Congestion on both sides of Epifanio delos Santos, commonly known as EDSA, is an ordinary sight especially during rush hours. Even as buses are confined to the carousel lane, the Metro Manila Development Authority is doing all strategies to ease the flow. MMDA also believes that a factor is that the volume of private vehicles continues to increase by the day. EDSA, a 23.8-kilometer main thoroughfare, was constructed in 1940 to connect Metro Manila cities from Roxas Blvd in Pasay City the south to McArthur Highway in Caloocan in the north.
