Late July and early August witnessed the Athens Tram and Light Rail become operational, and these two systems provided additional connections to those already existing between Athens and its waterfront communities along the Saronic Gulf. These communities included the port city of Piraeus, Agios Kosmas (site of the sailing venue), Helliniko (the site of the old international airport which now contained the fencing venue, the canoe/kayak slalom course, the 15,000-seat Helliniko Olympic Basketball Arena, and the softball and baseball stadia), and the Faliro Coastal Zone Olympic Complex (site of the taekwondo, handball, indoor volleyball, and beach volleyball venues, as well as the newly-reconstructed Karaiskaki Stadium for football). The upgrades to the Athens Ring Road were also delivered just in time, as were the expressway upgrades connecting Athens proper with peripheral areas such as Markopoulo (site of the shooting and equestrian venues), the newly constructed Eleftherios Venizelos International Airport, Schinias (site of the rowing venue), Maroussi (site of the OAKA), Parnitha (site of the Olympic Village), Galatsi (site of the rhythmic gymnastics and table tennis venue), and Vouliagmeni (site of the triathlon venue). The upgrades to the Athens Metro were also completed, and the new lines became operational by mid-summer.
