The Metro Rail Transit Line 4, also known as MRT Line 4, is an approved monorail rapid transit line to be built in Metro Manila and Rizal in the Philippines.^[3] When completed, it will be the first monorail line in the Philippines and the second rapid transit line serving the province of Rizal after the extension of LRT Line 2 to Antipolo, and will significantly reduce the volume of vehicular traffic along Ortigas Avenue and improve connectivity in the eastern parts of the metropolis, including the nearby municipalities in southwestern Rizal.

The proposal, consisting of eleven stations, will have a right-of-way alignment along N. Domingo, Ortigas Avenue and Taytay Diversion Road,^[4] linking suburban Taytay, Rizal to the Ortigas Center business district in eastern Metro Manila.^[4]

The project costed an estimated ₱59.3 billion or US$1.1 billion.^[4][5] According to the Department of Finance, the Philippine government is looking to fund the construction through the Asian Infrastructure Investment Bank and the Asian Development Bank.^[6]

History[]

The first MRT Line 4 project was proposed in 1999 as a line between Recto Avenue, Manila and Batasan Hills, Quezon City. In the late 2010s, the proposed line was renumbered as the MRT Line 8.^[7]

A new LRT Line 4 project,^[4] was approved by the Investment Coordination Committee (ICC) of the National Economic and Development Authority in June 2015 as a public–private partnership project,^[8] with construction slated to begin in 2017 and a targeted opening date in 2021.^[4]

However, the initial project was not pushed through until it was approved for a second time on December 20, 2019.^[5] The contract for the architectural and engineering design of the project was signed by the Department of Transportation and Spanish design consultant IDOM Consulting Engineering, Architecture, SA on October 1, 2021. Construction is slated to begin by the second quarter of 2022 and targets to be operational by 2028.^{[3][9][10][11][12]}

Route[]

It will start from N. Domingo, one block away from Gilmore station of Line 2 at Quezon City in the west, to SM City Taytay in Dolores, Taytay in the east, passing through the cities of Mandaluyong and Pasig and the municipality of Cainta. An empty lot beside the Taytay Municipal Hall and Manila Club East Resort had been reserved for the depot.^[13]

The 2019 proposal reduces the line from 18.4 km (11.4 mi) to 15.56 km (9.67 mi) and it will consist of 11 stations, plus 2 stations that could be built for future demand.^[11]

Alignment between Ortigas Center and LRT-2[]

The line is a component of the Manila East Rail Transit Project proposed by the Japanese government in February 2015 which aims to provide a medium-capacity rail transport system connecting central and eastern Metro Manila with the province of Rizal.^[13] Its proposed alignment is along Ortigas Avenue with an option to extend the line to as far east as the Rizal municipality of Angono on the Manila East Road, and west to either of the following terminals:

• Option 1: interchange with Santa Mesa station (PNR Metro South Commuter Line) via ADB Avenue, Sheridan Street, Pioneer Street, Boni Avenue, Aglipay Street and Lubiran Street.
• Option 2: interchange with V. Mapa station (LRT Line 2) via ADB Avenue, Shaw Boulevard, P. Sanchez Street and V. Mapa Street.
• Option 3: interchange with Gilmore station (LRT Line 2) via a straight path following Ortigas Avenue and Gilmore Avenue in San Juan and its western extension Granada Street in Quezon City.

Option 2 was the chosen alignment of the study owing to its capability to serve the most demand that can alleviate traffic the most on the Taytay-Cainta-Pasig-Mandaluyong-Manila corridor. Construction was not pushed through despite receiving approval by President Benigno Aquino III last September 2015.^[15]
