Perth Bridge is scheduled to be partially closed again, fewer than two months after the council abandoned bollard installation work on the historic structure.
The planned eight-week closure comes as Perth and Kinross Council officers approved a second application to place bollards on the bridge.
Restrictions will be placed on the crossing from July 8 – seven weeks after the local authority partially shut the road for a fortnight, despite not carrying out any work.
Council officers came under fire in May for partially closing the busy road then abandoning the plans, saying further investigation work was required.
Officials have now recommended approval of new plans to install the bollards, despite the application being submitted on April 30, three weeks before the original work was abandoned.
The bridge was restricted from May 7 for around two weeks before the work was called off when council officers found the depths of the pavement were “not as drawings of the bridge had led us to believe”.
The council said the plans were revised again on May 29, after the application was submitted and they are “confident” work will go ahead.
The northbound lane of the bridge is scheduled to be shut again from July 8 until August 30 from 7pm to 7am, though the local authority has yet to confirm the closure is related to the installation of bollards.
Temporary signs warning drivers of an upcoming road closure were placed on the bridge earlier this week.
A Perth and Kinross Council spokesperson said: “We can confirm that the listed building consent approval was based on revised plans that were submitted on May 29.
“We are confident that the bollard installation works detailed within this approved application will go ahead in the near future.”
Council chiefs want to install the bollards as a safety measure to protect the 18th century structure.
The historic bridge does not have sufficient support beneath its footpaths to carry the weight of modern vehicles and it is hoped the bollards will stop drivers from mounting the kerbs.
