Upgrade details on Trichy Airport is very skethcy to come by. We all know that there is an upgrade effort that is going on and is supposed to complete by the end of 2007. But what exactly  is the e work that is going on is not very clear. I found this PIB from Govt Of India which throws some light on the work that is going on in Trichy and Madurai airports.

Excerpts from this PIB on Trichy Airport:

At Tiruchirappalli airport, the works relating to extension and strengthening of runway, construction of isolation bay and new fire station and construction of new terminal building with all modern facilities including two aerobridges along with expansion of the apron and link taxiway have been taken.
