Skyway is no longer a bus zone starting February 16, 2020. San Miguel Corporation (SMC) has implemented a new traffic scheme in order to reduce the volume and size of vehicles passing through the elevated expressway. Only class 1 vehicles will be allowed, and class 2 and 3 vehicles will have to use the at-grade section at the appropriate toll gate entry points.
Buses and delivery vans and trucks should take other routes. If coming from Makati, Manila, and Pasay on the way to Alabang, The Nichols southbound toll plaza should be used for entry. From NAIA expressway, class 2 and 3 vehicles must take Andrews Avenue going to Sales Road, and subsequently, Nichols southbound entry toll plaza to the at-grade Skyway. Magallanes northbound off-ramp can also be used by buses and delivery vans from NAIA Expressway to make a U-turn under the Magallanes interchange then head to the Nichols southbound toll plaza.
The new traffic scheme was implemented because of the construction being done to extend and connect Skyway to the South Luzon Expressway (SLEX) in Susana Heights exit, and Muntinlupa-Cavite Expressway (MCX). A three-lane elevated northbound section and two-lane elevated southbound section will be in place to make it easier for motorists to travel to and from Manila and the south.
