The Niuzhaishan Tunnel, which stretches 1,697 meters, is an important part of the Jinjing Bay Boulevard. The double arc-tube tunnel will span four lanes in each direction.
Workers will put the final touches to the road surface and walls, reinforcing the rock faces with concrete, and installing cables and pipelines in the next stage.
The construction team had targeted a starting date for the tunnel some time in June.
After opening to traffic, the tunnel will save about 20 minutes for drivers who previously had to take a detour, according to a project manager.
