Firefighters in Sheffield are gearing up to move into two new stations this summer.
One station is under construction off The Parkway, near the Mosborough turn-off and a second is being built at Birley.
They will replace the aging Mansfield Road, Darnall and Mosborough stations, which fire chiefs claim are costing money and are now in the wrong locations because of new housing developments springing up elsewhere in the city.
Fire chiefs have set aside £7.6 million to pay for the construction work.
They plan to sell off the three older stations to re-coup some of their costs and claim they will save money long-term by running fewer stations and more efficient buildings.
Some residents raised concerns over the closure of existing stations, fearing a delay in answering 999 calls in some communities.
But fire chiefs claim the new stations are needed because of housing developments around Crystal Peaks and the new Waverley development on the Sheffield and Rotherham border, which will see around 4,000 homes built over 20 years on the former Orgreave mining site.
They say Darnall fire station was originally built to be close to steelworks in the area, which are no longer there.
A spokesman for South Yorkshire Fire and Rescue said: “The new fire stations will enable us to provide a better service to the community, particularly to the south east Sheffield area.
“They will enable us to better protect the new housing developments in the area, which have been built in the last 20 years, the new Waverley development and the road traffic collisions we attend on The Parkway and nearby road infrastructure.
“The new full-time station at Birley Moor will cover a much greater area of South Yorkshire than the existing part-time station at Mosborough, right on the Derbyshire border, is able to.
“We will close the stations at Darnall, Mansfield Road and Mosborough, which are over 50 years old and were built to address risks that existed then, such as the steelworks.”
Maltby fire station in Rotherham is due to close next June when firefighters move into the nearby police station.
A government grant has been awarded to pay for the building work needed to convert part of the station to accommodate an engine and crew.
