Skegness and Grantham police stations are due to reopen from next week.
Both buildings have been shut since March because of the coronavirus pandemic.
Lincolnshire Police say they've introduced safety measures to ensure social distancing rules are observed.
Lincoln South Park and Boston Police Stations have remained open during the Covid-19 crisis.
Lincolnshire Police says its "101" non-emergency number is currently not working.
The force says it's a national problem.
The 999 emergency number is, however, not affected:
More officers will be on the roads in Lincolnshire in an effort to make the highways safer, the county's police force has promised.
Special constables and volunteers will also be enlisted to help educate drivers or enforce legislation, according to the force's new road policing plan.
The creation of a dashcam hub for people to send in footage of incidents and poor driving is in the final stages, the force adds.
We are investing in roads policing officers as part of the uplift of additional officers in our county. Our officers, special constables and volunteers will all be working hard to educate or enforce road traffic legislation. I invite our communities to read this plan and to work with us to keep our roads safer."
The Chief Constable of Lincolnshire Police, Bill Skelly, has announced he's to retire.
After 31 years in policing he says he'll step down from his role on 18 December.
Born on the east coast of Scotland, Mr Skelly joined Lincolnshire Police from Devon and Cornwall.
Through his policing career he has held many positions, including leading the Immigration Crime Team at New Scotland Yard and being appointed in 2008 by Her Majesty the Queen as her Inspector of Constabulary for Scotland.
Mr Skelly says though there have been "many challenges", it's been "a privilege and an honour" to lead the Lincolnshire force.
What I’ve seen is a workforce who constantly rise up and respond to any difficulties put in their path. I am proud to have been among colleagues who come into work day in and day out, determined to make a difference and improve the lives of others wherever they can."
Lincolnshire's Police and Crime Commissioner, Marc Jones, said Mr Skelly cared "passionately for the welfare of those in his charge".
He added: "Bill has left Lincolnshire Police a very different force to the one he joined in 2017 and it's no exaggeration to say that his mark will be felt for years to come."
Police are appealing for help identifying this man and locating his next of kin after he was found dead in Boston:
The man's body was found on Sibsey Road on the evening of 20 March.
His death isn't being treated as suspicious and a file has been prepared for the coroner, according to Lincolnshire Police.
However, officers say they still haven't been able to identify the man despite "extensive inquiries" so can't notify his family of his death.
Police say he was known as Mariusz Krawczyk, but officers are "unsure if this is his true identity".
He's in his 30s and has a "distinctive" tattoo on the top of his left arm depicting a skull being held in a hand, police add.
Anyone with information about the man's identity is being asked to contact the Lincolnshire force.
