Brisbane Racing Club track manager Sean Bridges has resigned and will finish up almost immediately.

Bridges has been the track manager at Eagle Farm for about five years.

He met with BRC officials earlier this week about a possible restructure of the track management during next year's remedial work on the troubled Eagle Farm course.

Bridges, who was due to go on holidays on Thursday, sent his resignation to the BRC on Tuesday afternoon which caught officials by surprise.

BRC Chairman Neville Bell confirmed Bridges had resigned but emphasised he had not been dismissed,

"We accepted Sean's resignation with major regret. He has been a very hard worker for us," Bell said.

He said he could not comment further on likely replacements until discussions with Racing Queensland which is overseeing the Eagle Farm reconstruction.
