Improvement works will be done in phases and last several years
A historic Stirling bridge will reopen fully to traffic about 10 days ahead of schedule after the first stage of major repair work.
The B-listed Stevenson Bridge, which carries more than 16,500 vehicles a day on the A9, was built to span the Forth by Robert Stevenson in 1831.
The crossing was closed to southbound traffic while work to repair pipelines buried within the structure took place.
Stirling Council has announced the bridge will reopen on Thursday.
The Causewayhead bridge, as it is also known, serves as a direct route into Stirling from sites such as the Wallace Monument and Stirling University and concerns had been raised about the impact the lane closure would have on tourism.
The bridge has already passed its expected lifespan of 100 years and has carried more traffic than it was designed for.
Work to expand the life of the crossing even further is taking place in phases and is expected to take several years to complete.
Future work will include refurbishing the bridge parapets, improving the lighting and footways, waterproofing and resurfacing.
