The government can take various steps to expedite the completion of projects that have been delayed by State governments. Some of these measures include:

• Ensuring that there is adequate funds allocated for the projects
• Appointing a task force or committee to oversee and monitor the progress of the project
• Using electronic tendering and payment systems that are transparent and efficient
• Implementing strict timelines and deadlines for the completion of each stage of the project
• Ensuring that staff responsible for the project are regularly trained to stay updated with new technology and skills
• Strengthening the legal framework and regulatory environment to deal with any disputes that may arise

Overall, all stakeholders, including the government, contractors, and State governments should work closely together to ensure that projects are completed in a timely and efficient manner, while ensuring quality standards are met. This will not only provide a boost to economic growth but will also enhance people's livelihoods by providing job opportunities and increasing income.
