Yeah, the Vyttila and Kundannoor flyovers are only in the planning stage. But the government are promising to complete these two projects quickly. These two flyovers will also be 6 lane flyovers and they will be around 800 metres long. Both the flyovers will be very useful for both the areas, especially Vytilla, with the Metro also coming nearby. There are plans to build the Metro over the Vytilla flyover. But, the traffic which is already very high in these areas will increase because of the construction work on these flyovers. These flyovers will hopefully ease traffic in the city once they are built.
Actually, work hasn't begun on the Palarivattom flyover, they've only laid the foundation stone as of now. The flyover will be constructed on the Palarivattom bypass junction, and will be 620 metres long. This project is part of the Speed Kerala project that was initiated by the Kerala government and the government has said that it will cost 72 crore to build the project. From June 5th onwards they will issue tenders for the building of the Vyttila and Kundannoor flyovers. After this according to the detailed project report, they will finalise the date for the laying of the foundation stone.
