The Erie Canal in New York is part of the east–west, cross-state route of the New York State Canal System (formerly known as the New York State Barge Canal). It was built to create a navigable water route from New York City and the Atlantic Ocean to the Great Lakes, originally stretching for 363 miles (584 km) from the Hudson River in Albany to Lake Erie in Buffalo. Completed in 1825, it was the second longest canal in the world (after the Grand Canal in China) and greatly enhanced the development and economy of the cities of New York, including Albany, Syracuse, Rochester, Buffalo, and New York City, as well as the United States.

Explanation:

a complex sentence consists of an independent clause and one or more dependent clauses.  

to write complex sentences, we must use subordinating conjunctions.  

all the complex sentences begin with a subordinating conjunction and when it occurs, a comma must be place at the end of the dependent clause. on the contrary, if the sentence begins with an independent clause, then no comma is used.
