The underground Woodlands Regional Bus Interchange hasn't seen any major renovation for eons, and you just know that if you stayed there for more than a couple of hours you'd either choke (because it gets so musty sometimes) or contract some pulmonary problems (due to all the bus exhaust).
Bless the interchange for having all the buses we need to get anywhere around the island, but honestly it does need some sprucing up. After standing strong and solid for 20 years, the interchange will finally see a proper refurbishment that the Land Transport Authority (LTA) says will be completed by 2019.
