ATLANTIC CITY, New Jersey (AP) -- A fourth Atlantic City casino is going out of business.
Trump Plaza will shut its doors at 6 a.m. (1000 GMT) Tuesday.
The casino at the center of the Boardwalk and the end of the Atlantic City Expressway has been declining for years, performing worse than any of the city's other casinos.
It joins the Atlantic Club, the Showboat and Revel, each of which has closed this year.
And the contraction might not yet be over: Trump Plaza's parent company is threatening to close its sister casino, the Trump Taj Mahal, in November.
The closings are mainly due to growing competition in nearby states in the saturated northeastern U.S. gambling market.
Atlantic City began the year with 12 casinos; by Tuesday morning, it will have eight.
