It is one of the busiest routes out of Sheffield – but the A57 Manchester Road has been closed for three weeks aftera landslide.
Emergency repair works by contractors Amey have been carried out virtually around the clock to get the vital route open again.
And on Monday it will finally be operational again – though only for single lane traffic.
A section of the carriageway at Crosspool has been closed from Hagg Lane and Coldwell Lane to the junction of Rivelin Valley Road throughout most of November.
Construction manager Andrew Harley, who has been directing the work as part of the Streets Ahead project, said: “Our team have done a great job, often working in terrible weather, and have carried out a huge amount of work during the three-week closure.
“We’ve dug deep under the road to replace a damaged drain and dug out more than 700 tonnes of clay and rock and install supports to help prevent further land movement.
“We are now ready to make further repairs on the upper embankment and plan to have the rest of the work finished and the road fully reopened by the end of January.”
Coun Jack Scott, Sheffield Council cabinet member for environment, recycling and Street Scene, welcomed the reopening.
Hesaid: “It’s great this stage has gone so well and the A57 is ready to reopen.
“I’m very aware of the disruption caused to motorists by this landslide so we are pleased to move onto the next phase of work to prevent similar problems in the future.”
The next phase of work will last until the end of January when the road will be fully reopened to two-way traffic.
Work to complete a major Sheffield road project is set to be completed by mid-January – but traders say the six-month scheme is costing them money.
They say traffic restrictions at Meadowhead roundabout are keeping shoppers away.
A £1 million scheme to reshape the roundabout began in July, with much of the work outside peak hours on Sundays.
John Mitchell, owner of Mitchell’s Wines, close to the roundabout, said: “It has affected us no end. People keep hearing about the traffic restrictions and think ‘I’m not going anywhere around there’.”
Neil Grant, managing director of Ferndale Garden Centre, Coal Aston, said: “For us to find a major route close to the business shut on every Sunday before Christmas beggars belief.
“Why not carry out the work in January or even October when businesses and consumers aren’t under so much pressure?”
Coun Leigh Bramall, Sheffield Council cabinet member for development, said: “The long-awaited improvements are as direct result of people and business in the area telling us the current roundabout system did not work.
“We are sorry this work may be causing initial problems, but I am confident the long-term benefits will make it worthwhile. This work will reduce journey times, improve safety and ease congestion.”
