The total length of National Freeway No. 7 is approximately 23 km. It has nine ramps or interchanges, which are Nansingduan, Linyuan, Linhai, Dapingding, Siaogang, Daliao System, Fongliao, Niaosong, and Renwu System. The overall expenditure is about NT$61.55 billion.
The construction of National Freeway No. 7 will increase the capacity of the north-south transport corridor in Kaohsiung, bringing in the following five benefits: a complete freeway/highway network on the east side of the metropolitan area of Kaohsiung, dispersion of vehicle traffic on National Freeway No. 1, enhanced access from the port area, available service for traffic along the freeway, and facilitated local operation and development of industries. Regarding the environmental impact assessment instructions for this project, the Environmental Protection Administration convened an environmental impact assessment and review committee meeting on August 30, 2013, during which a resolution was reached to proceed to the second-phase environmental impact assessment. The environmental impact assessment report is expected to be ratified in December 2016.
The opinions of local people will continue to be drawn through presentations, coordination meetings, interviews, and other channels.
On June 17, 2014, the Taiwan Area National Expressway Engineering Bureau convened an interdepartmental consultative meeting on National Freeway No. 7. The Ministry of Transportation and Communications invited the Ministry of Economic Affairs, National Development Council, city government, and relevant authorities to set up a promotion team and a work group to continue promoting the construction of National Freeway No. 7.
