Refer to the poll on the right of the page link above.
The Question:
How do you feel about driving underground for a continuous stretch
of 9 kilometres in the Kallang/ Paya Lebar Expressway? CTE has two
stretches that are underground, and they total 2.4 km only.
a) I do not think driving underground is an issue. It should be the
same as driving on an open expressway at ground level.
b) Ill feel anxious since I do not know what to expect. After all,
KPE will be the longest underground tunnel in South East
Asia.
c) As long as there is clear signage and sufficient directions
before and in the tunnel, I think it should be alright.
Note: I do not work for LTA.
