An online petition has been set-up to save the iconic Grandstand scoreboard.
It states the Department of Infrastructure is planning to start the second phase of roadworks on Glencrutchery Road in late 2015 - engineers have examined the scoreboard and concluded it is unfit to be re-erected.
The introduction to the petition compares losing the historic scoreboard to removing Ballaugh Bridge from the TT Course.
Over 500 have signed the petition since it was set up on Wednesday morning.
There is also a Facebook group page with nearly 700 likes.
A statement Manx Radio has received from the department says it is planning to refurbish Glencrutchery Road.
It goes on to say it is currently estimated that scheduled work will take place in 2017 or 2018, depending on the progress of any work on Douglas promenade.
The Glencrutchery Road scheme will include the requirement to dismantle the scoreboard while it is carried out.
DoI structural engineers have assessed it is likely the steel which supports the scoreboard will need to be replaced.

The Department of Economic Development understands the passions of the fans and of the importance of the history and heritage associated with the scoreboard.
No decisions have yet been made but these will be factors taken into account in any final decision.
The Department of Economic Development's Motorsport Team is currently reviewing all options including a manual scoreboard, a digital scoreboard or a combination of the two.
