Malaysia–Singapore Second Link is a bridge connecting Singapore and Johor, Malaysia. In Singapore, it is officially known as the Tuas Second Link. The bridge was built to reduce the traffic congestion at the Johor–Singapore Causeway, and was opened to traffic on 2 January 1998. The twin-deck bridge supports a dual-three lane carriageway linking Kampong Ladang at Tanjung Kupang, Johor to Jalan Ahmad Ibrahim at Tuas, Singapore. The total length of the bridge over water is 1,920 m (6,300 ft).
At Malaysian side, the bridge is connected to the Second Link Expressway (E3) also known as Linkedua Expressway, which links from Senai North Interchange (exit 253) at North-South Expressway, Senai Airport and Taman Perling, Johor Bahru via its extension known as Johor Bahru Parkway. In Singapore, the bridge connects to the Ayer Rajah Expressway.
Usually, traveling along the second link is much faster than traveling on the Causeway, as the traffic is smoother in both directions. However, during festive periods (especially Chinese New Year, Hari Raya, Christmas and Deepavali), the huge amount of traffic going between Malaysia and Singapore still leads to massive jams on both the causeway and the second link.The Malaysia-Singapore Second Crossing heralded a new era in bilateral relations, and brought with it the promise of improved economic and social ties.
