Kallang
The following expressways pass through Kallang:KPE consists of a 9 kilometres-long tunnel, which is the longest subterranean road tunnel in Southeast Asia. During its construction, the KPE tunnel was the world's sixth longest underground road project. Originally envisioned as two separate expressways, the 2.8 kilometres-long Kallang Expressway (KLE) and the 9.2 kilometres-long Paya Lebar Expressway (PLE), they were officially combined into one in 1991. Plans to build the KLE surfaced as early as 1981, and would have become the shortest expressway in Singapore if it was not merged into the KPE.
