根据所有者Crossrail Ltd.（CRL）的数据，伦敦陷入困境的Crossrail项目由于Covid-19的造成了延误，并推动了超过240亿美元的成本。

The project’s December 2019 completion target was pushed back late last year to summer 2021. That deadline has now slipped again, to the first half of 2022. At the same time, CRL forecasts an additional funding requirement of $1.4 billion in addition to the $2.8 billion increase it secured in December 2018.

Sponsored jointly by Transport for London and the Department for Transport Crossrail’s “Elizabeth line” will link upgraded networks on either side of the city with 21 km of new twin tunnels through the city center.

Crossrail的首席执行官Mark Wild说：“伊丽莎白线的交付现在处于复杂的最终阶段，并且由于进一步的共同爆发的风险和潜在影响，在不确定性的情况下完成。”

CRL将最新的延误归因于轴，门户和10个中央部分站的工作中计划的生产力，这受到大流行造成的劳动力限制的加剧。

“Londoners will accept that COVID-19 has played a significant role in this delay, and that the complexity of this project and the need to complete the work safely have meant it’s had to be pushed back yet again,” says Alison Moore, London Assembly Member and chair of the London Assembly Transport Committee. “Lessons must be learned from the way Crossrail officials originally planned for this major infrastructure project.”

Crossrail’s budget was set at $20.8 billion when the government approved construction in 2007. A period of value engineering in 2010 reduced that figure to $19.4 billion, partly by pushing back the completion target from May 2018 to December 2019. The budget went up to $23.1 billion in 2018.
