The Alabang Viaduct is currently being rehabilitated. There's an expected build-up of traffic at the southbound lane from Sucat to Alabang. Please add 30 minutes lead time to your usual travel time going south.
Also, after Sucat, we advise you to take the rightmost lane in order to avoid the traffic buildup of vehicles crossing the viaduct.
For those coming from the north area (specifically Quezon City thereabouts), please leave at 7 or 730pm.
