According to Sir Jonathan Thompson, over the previous few years, the cost of materials like steel and concrete has increased, adding between £8 and £10 billion. The government canceled the portions that connected Manchester, the East Midlands, and the West Midlands in October. On the expense of constructing the remaining portion, HS2 Ltd. and the government are at odds. According to the business, the cost of the London-Birmingham stretch in 2019 would range from £49 billion to £56.6 billion. According to the government, it should be delivered for between £45 billion and £54 billion. These approximations were assembled prior to the announcement in October. But Sir Jonathan doesn’t think £45 billion is feasible. Although he expressed doubts, he claimed the cost might be less if taxpayer money wasn’t used to build a new station at Euston.
