Work on a shared cycle and footpath from Beck Lane in South Hykeham to Mill Lane in North Hykeham begins later this month.
As previously reported, the route will offer a safer way for children to get to school, as well as for commuters and leisure cyclists.
The work will take place during the summer holidays from July 21, and should be completed by September 3.
Through the six week period, a section of Mill Lane and Beck Lane will be closed, with local diversion routes in place via Boundary Lane, Newark Road and Moor Lane, with access for properties and businesses.
Funeral services at Mill Lane cemetery will also be unaffected.
The £130,000 project is funded through the county council’s Access LN6 programme.
Councillor Richard Davies, executive member for highways and transportation, said: “Many of the parents we spoke to in South Hykeham were concerned about how narrow the footpath on Mill Lane/Beck Lane was, and felt it presented a particular risk to young cyclists.
“These improvements will make it much safer for children to travel to-and-from school, and in the long-term it’ll hopefully encourage more young people to use their bikes to keep fit and healthy.”
