Contractors are working between the two townships.
The Clutha leg begins at the Beaumont end of Millennium Track and finishes at Cockleshell Rd, in the Evans Flat area near Lawrence.
SouthRoads won the contract for that section of the trail.
Trail project manager Tim Dennis, of Southern Land CKL, said SouthRoads staff were making great progress on the 15km section from Beaumont to Evans Flat.
"The weather had hampered progress, but SouthRoads are getting stuck in now and doing a great job. All we need is a good run of weather."
Waitahuna-based Homer Contracting has nearly completed work on the section from Evans Flat to Lawrence.
Mr Dennis and the trust hoped the whole trail would be completed by the end of the year.
The 73km trail, which will cost an estimated $5.5 million, was the first in Central Otago to receive funding under the New Zealand Cycle Trail project.
The Government contributed $3.8 million.
A 20km section is planned in the Clutha district, between Beaumont and Lawrence, and the remaining 53km will be in Central Otago, from Lake Roxburgh to Beaumont.
The trail is being constructed in six sections.
The Clutha District Council is running workshops designed to help facilitate ideas and identify opportunities for the community arising from the Clutha Gold Trail.
The first workshop was held in November last year and a full-day workshop is to be held in Lawrence on Sunday.
