An open truck is carrying the Shiv Sena chief's body and there will be a three-tier security around it - the Mumbai Police will make up the first layer, the Rapid Action Force (RAF) will be the second tier and Shiv Sena volunteers will make up the third.
The procession was to start at 7 am, but was delayed as roads around Matoshree were filled with thousands of supporters. Bal Thackeray's body was finally brought out of his house a little after 9 am. His son, Uddhav, broke down just before the body was loaded onto the truck.
Security has been beefed up across Maharashtra, particularly in Mumbai, where 48,000 policemen have been deployed to keep vigil ahead of the funeral today. No autorickshaws and taxis will ply in Mumbai today; the Mumbai transport service has arranged for extra buses.

Today, at every 100 metres along the route of the funeral procession, 25 policemen have been deployed. The police has issued a traffic advisory and suggested that people stay home, unless absolutely necessary. "I appeal to people to remain calm and maintain law and order," Mumbai Police Commissioner Satyapal Singh said.
A senior policeman at the Maharashtra Police Headquarters here, said, "The entire police force is on alert in Maharashtra. Lakhs of people are expected to visit Mumbai to get a last glimpse of Thackeray."
Along the procession route alone, around 20,000 cops, 15 companies of State Reserve Police Force and three contingents of the Rapid Action Force have been deployed. The Police Commissioner said he had cancelled his daughter's wedding reception party on Sunday since he would be busy.

Taxis and autorickshaws will remain off the roads today, their associations said here. There will be no cab and autorickshaw services from the city airports - domestic and international - either. BEST has decided to operate extra buses to facilitate travel for the last rites of the Sena leader. The Central Railway has also cancelled the megablocks on Central and Harbour line services tomorrow for the same purpose.
Mumbai has been calm till now, although most shops and other establishments - especially in the Sena stronghold of Dadar - began to close down as news of Mr Thackeray's death came in. There were reports of shop being closed in Colaba and other Mumbai suburbs too and auto-rickshaw and cab drivers in many places reportedly refused to travel across the city for fear of violence or possible vandalism by Shiv Sena workers.
So much of the city wore a deserted look on Saturday evening with shops, hotels, restaurants and other commercial establishments were closed and there was sparse traffic on the streets. "We did not ask anybody to keep their shops shut. People are doing it voluntarily," the police commissioner said.
