Between the 1990s and the 2000s, traffic congestion was prevalent at the Sultan Ismail Bridge and Muar town centre since the official opening of the North–South Expressway Southern Route between Ayer Keroh and Pagoh and the opening of the Tangkak and Pagoh Interchange on 1 April 1989. To this end, in 1998, the federal government announced that the new second bridge would be built at Parit Bunga to ease congestion on the existing bridge. In addition, a new bypass linking Parit Bunga to Parit Sakai would be built.
