However, it has not been announced whether the work will force more lane or carriageway closures, disrupting traffic.

Tasks include concrete, painting and various snagging work, according to Transport Scotland.

“Architectural lighting” to illuminate the £1.35 billion structure has also to be finished, the Scottish Government agency said.

The bridge opened on 30 August, but one carriageway has already been closed for five days for repairs after surfacing around expansion joints was laid too high.

Southbound traffic was switched to the Forth Road Bridge during the work in November/December.

Snagging includes galvanising repairs to the "vehicle restraint system", work on windshielding post bolts and louvres and "bearing remedials" on two of the bridge piers.

There is also snagging to road lighting and road drainage.

Other tasks include completion of equipment inside the bridge deck, such as a dehumidification system to protect against corrosion, a network of monitors that provide alerts of any structural problems, and the tower lifts.

Four painting tasks, involving the outside and inside of the structure, won't even start until the spring.

Concrete "finishing" is needed on the towers, piers and deck edge cantilevers.

The list was published by the Scottish Parliament’s rural affairs and connectivity committee after members requested the information when they questioned bridge officials in November.In a letter to the committee, Transport Scotland said the work had to be complete within a year of the bridge opening.

Major transport infrastructure projects director Michelle Rennie said: “Finishing works and snagging are to be completed within the first year of the five-year defects correction period.

“This means that the contractor has until 30 September 2018 to complete the remaining outstanding works and snagging

“The programme for undertaking these works is determined by the contractor.

“However, this is subject to change for a variety of reasons including weather sensitivities, availability of resource and progress on other activities.”
