A cycle way is to be developed between North Ballachulish to Corran Ferry.
The first phase of construction is due to get underway on Monday.
The £1million investment from transport agencies Sustrans and Hitrans will connect the existing cycle way in North Ballachulish to the popular Corran Ferry terminal in Nether Lochaber.
The improvements will see the existing footway that runs alongside the A82 Inverness to Glasgow road upgraded to provide a new 3.6 mile long cycle way through a phased programme of works over the next six months.
The existing footway will be widened, where practical, to 8.2ft and resurfaced to provide a smoother and safer journey for cyclists as well as providing better access for pedestrians. A new cycle bridge will be installed across the River Righ as part of the improvements.
The works will begin on Monday with the first phase being between the River Righ and the ferry access. The rolling programme will see all phases of the improvements scheduled to be completed in the spring ahead of the busy tourist season.
To allow construction of the first phase to take place safely, temporary traffic lights will be in place during daylight working hours. As the works progress into other phases the temporary traffic management will move along the A82 with advance notice given at each new phase.
