The Interstate Highway System was launched when President Dwight D. Eisenhower signed the Federal-Aid Highway Act of 1956. Its purpose was to provide high-speed, high-capacity system of highways without stoplights and with exits spaced, whenever possible, at least a mile apart.
The interstate highway system has had a profound effect upon the American economy and contributed significantly to improved economic efficiency and productivity. By increasing speed and expanding access, freight costs have been reduced substantially.
They were intended to serve several purposes: eliminate traffic congestion; replace what one highway advocate called “undesirable slum areas” with pristine ribbons of concrete; make coast-to-coast transportation more efficient; and make it easy to get out of big cities in case of an atomic attack.May 27, 2010

On the other hand, the nonliving things of this ecosystem are low in salinity due to the fact that the sea water, when it meets the river water, loses a large percentage of it, it also offers an ideal temperature for the proliferation of life.
Therefore, we can conclude that according to the article, an estuary is a coastal body of water where the mouth of a river meets the sea.
