New York City, preparing for the flood of visitors expected for the Statue of Liberty centennial celebration, announced yesterday that it would close major arteries, open space for thousands of campers, put every possible bus and subway train into service and deploy an army of police officers during parts of the four-day July 4 weekend. The plans, detailed at a City Hall news conference, include closing the Brooklyn Bridge, the Brooklyn-Battery Tunnel, the Franklin D. Roosevelt Drive and the Henry Hudson Parkway during parts of the festivities. All of Manhattan south of Chambers Street is to be closed off for most of the weekend. The Police Department will set up a command post from which it will monitor - and redeploy, if necessary - the thousands of police officers who will be on the streets. The Transit Authority said it would put every possible bus and subway in service and run them at peak-hour schedules. And for the first time in its history, the Parks Department will open a park and two beach parking fields for camping and for recreational vehicles.

The Central Intelligence Agency has been told by Italian authorities that the sole terrorist survivor of an attack on the Rome airport has directly implicated Syria in his mission, according to American officials. According to the Americans, the terrorist, Mohammed Sarham, told his Italian captors that Syrian agents had trained him and accompanied him on his journey from the Bekaa region of Lebanon to Damascus through Belgrade, and then on to Rome. The American officials said that until the information about the Rome terrorists being trained in Syria reached President Reagan about two weeks ago, the United States had been operating in the belief that Mr. Sarham was acting under orders from Libya. Libyan Role Still Stressed Administration officials said that intelligence agencies still believed Libya was involved in both the Rome and Vienna airport raids on Dec. 27, but were coming around to the view that Syria played at least as big a role.

International A terrorist implicated Syria in the Rome airport attack last December, according to American officials. They said Mohammed Sarham, the sole surviving attacker, had told Italian authorities that Syrian agents had trained him and helped him get to Rome. [ Page A1, Column 3. ] Mohammed Abbas was in Algeria when he said in an American television interview that President Reagan had become ''enemy No. 1,'' according to American Government sources. Washington has complained to Algeria for not turning over the suspected terrorist to Italian or American authorities. [ A12:1-2. ]

The Securities and Exchange Commission yesterday delivered to Judge Richard Owen of Federal District Court in Manhattan the names of nine stocks on which it plans to build its insider trading case against Dennis B. Levine, a former Wall Street merger executive. The list, requested by Judge Owen after a hearing yesterday, seemed to suggest that the S.E.C. was conceding for the present that it had no evidence to show that Mr. Levine had engaged in illicit dealings in 54 separate stocks as originally charged. The list, delivered late yesterday, was not immediately available. It was understood to consist only of stocks in which the S.E.C. contends that Mr. Levine had a direct knowledge because he personally worked on takeover projects relating to them.
