Subject to approval, it is expected work could begin on site in 2025, with the station planned for opening by the end of 2027.
The new Merseyrail station is one of four planned by recently re-elected Liverpool City Region Mayor Steve Rotheram, who has committed to completing the project by the end of 2027 – a year ahead of its current schedule.
The other three new stations at Daresbury in Halton, Woodchurch on the Wirral and Carr Mill in St Helens, with work to develop all three underway by the end of the decade.
Steve Rotheram, Mayor of the Liverpool City Region, said: “There are some unique challenges with the design of the site given that the station platform is subterranean.
“However, these plans for Liverpool Baltic further demonstrate our ambitions for the future of public transport in our area – a modern, fully accessible network with state-of-the-art infrastructure that unlocks opportunities for people and businesses.”
Neil Grabham, managing director of Merseyrail, said: “This is an incredibly complex project, but the end result will be something that will make a massive difference – not just to the Liverpool Baltic area, but to the whole of the city region.
