I departed southern illinois airport for harrisburg-raleigh airport. Williamson county regional is almost in line with the route of flight and its tower has been closed for a few years. It has been common practice to monitor the CTAF while flying through the control zone, which is what I did. When I was almost out of the control zone I found out the tower was in operation and proceeded to my destination. The factors contributing to this occurrence were: no mention of a tower even existing in the current airport/facility directory, just a CTAF frequency given in the a/FD, no mention at all about a resumption of tower operations, no need to call FSS before the flight because I had flown the route before and I knew the weather was very good VFR. What really caused the problem was a lack of adequate up-to-date dissemination of information. I also assumed the tower would still be closed because it had been for a long time.

Title: AN SMA UNAUTH PENETRATION OF AIRSPACE.
Narrative: I DEPARTED SOUTHERN ILLINOIS AIRPORT FOR HARRISBURG-RALEIGH AIRPORT. WILLIAMSON COUNTY REGIONAL IS ALMOST IN LINE WITH THE ROUTE OF FLIGHT AND ITS TWR HAS BEEN CLOSED FOR A FEW YEARS. IT HAS BEEN COMMON PRACTICE TO MONITOR THE CTAF WHILE FLYING THROUGH THE CONTROL ZONE, WHICH IS WHAT I DID. WHEN I WAS ALMOST OUT OF THE CONTROL ZONE I FOUND OUT THE TWR WAS IN OPERATION AND PROCEEDED TO MY DEST. THE FACTORS CONTRIBUTING TO THIS OCCURRENCE WERE: NO MENTION OF A TWR EVEN EXISTING IN THE CURRENT AIRPORT/FACILITY DIRECTORY, JUST A CTAF FREQUENCY GIVEN IN THE A/FD, NO MENTION AT ALL ABOUT A RESUMPTION OF TWR OPERATIONS, NO NEED TO CALL FSS BEFORE THE FLIGHT BECAUSE I HAD FLOWN THE ROUTE BEFORE AND I KNEW THE WEATHER WAS VERY GOOD VFR. WHAT REALLY CAUSED THE PROBLEM WAS A LACK OF ADEQUATE UP-TO-DATE DISSEMINATION OF INFORMATION. I ALSO ASSUMED THE TWR WOULD STILL BE CLOSED BECAUSE IT HAD BEEN FOR A LONG TIME.
