Ministers are to take take a direct role in overseeing the building of the HS2 rail line to try to "get a grip" on the rising cost of the high speed route between London and Birmingham.
Transport Secretary Louise Haigh said it had long been clear that the cost of HS2, which could reach £65bn, had been allowed to "spiral out of control".
She said she had now seen "up close" the "scale of failure", which she described as "dire".
"I have promised to work fast and fix things and that's exactly why I have announced urgent measures to get a grip on HS2’s costs and ensure taxpayers’ money is put to good use," Haigh said.
The government also confirmed it will not reinstate previous plans to run the high-speed line to Crewe and Manchester, which were scrapped under the previous Conservative government.
A spokesperson for HS2 Ltd said: “We welcome the Secretary of State's priorities for HS2 Ltd and are committed to working with the new Government to improve delivery."
Adding: "HS2 Ltd recognises that there are many lessons to be learned from delivery to date and, under new leadership, are actively implementing the changes within our control to stablise costs."
A new independent review of the project has also been commissioned.
The government confirmed it has commissioned the review which will be carried our by a former Chief Executive of Crossrail, James Stewart.
HS2 Ltd said that it looks forward to the "recommendations" of Mr Stewart.
In January, the boss of HS2 Ltd estimated that the total cost of HS2 could rise, saying a hike in the cost of materials such as concrete and steel have added £8bn to £10bn to the project's budget.
