1. Understand relevant laws and regulations: First of all, you need to understand relevant laws and regulations, especially the provisions on highway construction and house expropriation. This can help you understand your rights and obligations and the legal actions you can take.
2. Contact the local government: Contact the local government and express your concerns and opinions to them. The government may consider taking some measures to protect your rights and interests, such as providing economic compensation or relocation plans.
3. Seek professional advice: You can seek professional advice, such as architects, lawyers or land surveyors. They can help you assess the impact on your house and provide suggestions and solutions.
4. Participate in public consultation: If the government provides opportunities for public consultation, you can actively participate. This will enable you to better understand the expansion plan and express your opinions and suggestions.
5. Seek legal aid: If you think your rights and interests have been violated, you can seek legal aid, such as filing a lawsuit with the local court or the government.
In a word, in the face of the problem that the national highway expansion is too close to your home, you need to take active actions to understand your rights and obligations and take appropriate measures to protect your interests.
