Investigative work on Aberdeen’s Broad Street will be carried out next Monday ahead of an ambitious pedestrianisation programme.
Construction will take place close to Marischal College’s main entrance, but employees and visitors will have access via the disabled entrance.
The site investigation is due to be completed by next February 17.
The planned changes to Broad Street, which were backed by councillors last summer, include a mini-roundabout and a toucan crossing at the Union Street/Broad Street junction.
Other key features include a raised grass planter to provide views of Marischal College and granite bench seating in some areas.
The work, between Upperkirkgate and Queen Street, is expected to start in the coming weeks and last around six months.
It is being turned into a pedestrian-priority street as part of the city centre masterplan, which aims to transforms the city centre during the next 25 years.
The initiative includes four major transport projects on Broad Street, Guild Street, Union Street and Schoolhill.
Deputy council leader Marie Boulton said: “The investigative work should be finished quickly and there shouldn’t be too much disruption as it’s on the paved area outside Marischal College.
“We look forward to the changes happening in the area as part of the City Centre Masterplan project.”
