After 35 years of daily operations, battling the inclement weather and myriad of vibrations caused by up to 554 trips a day, multiple sections of LRT-1 have suffered from cracked concrete and exposed or damaged rebars. But today, private operator Light Rail Manila Corporation (LRMC) announced the completion of its structural restoration works for the parapets, river bridges, and faulty concrete of the existing 20 kilometer LRT-1 line.
LRT-1 has been here for 35 years. The project ensures that it will be here for the next 30.
“Today, LRT-1's parapets are new, stronger, and securely fastened to the viaducts,” LRMC President and CEO Juan F. Alfonso said. "The project completion strengthens our confidence in ensuring passenger safety."
The structural restoration project which was started in 2018 included repairs on the concrete surfaces of the parapets, sandblasting to remove corrosion, and repainting. “We also installed new collision dampers at certain pile caps to protect bridges from ship collision," Alfonso added.

Today, LRT-1's parapets are newer, stronger, and securely fastened to the viaducts.
The viaduct now has a continuous row of noise barriers running along its 20-km length. Situated in one of the most congested parts of the metropolis, with schools, apartments and offices nearby, the noise generated by running trains has been one of the most complained-about aspects of LRT-1. The noise barriers will now significantly mitigate excessive noise generated by train operations.

The collision bumper of river bridges near Pasig River were also replaced to protect the viaduct beam from collision with barge or flat-bottomed vessel transporting freight or passengers along the river.
"LRT-1 has been here for 35 years. The project ensures that it will be here for the next 30," said Alfonso.
