The 2013 plans for the project axed the traffic lights at Cedar Street, Cardiff, but added a new set to compensate at Norfolk Street, 200 metres west.

The new design shows traffic lights at neither intersection.

Cedar Street and surrounding residents can turn left or right onto Main Road. However, this will change to a left turn only.

Those who wish to drive to Cardiff must first drive to Glendale and use a roundabout to change direction.

The change has been penned because, under the project's first stage, Glendale Drive, with which Cedar Street aligns, must be realigned to the west so Pennant Street can be connected to Main Road, Glendale.

The council's initial plan to replace the Cedar Street lights with a staggered T-intersection at Norfolk and Lowry streets was rejected by Roads and Maritime Services.

During community consultation, 101 public submissions were made.

One of those residents was Adam Gibson, who lives on Boston Close.

He said the new design was "completely negligent and done in a rush".

Mr Gibson and his neighbours received notice of the changes via a council letterbox drop.

"This new little change was snuck through in a newsletter," he said.

"The fact that [the council] didn't even consider turning right from the new Glendale Drive into our area undisputedly demonstrates how little thought they put into their alternative."

The matter went before the council on Monday as The Star went to print.

Staff recommended councillors approve stage one, section one of the project, including the changes to Cedar Street.
