Greater Cambridgeshire hears from academic that underground transport can be cheaper option - report

A Cambridge University professor has told a meeting of the Greater Cambridge Partnership that building underground transport could work out cheaper than overground alternatives, Cambridge News has reported.

Professor John Miles told the representatives that putting transport on land in a city such as Cambridge is expensive. According to the report, he said: "If you deliberately keep the tunnels very small, and on the top you have a very congested urban space, then these things work to reverse the equation, and it can work out cheaper than going over the top."

Cambridgeshire and Peterborough Mayor's James Palmer concurred, the newspaper said.
