There are 10 expressways, most of them ends with E (stands for
expressway) like KJE (Kranji Expressway), CTE (Central Expressway)
and PIE (not the pie you eat but Pan-Island Expressway) except for
one special expressway called ECP (East Coast Parkway), maybe due
to the fact it has a E in front (or it becomes ECE) or maybe
because it just runs along the East Coast Park.
