The management of the South Luzon Expressway (SLEX) appeals to motorists for more patience and understanding due to the traffic congestion caused by the skyway extension project. Traffic buildup on SLEX usually starts at 5:30 A.M. Additional traffic enforcers are deployed to supervise passing vehicles and the counterflow on the southbound lane of San Pedro heading to Amkor Anam. The SLEX administration also advises the public to plan trips well and allot two to three hours lead time.
