The island of Java is densely populated and is the center of the Indonesian economy where 60% of the country's population resides and about 58% of GDP is produced on the island. The facts above clearly show that the concentration of population and economic activity on the island. The North Java road runs along the northern coastline of the island and extends in an east-west direction. The North Java road connects major industrial cities such as Jakarta, Surabaya, Semarang, etc. to each other and strongly supports the country's socio-economic and industrial activities. With the increase in traffic volume along Jalan Jawa Utara, transportation efficiency decreases rapidly due to traffic congestion that forms especially at intersections in urban parts, railway crossings and along urban sections where many street stalls are concentrated along the side of the road, which affects a healthy social life. economic and industrial development. To address the above problems, the Government of Indonesia (hereinafter referred to as the Government of Indonesia) has decided to build flyovers at six priority locations along the North Java Corridor to eliminate traffic congestion and to achieve smooth traffic. The project is called the North Java Corridor Flyover Project. The project was assessed by the Japan Bank for International Cooperation (hereinafter referred to as JBIC) and a loan agreement between the Government of Indonesia and JBIC implementing the Special Term for Economic Partnership (hereinafter STEP) was signed in March. that affect a healthy social life. economic and industrial development.

The construction of the Merak flyover began on October 14, 2009 with a 15-month construction period and a total financing of IDR 131 billion.
