Warrington is to go into Tier 3 lockdown on Tuesday - 48 hours earlier than expected.
The measures have been moved forward following talks between the council and government.
Council leader Russ Bowden said it was the 'necessary and proportionate thing to do'.
The restrictions, which will see pubs close unless they're serving 'substantial' meals and a ban on household mixing, will come into force at 12.01am on Tuesday.
Casinos, betting shops and soft play areas will also close and residents will be advised against travelling outside the area.
Gyms, leisure centres and hairdressers can remain open.
Warrington's infection rate is currently 354 cases per 100,000 people, compared to the national average of 190.
Some 15 people have died in Warrington Hospital with coronavirus in the last three days.
Coun Bowden said: "We know that our case numbers in Warrington remain stubbornly high, but what is more concerning is the number of admissions into hospital.
"The upsetting and grim reality is that there are more people in hospital, more people in intensive care beds and more people being taken by the virus, and we need to do all we can to try to bring this under control.
"Moving into tier 3 is one of many important steps we need to take as a town to try and reduce transmission of the virus.
"Please keep doing all you can to play your part: wash your hands, keep your distance from others not in your household, wear a cloth face covering and if you have any symptoms, however mild, self-isolate and get tested immediately.
"We need to act together, and now, to protect our elderly and vulnerable loved ones, and to support our hospital and their staff who are doing a tremendous job."
The council has been given £5.9m to support the extra restrictions, with £1.68 million allocated to public health and£4.2 million to be used for business and employment support.
