The Epifanio de los Santos Avenue Busway, also known as the EDSA Busway and the EDSA Carousel, is a bus rapid transit system in Metro Manila, Philippines. Interim operations began on June 1, 2020 to augment MRT Line 3. Full operations began on July 1, 2020, when Metro Manila was placed under a general community quarantine. Intended to be largely served by bus stops along the median, some stops are temporarily served by bus stops on the curbside. The system runs on a dedicated bus lane which is separated by concrete barriers and steel bollards.
