Project Overview
1. The main content of this project is to reconstruct the East Road in a sunken manner.
2. The East Road underpass tunnel project has a road reconstruction length of about 1.63km, of which the total length of the tunnel is 1217m (780m of buried section, 239m of newly built open section, and 198m of reconstructed open section). It starts from the planned North Second Ring Road in the north, goes under the south continuously, and ends at Zhongyi Road. The main urban road is 50km/h, the planned red line width of the standard road section is 40m, the main line tunnel has two-way lanes, and the open section is equipped with four two-way auxiliary lanes.
3. The tunnel of this project is a city traffic tunnel that does not allow chemical hazardous vehicles to pass. It is a Class III tunnel. There is a reverse slope section at the junction of the tunnel start and end and the road subgrade section. Rainwater from the road subgrade section will not be discharged into the tunnel. This project is a supporting project for the East Road Tunnel. Tunnel drainage needs to be implemented simultaneously with the road project and the tunnel.
