Specialist workers are set to carry out repairs on the A53 flyover at Etruria next week.
The road has been closed since Tuesday (9 July) due to safety concerns.
A city council spokesman said: “As a result of works on site yesterday, we have now received detailed information from bridge maintenance specialists with regards to work needed to be completed on the A53 flyover.
"Road users may have noticed that we haven’t been on site during the day today, but much work is progressing and we can now explain what works will take place.
“The bridge is supported by two steel expansion joints that sit above the two columns that link the overhead carriageway. On one side of one of the joints, on the northbound lane heading towards Cobridge, a minor fracture has occurred between the resin that holds the joint in place and the Tarmac road surface. The cause of this defect is not confirmed, but it could be related to improvements needed to a waterproofing course.
“We are very mindful that this road is on a busy commuter route, and of the need to ensure that traffic flows. This is balanced against our priority to ensure the safety of all road users.
“As such, we can confirm a series of interim works will take place that will ensure the road can reopen fully and safely. This will involve resurfacing a large section of the carriageway, replacing a section of the joint with a new steel section which will be supported and filled to ensure the road surface and joint is fully repaired and watertight.
"The specialist contractors needed to complete this work are responsible for carrying out bridge maintenance, repairs and emergency works on the M5 and M6. Given this, we have made arrangements so that they can be on site on the A53 as early as possible, from Tuesday. It is anticipated that this work could take at least two days to complete, and we hope that the road will be fully open as soon as possible before the end of next week.
“We will return to the flyover later in the summer to carry out a full programme of works. This will be during the school holidays, when there is less demand on the road, and will be planned to give motorists as much notice as possible, with the potential to do the work in the evening and overnight to keep any disruption to a minimum.”
