North South Corridor

 It cost $7.47 billion SGD to build the North South Corridor (21.5 km) in Singapore. This works out to $347 million per km.

The Boring Company (under Elon Musk) is able to build a tunnel for one lane of vehicle at a cost of $10 million USD per mile. This works out to $21 million SGD per km.

The North South corridor probably has 3 lines of traffic on each side. This is the equivalent to four Boring tunnels. 

The cost of 6 tunnels of 21.5 km using the approach of the Boring Company would be $21.5 X 6 X $21 = $2.7 billion SGD. This is 36% of the $7.47 billion that is spent.

It will also take a shorter time to build the four tunnels using the Boring Company approach

Here are some information of the tunnels built by The Boring Company

I know that there are big differences between the two types of tunnels. The comparison may not be reliable. We probably have to consider other costs and technical aspects. 

But, as a rule of thumb, the approach adopted by The Boring Company seem to reduce the cost by 64%.
