A new shared footway and cycle path will be constructed on Station Road in North Hykeham this autumn.
The works, which will include street lighting and bus stop provisions, are expected to take four months.
Throughout the duration of the scheme, a one-way traffic management system will be in place, with cars being directed north from Freeman Road to Whisby Road.
All traffic from Freeman Road to Newark Road will remain two-way. The diversion route will be via Whisby Road, Doddington Road, Tritton Road and Newark Road.
Following a six month walking and cycling audit in 2013, Station Road was identified as a key area for improvement.
The road currently has a narrow footway and cycle path on the east side.
Lincolnshire County Council have proposed, through the Access LN6 programme, to install a new kerbed 2.5m wide path on the west side of the road.
The path will span from Hykeham Train Station to Whisby Road. Further improvements include renewal of the street lighting system, bus stop provisions and minor carriageway maintenance works.
The county council are seeking to ensure that the works coincide with carriageway alterations required as part of the new Persimmon housing development on Station Road.
An official start date will be set once a contractor has been appointed for the works.
