Step-by-step explanation:
The first iron bridge ever built (1879) was located in central England, home of the Industrial Revolution. Major industrial cities such as Manchester and Birmingham brought together the labor, raw materials, and industry connections necessary to manufacture products during the Industrial Revolution. The port city of Liverpool gave access to the world markets established by Britain's extensive colonial empire. These colonies provided raw materials, new ideas, and cheap labor for the new industrial factories. Raw materials such as cotton, which did not grow well in Britain, became a major import that fueled the textile mills of the Industrial Revolution.
