Road and drainage works along Soliven Avenue, Antipolo City
Traffic has been quite terrible for people living along the Marcos Highway corridor and it doesn’t help that one option via Marikina is also currently congested. I am talking about the stretch of Sumulong Highway between Masinag and Soliven Avenue, which is currently being rehabilitated with drainage and pavement works. The work seems to be progressing but not as fast as most commuters would want it to be. Complicating things are more serious road and drainage works along the Antipolo section of Soliven Avenue. This has rendered the street to become one-way and from what I have seen, work here is proceeding much more slowly (perhaps excruciatingly for those residing or working along this stretch). Following are photos I took of Soliven Avenue from the intersection with Sumulong Highway to the border with Marikina City where Soliven Ave. becomes Lilac Street. I won’t put any labels anymore and let the photos speak for themselves.

Hopefully, these road and drainage works can be completed very soon and would allow for the alleviation of traffic along these roads and the alternate route between Antipolo and Quezon City via Marikina. Such will also help ease congestion along Marcos Highway.

Roads to Baguio: Marcos Highway – Part 2
To open September, I continue on the feature on Marcos Highway. Following are more photos I took on our way back to Manila from a short vacation in Baguio.
Many sections of Marcos Highway have some form of protection against landslides or rock slides. Note the concrete faces fences along the left in the photo.
There are many structures along the highway including houses and stores
The mountain limits sight distance along curves like this.
We encountered this group of motorcyclists heading up to Baguio on what appeared to be what is termed as “big bikes”, that typically are the more expensive ones, too. Other photos in this series will show these motorcycles. I lost count of them while we were traveling the opposite direction.
This seems to be a popular stop for hungry travelers. The location though and its driveway are not at all desirable from the highway engineering perspective.
Combination of signs to guide motorists along this sharp curve.
Curved sections like this one offer breathtaking views of the mountains.
Shoulders may function as space for emergency stops including for breakdowns or changing tires. Full shoulders allow for stopped vehicles to be completely clear of the traveled way. That is, they don’t pose as obstacles that traffic would need to evade.
More examples of poorly located establishments along a curve
The road seems to disappear in the mountains
Another home along the highway and right at one of the curves. This one seems to be wisely located behind the barriers though its pretty obvious where their driveway is located.
Conspicuous location for a religious site along the highway
More motorcyclists and their big bikes
Barriers along both side of the highway seem sturdy enough to keep vehicles from flying off the road in case their drivers/riders lose control. This section offers enough to satisfy sight distance requirements and noticeably does not feature double yellows like the other photos in this post.
A residential community along the highway including this big house just clear of the shoulder.
Another community including a home atop the mountain. The barriers appear to be newly constructed along with the PCC paved shoulders. These would have to be painted for them to be visible to motorists especially at night-time or when visibility is poor.
More photos of Marcos Highway soon!

Roads to Baguio: Marcos Highway – Part 1
In my recent trip to Baguio, I made sure to take new photos of roads particularly the major ones that made that city in the mountains accessible. Of course, one objective was also to have an updated selection for my highway engineering lectures. Following are the first batch of photos I took of Marcos Highway last June 2016. I won’t be writing a caption for many of these photos as well as those in the succeeding batches. I’ll just put these here for others to refer to whether for practical uses or for research.
I found it unusual to see double yellow along a relatively straight and level section of Marcos Highway. It is perhaps a section where there have been a significant number of road crashes?
There are many roads built to provide access to areas previously uninhabited but now have houses giving some spectacular mountain views.
There are rumble strips along many sections of the highway; seemingly there to wake up travelers that where getting sleepy.
It can get quite foggy along the highway
Old barriers look sturdy enough to prevent heavy vehicles from falling off the highway.
One end of the viaduct alongside the mountains
There are communities in many places in the mountains along the highway. Access would be via local roads, some of which are private roads.
I thought perhaps bridges and viaducts in the Philippines should have shoulders and more generous space for pedestrians.
The van in the photo enters the highway from one of the many driveways and local roads connecting to the national highway.
What appears to be a tunnel for many people is actually a roof structure to protect travellers and the road from landslides.
During the day, it is bright inside the structure given the openings along one side of the highway.
The light at the end of the tunnel?
More photos in Part 2 coming up soon.

Evidence from Montreal: Building bike lanes to reduce car use
I just wanted to share this article showing evidence of car use reduction (and therefore, car traffic along roads) with the provision of bicycle lanes.
Building Bike Lanes Really Does Get More People Out of Their Cars
The article though cautions readers against generalising or assuming great improvements. Some figures mentioned in the article including the following (I took the liberty of copying and pasting):
- “A 10% increase in bike accessibility resulted in only a 3.7% increase in ridership.”
- “…cycling infrastructure also reduced greenhouse gas emissions from cars by 1.7%, a reduction equivalent to converting transit buses to hybrids and electrifying commuter trains.”
These numbers are for the case of Montreal, Canada. Not mentioned are the number of cyclists, vehicle traffic volumes and other pertinent data that are useful in analysis. The article correctly points out the importance of using science (e.g., sound analysis based on good data) in order to convince governments to put up bicycle infrastructure. I would even add that this approach should also be applicable to pedestrian facilities.

Dang Bakal road widening in Antipolo
We go to church at the Parish of the Immaculate Heart of Mary along Daang Bakal in Antipolo City. Quite obvious is the current road widening project being implemented along Daang Bakal. While the improvement of the road was welcome, my opinion is that widening the 2-lane road to 4 lanes was not necessary given the traffic in the area served by the subject section (basically traffic generated by the parish and the exclusive subdivisions along the road). For one the section being widened from the intersection with the Antipolo Circumferential Road leads to a dead-end (i.e,, the gate of an exclusive subdivision). And so, traffic is generally very light along this road section
Are there plans to revive the original right of way of the old railway line but in the form of a road connecting Hinulugang Taktak to Ortigas Avenue via Valley Golf? If not, then the road widening of Daang Bakal is unnecessary. Even if the justification were for cyclists, I would argue that perhaps you only needed to have paved shoulders that need not have the same width as the carriageway lane. Following are photos of Daang Bakal featuring the road widening project.
From the photos, it is clear that a lot of trees have been cut in order to make space for the additional lanes for the road. While most of these trees are too close to the original carriageway, there were many that I felt didn’t need to be cut if a narrow shoulder was deemed sufficient for the road. Traffic in the photos are typical peak period traffic on a Sunday when the road carries the most traffic in a day due mainly to churchgoers.

Roadworks along Sumulong Highway, Antipolo City
The roadworks along Sumulong Highway continues with drainage work along the sections across Palos Verdes and Cavalier’s Village. They have cleared a lot of trees along the road’s edge on the Masinag-bound side and only one lane is usable for these sections. This has recently caused several road crashes involving all types of vehicles. While there are obvious shortcomings about the worksite on the contractor’s side, many hardheaded drivers and riders continue to operate their vehicles (read: drive or ride recklessly) as if there are no hazards along the road.
Concrete culverts line the Masinag-bound side of Sumulong Highway
Worksite occupies one lane of the 4-lane/2-way highway. Temporary barriers often encroach upon the single lane available to Masina-bound traffic. This leads to many vehicles encroaching on the opposing traffic lane, violating the double line that states “no overtaking.” Perhaps the contractor needs a refresher or a lesson in proper traffic management and signage for worksites?
Completed sections are not immediately cleared, apparently and likely to have proper curing for the concrete. Notice in the photo that the project includes sidewalk construction. Sidewalks will enhance safety for pedestrians and even joggers or hikers going up and down Antipolo.
Notices are nailed to many trees that will be cut down to give way to highway drainage and sidewalks along the Antipolo-bound side of Sumulong Highway.

Throwback to 1995 – Baguio flyover
Baguio retains a special place in me as it is where I did my first out of town project back in 1995. This was just after I finished my master’s at UP Diliman. The project was Baguio’s first flyover or overpass and it was being proposed along Bokawkan Road, which is then as now a very busy thoroughfare connecting the city to La Trinidad, the capital town of Benguet province. Our task was to determine the best configuration for the flyover including the required capacity for it and the remain at-grade roads once it was built.
I remember it was very rainy when we were there and our accommodations (which was volunteered by our client – their family’s vacation house in the city) turned out to be quite inhospitable. We had to buy blankets and make our own beds as we had practically no budget to stay at a hotel. I recall the house was a bit creepy especially for the last few days I stayed there by myself (my mentor had to go back to Manila) to supervise the traffic surveys at the proposed site of the flyover. That was quite the adventure for me then as I also tried to explore the city on foot. I walked the entire stretch of Session Road when it was still the Session Road (old) people reminisce about. I also walked around neighborhoods in the Gen. Luna area where the house I was staying at was located.
Here are some photos of the flyover now and the area where I supervised traffic surveys together with the bridge engineer who was from Baguio.
The flyover as seen from one of the side streets in the Trancoville district.
A closer look at this almost 20-year structure.
Traveling along the service road along the flyover and towards the direction of La Trinidad. Shown also in the photo is one of the pedestrian overpasses in the city. I actually like the architecture of these overpasses that seems more apt compared to Metro Manila’s steel structures.
I included this photo past the overpass to show how crowded Baguio is already with houses having replaced trees in many mountains and hills. These used to be all green with trees back in the 1990s with only a few shanties that had started to sprout back then. I have other photos of such scenes of houses growing out of the mountains around the city and will share those in another post soon. Such have become the representation of unsustainable development for a city that has become overcrowded and yet continue to attract many people who eventually become residents.

Pinagmisahan Street, Antipolo City
A couple of weeks ago, traffic had to be rerouted from a section of the city’s Circumferential Road (also known as the Sen. Lorenzo Sumulong Memorial Circle) between the intersection with Taktak Road and Pinagmisahan Street to Pinagmisahan Street. This was due to the preventive maintenance work that had to be done to the pavement. As such travelers including myself had to use Pinagmisahan to travel between Sumulong Highway and Ortigas Ave. Extension. It was not my first time along Pinagmisahan but it was my first to traverse the road from end to end. Following are photos showing sections of Pinagmisahan Street from the Clinica Antipolo end to the Daang Bakal end (i.e., northbound).
Pinagmisahan Street on the left with ‘No Entry’ signs for the Circumferential Road section being maintained.
On a typical weekday, there are many school service vehicles parked along the road. Many of these are for the Montessori school across from Clinica Antipolo, which does not have sufficient parking for vehicles it attracts.
Pinagmisahan used to be a narrow 2-lane road. It has been expanded recently into a 4-lane road with Portland Cement Concrete Pavement (PCCP).
While the expansion included the construction of sidewalks, many electric posts remain in their original positions and pose safety hazards to motorists.
White Cross, which is a popular destination during the Lenten Season and especially during the Holy Week is accessible via this road.
There appears to be many informal settlers living in communities along the road. They have encroached on the RROW and hamper the completion of the expansion of the road.
I think this part of the road is practically the highest in terms of elevation. There should be a good view of the surrounding areas including the city center and Hinulugang Taktak from this area.
Another section of Pinagmisahan showing informal settlers
Curved downward section towards Daang Bakal and Taktak Road – the fence on the left is for Fairmont Subdivision.

I’m featuring Pinagmisahan here as I thought its timely given a lot of people will be using it this Holy Week to go to White Cross, which has life-size images for the Stations of the Cross.

The benefits of walking
I came across an old article on walking that appeared in The New Yorker in 2014. This was after reading another article my wife shared that also was about walking. One is about both the physical and intellectual benefits of walking while the other was about walking without a purpose. Both were about walking and thinking, and definitely about the benefits of even a short stroll to our physical and mental being.
Here’s the article from The New Yorker: Why walking helps us think
And the article from BBC: The slow death of purposeless walking
I highly recommend both articles as we ponder about making our cities safe for pedestrians/walking.

Some interesting (and required) readings on traffic engineering
Christmas breaks allow me to catch up on a lot of reading. The previous months comprising our university’s semester were spent preparing for lectures though I had to do some readings related to researches I am involved in. Browsing the net and social media, I came across 2 articles shared by an acquaintance. He is a very progressive planner who has extensively studied and written about the most relevant issues in urban planning, focusing on transport. A third article I found while reading one of the two. These were very interesting for me in part because they are thought provoking in as far as traffic engineering is concerned.
- What traffic engineers can learn from doctors
- As traffic deaths rise, blame engineering dogma
- The new science of traffic engineering
The author seems to call out traffic engineers in general but these articles should also be contextualized properly. The situations mentioned in the articles are to be found in cities in the United States and may not be applicable in other cities in other countries. Traffic engineers in Europe, for example, have been working on exactly the solutions being mentioned in the articles that would make streets inclusive and safe especially for pedestrians and cyclists. The same with Asian cities like Singapore and Tokyo.
In the Philippines, however, there is so much that we can learn from the articles. The mere mention of the design guidelines being used in the US betrays the flaws of highway and traffic engineering in the Philippines. The Philippines’ highway planning manual and other guidelines used by the Department of Public Works and Highways (DPWH) are heavily drawn from US references. Most highway and traffic engineers in the country are educated using curricula that use US textbooks and references. There are even civil engineering programs that use licensure exam review materials as their references! These exam materials are also known to be based on DPWH guidelines and manuals aside from problems “outsourced” or patterned after the Professional Engineer (PE) exams in the US. Few schools have progressive curricula that look to best practices that take into account the complexities of roads especially in the urban setting. Such ‘copying’ of American standards and practices in many cases do not consider Philippine (local) conditions and blind applications to our roads instead of proper adaptation often have lead to unsafe and inequitable roads.

Caught (up) in traffic
