Police took away about a dozen protesters after warning people not to interfere with workers and bailiffs enforcing the court order to remove obstructions from the site, one of three that activists have occupied for nearly two months.
Protesters initially put up no resistance as workers in white hard hats and gloves tore down barricades, moving wooden pallets and other junk into the middle of an intersection to be taken away in a truck that had pulled up.
Pro-democracy lawmaker Leung Kwok-hung was among those taken away by officers to waiting police vans.
Traffic on the previously occupied section of Argyle Street which had been blocked by the protesters for nearly two months was flowing in one of the four lanes by late afternoon.
Protesters have been camped out on major thoroughfares in three areas of Hong Kong since September 28 demanding greater democracy in the semiautonomous city. The standoff has continued with no end in sight as neither the government nor the student-led protesters have shown any willingness to compromise.
A crowd of people supporting the police clearance operation applauded from the sidelines.
Businessman Andrew Tang said he traveled across Victoria Harbor to watch the barricade removal. He said the protesters were not realistic in their demands to China's communist rulers in Beijing and miscalculated by not withdrawing earlier.
"The Communist Party will never surrender," he said as he gave a thumbs-up to the police.
