The new, upcoming bus services will double the number of buses between Wigan and the Trafford Centre.
This marks a major milestone for Greater Manchester's Bee Network.
Greater Manchester took back control of its bus network a year ago, aiming to give local communities more input into the operation of bus services.
The 132 service connecting Wigan with the Trafford Centre will run every 30 minutes, doubling its previous frequency.
Also, the new 615 service will connect Wigan with Middlebrook retail park, restoring a link that was lost four years ago.
The changes come after a detailed review of service performance across Greater Manchester's bus network, made possible by the introduction of franchising.
This allows Transport for Greater Manchester (TfGM) to ensure services meet the Bee Network’s customer commitments.
Mayor of Greater Manchester, Andy Burnham, said: "The introduction of the first new Bee Network bus service is an important milestone.
"Once again, we are proving the benefits of a locally controlled and accountable bus network by delivering improvements for our local communities.
"The only way we can grow the Bee Network, improve services and keep fares low is if more people use it, so I’d encourage everyone to get onboard and enjoy our cleaner, cheaper and more reliable bus service."
The service improvements were introduced in response to community feedback.
Transport Commissioner for Greater Manchester, Vernon Everitt, said: "We have listened to feedback from the local community and I am delighted that we are moving quickly to introduce the first new Bee Network service connecting Wigan with Middlebrook and doubling the frequency of a key commuter and leisure route from Wigan to the Trafford Centre."
Nigel Featham, managing director of Go North West, highlighted the role of the 615 service in supporting local transport.
He said: "The introduction of the 615 is a fantastic example of how franchising can deliver real benefits to passengers by providing the services they need, when they need them most.
"As we head into the busy festive season, these changes will make it easier for people to access major retail and leisure destinations, while also improving connectivity across Greater Manchester."
Passengers are encouraged to check any changes to their normal service by visiting a Travelshop or checking the Bee Network app or website.
Information will also be updated on bus stops.
Councillor David Molyneux MBE, leader of Wigan Council, said: "With the new 615 service restoring a previously scrapped route and more buses running from our borough to the Trafford Centre, these first 12 months have seen some great improvements in our local network."
