Updates on the MRT Line 7 construction

I recently posted some photos showing the progress of work on the Line 2 Extension. This time, I wanted to show photos on the progress of the Line 7 construction along Commonwealth Avenue. Following are some photos my companion took this morning as we headed for Novaliches. Work continues along this major corridor even on Sundays. While it has caused much congestions and therefore inconvenience, the continuous work offers hope to those who will benefit from this mass transit line once it becomes operational.

Columns rise along Commonwealth Avenue just across from the Ever mall and St. Peter’s church.

Here’s a traveler’s view of the ongoing construction along Commonwealth Avenue.

Concreting even on Sundays – it was quite congested today near the Fairview Market due to lanes occupied by heavy equipment including several concrete mixers lined up along one lane to supply the mix.

I have several former students who are now working on the Line 7 construction in various capacities. I usually get my updates from them. I am happy for them to be involved in such a major infrastructure undertaking. Hopefully, their experiences will be useful for other future railway lines in the country.

Some updates on the Line 2 Extension

I just wanted to post a couple of photos showing the progress of the Line 2 Extension construction work. There are two stations along the extension including the future end station before the Masinag Junction (intersection of Marcos Highway and Sumulong Highway).

Ongoing construction of the Line 2 Masinag Station just across from SM City Masinag in Antipolo City, Rizal – there are actually 3 usable lanes with only the middle being a full lane, the other two have concrete barriers encroaching along the site as shown in the photo.

Ongoing construction of the Emerald Station across from both the Sta. Lucia and Robinsons Metro East malls at the boundaries of Pasig City, Marikina City and Cainta – the construction site here is longer than the one for Masinag but has wider spaces for traffic. Volumes, however, are significantly heavier than at Masinag so this area can easily become congested with traffic often stretching past the PLDT  office along the westbound side and Ligaya along the eastbound side.

I will post more about the progress of construction for these stations in the future especially as it would be interesting to see the actual forms of the stations.

Progress of C-6 expansion and upgrading

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.

Another look at the San Juanico Bridge

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.

Article on the need for ‘Context Cities’

Here is another good article I’ve found and read recently:

Wolfe, C.R. (2017) “Forget ‘Smart’ – We Need ‘Context Cities'”. (Last accessed: 12/21/2017).

Much has been said, I believe, about smart cities. I, too, have attended and even spoke (about Intelligent Transport Systems) at conferences or fora that had ‘smart cities’ as the central theme. Most talk about how technology can be used to further development and to address various transport and traffic problems. A lot of people tend to be excited when technology gets into the mix of things and yet few seem to be interested in a city seeking its true identity. And so the concept of ‘context cities’ over ‘smart cities’ become important as we need to contextualise what a city should be before we conclude that a technology push is the way to leapfrog into advancement. Perhaps the soul can be found and reconciled with and this is done through the context and not tech, which cannot replace history, heritage and culture that are distinct attributes of each city.

The newly opened 2nd Barkadahan Bridge

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.
