Some two million Hindu devotees and visitors are expected to throng Batu Caves for the annual Thaipusam celebration on Feb 5.
Gombak district police chief Zainal Mohamed Mohamed said traffic congestion around Batu Caves is expected to continue until Feb 6.
He said the chariot procession will leave the temple in Jalan Tun HS Lee at around 10pm on Friday and arrive at Batu Caves at around 3pm on Saturday.
Seven roads around the Batu Caves temple will be closed from midnight today until Feb 8.
"The seven roads are the Kampung Melayu Batu Caves traffic light junction, the Middle Ring Road 2 turn-off to the Batu Caves Temple and the traffic light junction in front of the Shell Batu Caves petrol station," he said at a press conference in Kuala Lumpur yesterday.
"The other roads are the Jalan SBC 8/Jalan Lama Batu Caves junction, the Middle Ring Road 2 turn-off from Sri Gombak headed to the Jalan Perusahaan Batu Caves, and Jalan Perusahaan toward the Batu Caves Temple."
Zainal said the alternative routes proposed by the police would be updated on the Gombak IPD Facebook page.
"Road users are advised to use alternative roads and public transport to avoid traffic jams," he said.
