Zhangpu Chihu is planning to build a large passage to the coast, where to build it.

The highway engineering route from Huxi Town in Zhangpu County to the connecting line of the coastal large passage starts from the vicinity of Dingtan Village in Huxi County Road 5 19 and extends southward along County Road 5 19. Use the existing Zhangzhao Expressway Bridge to cross the expressway, pass through Xia Wei, Zhaojiacheng Village and Puqian Fruit Farm, and then route along the south side of Houhu Village, passing through Chishui, Wushiwei, Yangweishi and QianZhang Cun. Continue to extend southward through Xicheng Village and Xixie, and cross the longitudinal line (coastal passage) transversely. The end point is near the south side of Shayuan, and the route length is 13.0 1 km (where the route from K0+000 to K5+800 basically extends southward along the existing county road 5 19). The starting point of the branch line is connected with the county road 535 connected with the Zhaojiabao exit of Shenhai Expressway, and it is routed to the west side of the county road 535, passing through the north side of Tiancun and Lindong Village, and the end point intersects with the main line K2+290. Branch line length 1.6 18km. The total length of the road is 14.680km (including branch lines 1.6 18 km), and the estimated total investment of the project is 258,048,930 yuan.
