Ballochmyle councillor, Linda Holland, has said she'll do everything in her power to ensure last week's road "chaos" doesn't happen again.
Work was due to be carried out on the A70 road at its junction with the B743 on Saturday, July 15.
East Ayrshire Council (EAC) said a "near miss" occurred on the site, meaning that alternative measures were taken into effect.

Work was instead carried out from Monday to Wednesday, with road closures in place from around 7am until around 6pm each day.
The closures meant anyone driving between Lugar and Muirkirk faced a near 40-mile diversion.
EAC apologised for the inconvenience caused by the issue.

Now, Ward 7 Labour representative, Linda Holland is vowing to resident that she'll do what she can to ensure something like this never happens again.
Cllr Holland said: "We must make sure something to this extent doesn't happen again.
"Muirkirk can be an isolated area at the best of times, without shutting off one of the main roads to it for three days.
"I think the main issue with the whole thing was the lack of communication that it was happening.
"People thought the work was being carried out on Saturday, and then all of a sudden the get up for their work on the Monday and the road is closed.
"I was getting angry emails and messages from people and I can understand that."

Cllr Holland added: "I can't pass on information if I haven't been given the information in the first place.
"I want to see if there's a way that information like this can be passed to local representatives when it's posted online, because a lot of people check out our Facebook pages for information, and that goes for other wards as well.
"I hope this doesn't happen again, because we can't afford for it to happen again.
"I'll do everything I can to make sure lessons are learned from this."
A spokesperson for Ayrshire Roads Alliance, on behalf of East Ayrshire Council, said: "The Ayrshire Roads Alliance is committed to ensuring that road users and local residents are notified of any planned roadworks or emergency roadworks as quickly and effectively as possible.
"There are always learning points from situations that arise due to unforeseen circumstances and the Alliance will continue to liaise with Cllr Holland, and all local elected members, to continue to improve the notification process."
