The road is point about north-south and street is point about east-west,I think.

about 街 : In China ,there are many cities and towns The road in these places,we can call the “路” is a “街". We also call a “路”is a "街". But “路” has many meanings ,such as "the Silk Road"，that means the road from one place to another. In the cities,we can also say for example" 人民路" or 人民街. And another example is ," Do you know the way(路) to my new school？in this place ,we should use "路".

街 = street 路 = road

really thanks!

街 has the direction of north-south while 路 has the direction of west-east but it depends on where u r..... for some cities, its just like this but for others, its the contrary so u can say: there is no difference...... it is just used for the street or the road.
