Origin of the Name
Using the names of the starting point Busan and the end point Paju, the road was called the “Busan ~ Paju Line.” The number of the north-south bound road was given the odd number 77. Originally, the expressway was called the “Busan ~ Incheon Line” ending in Dong-gu, Incheon Metropolitan City, but after Jayu-ro was included at the end of 2008, the destination changed from Dong-gu, Incheon to Munsan-eup, Paju-si in Gyeonggi province. Subsequently, the name was changed to the “Busan ~ Paju Line”.
