The proposal was to build a new underground transport interchange station that would optimise the connection with Metro lines 6 and 11 for close to 60,000 users of inter-urban buses, particularly once the latter line is extended to the city centre. This would result in the removal of street-level inter-urban bus services, complete the reorganisation programme of all the inter-urban bus terminals around the Circular Metro line and improve the waiting and bus-changing experiences of bus users.
