The orange line is the line going from Poonamallee to Lighthouse ( via Vadapalani ). Current estimates given by the government say that the project is expected to be complete by December 2025. How much delay ( in years ) will it be, before it opens for public ?

Specifics:

• Fully operational means the entire line. So if a part of the line is opened for public, it will not be counted.

• If the line's plan ( route, number of stops etc. ) is changed, this question will resolve to N/A.
