Another group aims to hold a brief demonstration along Jalan Sultan to pressure the government to preserve heritage buildings earmarked to make way for the MRT (Mass Rail Transit) project.
The crowd at Jalan Sultan are expected to join Gabungan Janji at about 10pm.
Meanwhile, about 25km away in Shah Alam, the Selangor government is hosting its own countdown event at Dataran Kemerdekaan.
9pm: Dataran Merdeka - People are begin to trickle in, gathering in front of the iconic Sultan Abdul Samad building. There is a slight drizzle, possibly keeping others at bay.
