What's the reason behind changing a road name? Frankly I can't think of any good reason really. In my opinion, roads, once named, should not be changed at all, unless the road is so physically different due to reconstruction maybe. Lately, the name change from Jalan Alor to Jalan Kejora baffles many Kuala Lumpur folk- what's the real reason behind this, only DBKL knows.
Here's a list of prominent roads in KL which have undergone name changes:
