Is it permissible to dig a well in a public thoroughfare for the benefit of Muslims or the road itself?

Primary text

If digging a well is intended for the benefit of Muslims, such as providing water for passersby or draining rainwater from the road, the permissibility depends on the road's condition. If the road is narrow, or if digging it obstructs the path, causing fear of people or animals falling in, or narrowing their passage, it is not permitted because the harm outweighs the benefit.
