All Traffic Conditions
Live map for all 13 expressways
SLEX experiences moderate to heavy traffic daily, particularly in the Magallanes-Alabang section. The northbound morning rush and southbound evening rush create consistent congestion. Weekend traffic to Tagaytay and Laguna adds additional volume.
SLEX is one of the busiest expressways in the Philippines, carrying daily commuter traffic between Metro Manila's southern suburbs and Laguna/Batangas.
The Magallanes-Bicutan section is consistently congested during rush hours due to its proximity to the Makati CBD. The Bicutan-Alabang stretch also sees heavy traffic as it serves the Muntinlupa residential area.
The Alabang-San Pedro section has improved since CALAX opened, diverting some Cavite-bound traffic. Beyond Sta. Rosa, traffic is typically light except during weekends when Tagaytay-bound and Nuvali visitors create moderate southbound flow.
Friday evening southbound traffic to Batangas (for island ferries) and Laguna (province return) is notably heavy.
SLEX is divided into three distinct traffic zones. The northern section from Magallanes to Alabang (13 km) is the most congested, carrying dense commuter traffic from Muntinlupa and Parañaque. The Bicutan interchange is a major bottleneck where Skyway and SLEX traffic merge.
The middle section from Alabang to Sta. Rosa (18 km) improved after CALAX opened, diverting Cavite-bound traffic. The San Pedro and Biñan exits still see moderate rush-hour congestion from residential communities.
The southern section from Sta. Rosa to Calamba (25 km) is typically clear except on weekends when Tagaytay-bound travelers (exiting at Mamplasan/CALAX) and Batangas-bound travelers (continuing to STAR Tollway) create moderate southbound flow. The Calamba interchange connecting to STAR Tollway handles the transition smoothly.
