Niger declares state of emergency on roads

I think there may be some confusion here. Niger is a landlocked country in West Africa, and it's not possible for a country to declare a state of emergency on roads, as roads are a physical infrastructure and not a political entity.

However, it's possible that you may be referring to a situation where the government of Niger has declared a state of emergency in response to a crisis or issue affecting the country's transportation infrastructure, such as a major accident, a natural disaster, or a security threat.

If that's the case, I'd be happy to help you find more information on the specific situation. Could you please provide more context or clarify what you're referring to?
