Someone in a social media group subscribe to posted about the future Bataan – Cavite interlink bridge that will cost 175.7 Billion Pesos for 32.15 kilometers (~5.465B PHP per km). That’s a lot of money but is understandable for a major infrastructure project that will required much state of the art engineering and construction for its implementation. I casually mentioned that it was a nice project but belongs to those I’d classify as “nice to have but not really necessary or urgent at this time.” Others were more direct in saying it was another “car-oriented” project. The price tag is quite hefty and a similar amount could have been used for other, more urgent projects around the country that could benefit more people than this bridge. So for the sake of discussion, let’s try to estimate how much of another project can we make out of the estimated cost for such a bridge.
Perhaps among the more popular items due to the pandemic are infrastructure and facilities for active transportation (i.e., walking and cycling). Many cities have initiated projects that encourage more walking and cycling in order to promote healthier lifestyles as well as to reduce car dependence. The Federal Highway Administration (FHWA) of the US estimates that bike lanes can be developed for $5,000 to $50,000 per mile depending on various factors and conditions. That’s 150,000PHP to 1.5M PHP per kilometer at 48PHP : 1 USD. [Ref: https://safety.fhwa.dot.gov/saferjourney1/library/countermeasures/10.htm] Using these numbers we can easily estimate how many kilometers of bike lanes we can produce for 175.7 B pesos. That simple division exercise will give us from 117 thousand (at 1.5M/km) to 1.171 million (at 150k/km) kilometers of bike lanes. For comparison, the Philippine national highway network is 32,932 kilometers. The numbers could mean bike lanes could laid out for the entire national road network with much to spare for provincial, city and municipal roads for connectivity. Funds can even be allocated to improve pedestrian facilities! This begs the question then of how such resources can be used in a more comprehensive manner to benefit a lot more people. From the bragging point of view, won’t such a bike lane network be more impressive than one bridge?
What else can you think about that can be funded by amounts similar to the Bataan – Cavite Bridge or other projects you can tag as “nice to have but not really necessary or urgent”?
This is a continuation of the feature on the aftermath of Typhoon Ulysses (Vamco). I am posting this here as part of my archives on the floods in the Marikina Valley.
There’s a road branching off from Marcos Highway that links to a bridge crossing the Marikina River and connects with the FVR Road along the Marikina Riverbanks. The following photos speak for themselves in as far as the mud and garbage that was left after the floods subsided.
Descending from Marcos Highway, only one of two lanes are passable after heavy equipment moved tons of mud and garbage to the roadsides. The fences trapped a lot of garbage, too, as seen in the photo.
Piles of mud and garbage at the service road leading to the east bank of the Marikina River and the SM Marikina access road.
Under the Marcos Highway Bridge, garbage, mostly plastics, remain on the wire fences. This area was totally submerged during the height of the floods with water reaching the underside of the bridge. Fortunately, the bridge seems undamaged.
Even lamp posts and electric poles caught a lot of garbage.
The Olandes housing development was surely affected by the swelling of the river.
The FVR Road leading to C-5 is already clear for 2-lane traffic but you can see the mud and garbage all around. The dried mud has turned into dust (alikabok) that blows away as vehicles pass through the road. There is also mud on the plants in the median planters as this area was also submerged during the height of the typhoon.
Here are more photos of the situation in the vicinity of Barkadahan Bridge. Photos were taken on a late Sunday morning (around 11 AM). Photos show the traffic congestion particularly along the eastbound side of Ejercito Avenue and Barkadahan Bridge.
Even before completely crossing the bridge, one can see how long the queue from C-6 is. This is a photo of the queue just past the West Bank Road. The road here is names Ejercito Avenue after former Pres. Joseph Estrada whose real family name is Ejercito.
Truck occupying an entire lane and encroaching on one of the lanes to C-6. This is due to the bottleneck caused by the wall of a residential subdivision across from the Greenwoods gate. The wall actually only contains the subdivision name and yet DPWH has been unable to expropriate the land that includes part of that subdivision’s driveway.
Long queue extending towards Tapayan Bridge along Ejercito Avenue
Queue along Tapayan Bridge or bridges considering there are two – one for each direction of traffic.
Queue crossing the bridge and the bend towards C-6 and Lupang Arenda, which is a major relocation site for Metro Manila squatters during the time of then Pres. Joseph Estrada. Vehicles turn left towards C-6 while those going straight continue along Ejercito Avenue towards Pinagbuhatan, Pasig City.
The queue reaches C-6 on a Sunday morning. It is likely worse on weekdays.
I recently wrote about the Barkadahan Bridge and its current state and compared it to the Marcos Highway Bridge that is now completed and fully opened to travelers. Unfortunately, I didn’t have photos to share but only shared my observations based on what friends have told me and what I’ve read on social media (i.e., Rizal Provincial’s and Taytay’s official Facebook pages) about the situation there. I finally had the opportunity last Sunday when I went to fetch my family at the airport. Here are photos of the Barkadahan Bride and its environs. Note that Barkadahan is actually two bridges and not one. The new one is currently being used for two way traffic (one lane each) while the second one is under rehabilitation and retrofitting. The latter had and will have 2 lanes, too.
Approach to the Barkadahan Bridge via Highway 2000 – notice the widening on the south side of the highway? That’s the ROW expropriated to align the bridge(s) with the highway. Ultimately, this should be of the same width as C-6.
Closer to the bridge, you see more of the ROW acquired to improve the geometry for the area and the intersection with the East Bank Road. Highway 2000 is now aligned with the second (newer) bridge constructed that will eventually carry only the eastbound traffic. The older bridge currently being rehabilitated and retrofitted will carry the westbound traffic.
Vehicles crowd on the two-lane bridge that is the new Barkadahan Bridge. The old one is currently being rehabbed. Notice the significant volume of trucks using the bridge? This is expected to increase due to the industrial developments in Rizal Province and along C-6, and the direct route this corridor provides towards the SLEX via Bicutan.
Big sign at the bridge – there are many of these scattered around Pasig and Rizal advising travelers against using the route and Barkadahan Bridge because for the construction work on the bridge. This ‘avoidance’ basically transferred (some say returned) much of the traffic to Ortigas Avenue Extension. Many if not most users of the bridge use this alternate route to travel from Rizal to BGC and Makati CBD.
A peek at the construction work on the old bridge – note that the contractor seems to have completed installing the steel reinforcement for the slabs for this section of the bridge. The next phase would be the concrete pouring.
Still another peek showing the extent of the work on the old bridge – my casual observation of the work areas was that there seems to be not so many workers. But then maybe it was a Sunday? Perhaps there should be more people working considering this is a very urgent project?
Tricycles, motorcycles and bicycles – there’s a lot of local traffic using the bridge and these are represented by mostly tricycles serving the residential and commercial areas along the East and West Bank Roads and the cyclists you most often see crossing the bridge. Most motorcycles are through traffic. On weekends one can observe more recreational cyclists as this route is a popular one to Rizal and particularly its mountainous areas that are popular to mountain and road cyclists.
Counterflow – many motorcyclists tend to counterflow and this adds to the friction and slows down traffic. Once the other bridge is completed and re-opened, these will likely be reduced to lane splitting or filtering as the opposite flows of traffic will be assigned to separate bridges. Counterflow traffic will then be very obvious and should be apprehended.
Here’s the resulting queue on the other side of the bridge. This is severe congestion that reaches C-6. Note that the photo was taken on a Sunday. Perhaps these travelers have no other option but to use this route so they are stuck in hellish traffic on a Sunday? I can only imagine how worse it is on weekdays.
As a parting shot, I think there are still a couple of things that need to be addressed once the bridges are both open to traffic:
- Optimizing traffic management at the intersections with the East Bank Road and West Bank Road of Manggahan Floodway – the (mis)management of traffic here also contributes to congestion in the area. Traffic enforcers on both ends of the bridge have basic knowledge of how traffic must be managed and end up with the “buhos” approach. They don’t seem to be coordinating with each other, too. Their approach also heavily favors the East and West Bank roads when traffic is heavier along the main corridor that is C-6/Highway 2000. There needs to be a more efficient way to manage traffic here and that may be in the form of a sophisticated traffic signal system at least for the two intersections. Settings need to be studied and signals have to be adaptive to the variation of traffic throughout the day.
- Resolve bottlenecks in the area including structures that tend to reduce capacities of the approaches to the bridge.
More on this topic soon!
The Marcos Highway Bridge was scheduled for rehabilitation in the next four months starting last week. While it will not be totally closed to traffic, the scheme reducing its capacity will surely lead to congestion along Marcos Highway. This congestion should be expected along other roads as well, as travellers, particularly those taking private transport will be using alternative routes in order to avoid this area. Those coming from the east will likely go through Marikina City via the parallel route comprised of Sumulong Highway and A. Bonifacio Avenue. Others will turn to A. Rodriguez (Ligaya). And perhaps others may go via Ortigas Avenue Extension. These alternative routes correspond to the other bridges crossing the Marikina River connecting the Rizal province and part of Marikina and Pasig to Metro Manila.

I will write more on this topic once I get more information on what’s happening to the traffic in the area. Meanwhile, I do know that my usual alternative route via Marikina and Tumana seems to have more than the usual traffic during my commute. While it is easy to attribute this to the partial closure of the Marcos Highway bridge, this could also be just a normal variation in the typical daily traffic for that route.
This is a continuation of the series of posts about my recent trip to Bicol where I was able to take some photos for items I generally label. These stock of photos are posted here for several reasons including convenience of access in case I need them for lectures or other presentations. Previously, I had posted on vertical curves along the Andaya Highway. This time around are some photos I took of railway bridges along the PNR’s Main Line South and particularly in Camarines Sur. It was quite challenging to look for or anticipate seeing these structures; many of which are quite old and in a state needing urgent maintenance. Most if not all are steel truss bridges and the ones in better conditions are shown in the following photos. All were taken within the Naga City boundaries.
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.
View of the steel truss footbridge that goes underneath the Tandang Sora flyover
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.
I’m currently in the Netherlands and after fulfilling my responsibilities here, I decided to go on a trip to Arnhem. Arnhem was the site of one of the more memorable events during World War 2 when the British 1st Airborne attempted to take the Arnhem Bridge as part of Operation Market Garden. The drama that unfolded is told in the movie “A Bridge Too Far” where Arnhem was the titular bridge that was to be taken and held by the British. However, only Lt. Col. John Frost’s 2nd Parachute Battalion made it to the bridge and had to defend it against a superior German force.

Airborne at the Bridge is kind of a museum with video retellings of the events pertaining to the bridge. It includes material of Operation Market Garden, which was a massive land and air operation that was supposed to lead to an end of the war in Europe before Christmas 1944. They also have a shop selling literature about Market Garden and the events of the bridge as well as souvenirs.
A memorial to Jacob Groenewoud who helped gather intelligence for the allies during the operations to take the bridge. He gave his life to this cause, falling after being shot by a German sniper.
Airborne Memorial – an old artillery piece is set-up as if targeting the bridge. This was the side the British held until defeated by the Germans after what was a costly battle. The British lacked supplies as ground forces that were to relieve them were delayed at other bridges before Arnhem.

There is a plaque and memorial on the bridge retelling what transpired there in September 1944.

I had thought about going to Arnhem during this trip in The Netherlands. I am a military history buff and would have regretted it much if I wasn’t able to go to this site of one of the more dramatic events during World War 2. I picked up a few souvenirs at the memorial shop and will remember this experience quite fondly.
We have an ongoing project with the City of Tacloban and recently we went around the northern part of the city where many relocation sites were established after the onslaught of Typhoon Yolanda (Haiyan). After doing our fieldwork, we decided to cross the San Juanico Bridge into Samar island where we were told there’s a nice restaurant sitting atop a hill in the town of Sta. Rita.
Despite the rains, we managed to get some photos of the breathtaking views. Among these were this photo of the bridge as seen from Samar. Leyte and Tacloban are behind the bridge.
It is said that the part of the bridge on the Samar side has that distinctive ‘S’ shape while the Leyte side is a simple ‘L’ form. Trucks are weighed before they get on the bridge and the DPWH maintains a weigh station for this purpose before the Samar end. I didnt notice any from the Leyte side. Perhaps this is because most loaded trucks come via Samar rather that from Leyte?
Traffic along the San Juanico is usually light. This is despite the route being part of the eastern spine or nautical highway that is also part of the Asian Highway network. This leads me to suspect that similar (but longer and more expensive) bridges proposed for connecting other islands are unnecessary and cannot be justified when compared with other more urgent infrastructure projects including those that wil address urban congestion and promote improved mobility. The latter are more urgent and meaningful than massive structures that fewer people will use and benefit from.
A new bridge had been under construction beside the older Barkadahan Bridge. Instead of expanding the existing bridge, the proponents decided to build another bridge likely so as to reduce disturbance of traffic along the already congested first bridge. This is the same strategy for the bridge across the Pasig River in Nagpayong/Napindan that will reduce the potential bottleneck for when C-6’s expansion is completed. Unfortunately, the bridges don’t seem to include provisions for exclusive bicycle lanes that are clearly incorporated along much of C-6.
I took this photo as we were in queue at the approach to the intersection of Highway 2000 and the Manggagan Floodway’s East Bank Road. The new bridge can be seen here bearing eastbound traffic. The alignment at the intersection has not been addressed and so requires through traffic to basically swerve towards the entry to Highway 2000.
Here’s the intersection and the newly opened bridge. Note the vehicles coming towards my position as they follow a trajectory from the bridge to the narrow exit leg of Highway 2000.
Instead of a single lane along each direction, the two bridges now allow for at least 2 lanes of traffic either way. I say at least because a case can be made for 3 lanes to be indicated (there are no lane markings yet). The issue here though is that there is significant truck traffic crossing the bridge and two trucks traveling beside each other easily occupies the entire bridge. Thus, maybe a wide two lanes can be designated for both bridges with an opportunistic third lane forming depending on the traffic.
