Pasig River Expressway (PAREX) is a proposed megaproject in Metro Manila that includes building a six-lane skyway over Pasig River. Over the past few months; architects, urban planners, and environmentalists alike have united in disapproving the project due to how damaging, ineffective, inefficient, and unprepossessing it is to our environment and city. It is often and crucially cited how this expressway will kill the ecosystem in Pasig River; how it will induce more people to buy cars, hence heavier traffic; how it will make the land value in Metro Manila less; as well as how it will devastate the view of numerous heritage sites in the city. Currently, PAREX is approved for construction by the government, and progress in building it will skyrocket soon enough without legal action.
