The free bus will allow residents to continue to access shops and local amenities while the essential bridge work takes place.
To complete the Great North Rail Project work safely, Church Road has been closed at the railway bridge until Sunday 30 June.
The shuttle bus travels on the diversion route from one side of the bridge to the other via Banks Road and Speke Road.
Joel Farrell, scheme project manager for Network Rail, said: “Work to reconstruct Church Road bridge is now underway and is vital to ensure it will remain safe and viable for years to come.
“To deliver our work safely, we have to close the road beneath the bridge while the existing structure is dismantled and replaced.
“We have listened to residents in Garston and from Wednesday, we will introduce an extended shuttle bus timetable to help keep people moving. I’d like to thank the local community for their patience.”
Each shuttle bus has a total capacity of 22 (15 seated and 7 standing) and is also accessible for wheelchair users and those with prams.
There is currently a shuttle bus operating between 7am and 8pm.
From Wednesday 10 April, shuttle buses will be more frequent and running hours will be extended to operate between 6am and 10pm:
- Between 6am – 7am buses will run every 30 minutes
- Between 7am – 8pm buses will run every 15 minutes
- Between 8pm – 10pm buses will run every 30 minutes
