that require their attention.

 

[Disclaimer: For purposes of transparency, my colleagues and I also have worked as consultants for projects such as malls but never have we recommended for signs like these.]
