Clashes between protesters and police left at least 188 officers and about a dozen demonstrators hurt, said officials, after a small group stormed a tunnel which was part of the work site at Chiomonte, west of Turin.
Scuffles between protesters and a heavy police presence continued throughout the day on Sunday with a steady exchange of tear gas, stones and molotov cocktails.
Police arrested at least five people and Italy's President Giorgio Napolitano condemned the violence. Police blamed the trouble on hundreds of masked
leftist "black block" extremists from Italy and neighbouring countries.
Protest organisers said tens of thousands of demonstrators had gathered peacefully from surrounding regions to stop the construction of the planned tunnel in the Susa valley.
But a small band broke away from the main group of protestors to enter the gated work site guarded by hundreds of police, who put the number of demonstrators at about 6,000.
The project, agreed by Italy and France in 2001, would slice three hours off the current seven-hour train journey between Paris and Milan.
In a statement, President Napolitano condemned what he said was the work of groups "trained in illegal violence."
He was joined by Prime Minister Silvio Berlusconi and figures across the political spectrum.
Police were out in force on Sunday as authorities had expected more trouble from radical groups within the protest movement after similar clashes last week.
Twenty-five policemen and four protestors were slightly injured on June 27 when a demonstration at the same spot turned violent and police responded with tear gas.
Before Sunday's events, the leader of the "No Tav" (No to the high-speed train) movement, Alberto Perino, said that demonstrators would have "bare hands and clean hands against those whose hands are neither bare nor clean".
Work on the main 58-kilometre tunnel, of which 12 kilometres are in Italy, is scheduled to begin in 2013 and due to go into service around 2023.
