The closure will enable demolition of the current station building and a new one to be built adjacent to it.
A recommended, temporary diversion route will be put in place for customers wanting to access the station via Wednesfield Road (see Type=media;MediaID=15262;Title=Station Acces map;Target=_blank;).
The station works will take place in 2 phases, with rail services continuing to operate as normal throughout.
The redevelopment of the railway station is expected to be completed in 2020 and forms part of the £150 million City of Wolverhampton Interchange improvements scheme.
The new layout means the pedestrian subway will bring customers directly into the heart of the station building, which it does not currently do.
Councillor John Reynolds, City of Wolverhampton, Cabinet Member for City Economy, said: "The closure of the pedestrian subway is essential to enable the demolition process to begin.
"The aim is to deliver a railway station befitting of the city - it is the next stage in delivering a £150 million transport hub to provide an attractive commercial gateway to those entering the city by national rail, bus or tram.
"There is £3.7 billion of investment currently on site or in the pipeline across the City of Wolverhampton.
"As part of this regeneration it is crucial visitors to our city get the best first impression possible and their travel experience is enhanced - the new state of the art station will deliver that."
Steve Parry, Managing Director Ion, added: "The temporary closure of the subway marks an important milestone in the development. It means we will be able to start the demolition process and begin the journey that will bring the city a state of the art railway station with superb transport links."
Richard Brooks, customer experience director at West Midlands Railway, said: "The work planned as part of the Wolverhampton Interchange project is going to transform public transport in the city, with new station facilities and better connections to the rest of the region at its heart.
"We're creating a railway that the West Midlands can be proud of and can call its own. Wolverhampton is an important station on our map. The redevelopment of the station shows the important role railways play in supporting the economic wellbeing of our region."
The first phase of full demolition will start in early July.
The British Transport Police building and a small section of the current station building next to Platform 1 will be demolished, paving the way for the first section of the new station building to be erected. It will become operational to customers by summer 2019, when phase 2 of the programme will also start.
The new station will be connected directly to a tram stop, once work is completed on the Midland Metro city centre extension. The Midland Metro Alliance are currently delivering the next phase on Pipers Row before continuing down Railway Drive to the railway station.
