This is my design I made from Tinkercad. What you should see is a bridge and two tunnels. Why? Because the Waka Kotahi (NZ Transport Agency) has a chance to use these designs.
The reason why I did this is because Auckland NEEDS A NEW BRIDGE. Traffic has been a big problem on roads. Alternative ideas include the tunnel I did, on the right of the road tunnels will also be a railway. and railways mean new stations in the North Shore. It’s not finished but I will today or this week. The bridge design will be a second bridge left of the current harbour bridge.
