Underground Space

Over the years, we have been making good progress in tapping underground spaces, from utility lines to rail lines and roads, to meet the many and growing needs of our urban environment. There are also extensive underground pedestrian links in areas like Marina Bay, which enhance connectivity and allow people to walk in comfort.

As evident in many urban cities, the use of underground space has largely been developed on a first-come-first-served basis. Over time, this hinders further expansion and optimal use of underground space.

By planning and safeguarding the space upfront and with the help of technology, we can unlock the potential of underground space and make better use of it.
