How many bike lanes can you make with…?

December 2020


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:] 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”?
