Transport Scotland is set to award a £200,000 contract to URS Infrastructure and Environment.
The company is due to carry out a feasibility study on the A720 Sherifhall roundabout, which forms part of Edinburgh city bypass.
Transport minister Keith Brown said: “This Scottish Government is fully committed to speeding up journeys on our key roads connecting people with education, leisure and employment opportunities while ensuring businesses have reliable routes to markets.
“Sheriffhall roundabout is the only junction on this key road that does not have a flyover junction, leading to lengthy tailbacks, especially at rush hour. The purpose of this initial work is to look at possible junction improvement options and to get a better understanding of the difficult ground conditions in the area.”
Sheriffhall roundabout is a challenging location as a geological fault runs through the roundabout and there are extensive mine workings in the area.
Work will also look at future transport growth in this area, as well as how this fits with other junctions at this part of the A720.
