The mass transit project was initially planned from Surjani Town to M.A. Jinnah Road. However, the route has now been amended and will pass through Burns Road, Pakistan Chowk and then from Sindh Secretariat to Merewether Tower.
The new design of the route has been approved by engineers and experts working on the project.
Apart from this, the clock tower at Cantonment Board Office roundabout will be dismantled and a new tower will be built instead. The cost will be borne by the federal government.
There will also be an increase in the number of buses and bus stops and the capacity of passengers after the construction of the Green Line metro system.
The extension is likely to cause a 9 percent increase in the project which costs an estimated 16 billion rupees.
The project was initially approved from Surjani Town to Gurumandir. It was extended to Merewether Tower upon its inauguration by Prime Minister Nawaz Sharif.
