lack of a dedicated pedestrian walkway on the new access road, pedestrians are officially no longer allowed to cross the Causeway on foot, though it is tolerated during severe traffic congestion. JB Sentral railway station is the main railway station of Johor Bahru since 21 October 2010, replacing the old Johor Bahru railway station. JB Sentral also serves as the southbound exit immigration and customs checkpoint for rail passengers heading toward Singapore. Woodlands Checkpoint The new Woodlands Checkpoint, built partially on reclaimed land, was opened in 1999 to accommodate the increasing traffic flow and the soot which had enveloped the old customs complex over the years. The old customs complex, built in the early 1970s, at the junction between Woodlands Road and Woodlands Centre Road closed after the new checkpoint was opened in July 1999, although the motorcycle lane remained opened in the morning until 2001, and it had been reopened on 1 March 2008 for goods vehicles only. The new checkpoint complex also houses the Woodlands Train Checkpoint, opened on 1 August 1998, as the Singapore railway border clearance facility, which was previously co-located with Malaysian immigration and customs at Tanjong Pagar railway station. The relocation to Woodlands caused disputes between the two countries, which was resolved in 2010. On 1 July 2011, Woodlands Train Checkpoint replaced Tanjong Pagar railway station as Singapore's inter-city railway station. Northbound rail passengers pass through co-located border clearance for both countries at Woodlands Train Checkpoint before boarding the train to Malaysia. Southbound rail passengers clear Malaysian exit controls at JB Sentral, and Singapore immigration and customs on arrival at Woodlands Train Checkpoint. Attempts to have the causeway replaced As far back as 1966, there were several calls by the Malaysians to remove the Causeway. In 1966, in the Johor state legislative council, the speaker said that the Causeway was "more a hindrance than anything else" while a port should be built close to Johor Bahru to rejuvenate the city's economy. The state of Johor currently already has developed ports including Pasir Gudang and Tanjong Pelapas. The second demand came in year 1986 when Israeli President Chaim Herzog visited Singapore. At that time, the Singapore Government was criticised by Malaysian politicians and the press for allowing his visit. Under the former Mahathir administration, the Malaysian government scheduled to build a new customs, immigration and quarantine complex on a hilltop near the Johor Bahru railway
