Construction of a median or entry island is much like that of a pedestrian island. However, there is no provision for pedestrian crossing with a median island or an entry island. Also, their width and length, for the most part, follow their intended purpose, and not a particular standard size. They may also be designed for landscaping. With an NTMP project a few years ago, I designed a unique pair of two-level median islands which were landscaped by the local residents and were much liked (No.4)
