The chief engineer of the Forth Replacement Crossing project is leaving the post for a new job in the Middle East.
Project director Carlo Germani is to leave this month for Qatar, after three-and-a-half years in the post.
Officials said they expected to appoint a new project director “in the coming weeks”.
A Transport Scotland spokesman said: “After three and a half years on the Forth Replacement Crossing (FRC) project, Carlo Germani has informed us that he is to leave his position as project director for Forth Crossing Bridge Constructors.
“Carlo has made a hugely significant contribution to the successful delivery of the FRC project to date.
“We’d like to pay tribute to that contribution as he prepares to move on to new challenges in Qatar. He leaves the project in a very healthy state as we move towards its final two years.
“Arrangements are in place to ensure a smooth transition and our contractors Forth Crossing Bridge Constructors (FCBC) expect to appoint a new project director soon.
“The crossing project remains on time and under budget.”
