REPAIRS will be carried out to a major Hull road, which appears to have melted during the recent heat wave.
It seems that, as the city sizzled in temperatures that almost topped 30C (86F), Daltry Street flyover melted.
Now, drivers leaving the A63 have bumps, as well as potholes, to contend with as they enter the city centre.
The Highways Agency, which is responsible for the upkeep of the flyover, along with the A63, plans to include repairs in work already scheduled to take place in the next few days.
A spokesman said: "We are aware of a surface defect on the A63 Daltry flyover in Hull, which is affecting a small section of lane one.
"As the defect does not pose an immediate safety risk, it does not warrant immediate action, but will be repaired during a planned overnight closure of the A63 eastbound carriageway on Tuesday.
"During the closure, we will also be replacing white lines and road studs.
"We are investigating the cause of the defect and will continue to monitor the road conditions in this area to make sure the fault doesn't worsen."
Graham Hall, assistant head of service for Hull City's Council transport and management department, said the local authority has not been made aware of any similar problems on its road network.
He said: "Heat can damage a road surface, but no one has reported any damage to roads or footpaths elsewhere."
According to the Met Office, the highest temperature of the year so far in Hull was 28.9C (84F), which was recorded on July 18 at East Park.
Dr Howard Robinson, chief executive of the Road Surface Treatments Association, said: "Asphalt is like chocolate – it melts and softens when it's hot, and goes hard and brittle when it's cold. It doesn't maintain the same strength all year round."
He has been reported as saying most roads in the UK that experience a reasonable amount of traffic will start softening at 50C.
However, temperatures are typically measured by the Met Office in shade and Dr Robinson believes some roads, especially those that are exposed, could record such a temperature.
Elsewhere, some councils have taken the unusual step of deploying gritters to spread rock salt, which helps lower the surface temperature, protecting the tarmac from the heat.
During the summer of 1976, the Mail photographed firefighters spraying water on to Clough Road swing bridge after the structure expanded in the heat, preventing it from opening.
Despite a disappointing past few days, with grey skies and even thunder and lightning in places, East Yorkshire can expect the sun to return today.
Met Office spokesman Tony Gray said: "To begin with, it will be rather dull, with mist and hill fog in places, but this will disappear quickly.
"We are expecting long, sunny spells. It will feel very warm, really quite humid away from the coast, with a maximum temperature of 27C (81C) in Hull."
Tomorrow will also start off sunny and will remain so for most of the day, although the weekend forecast looks rather unsettled, with cooler temperatures and rain possible.
By Sunday afternoon, the temperature could drop to as low as 21C (70F).
