Hampshire's roads could start melting as sizzling temperatures continue to soar
Roads could be impacted as the heatwave continues
Drivers are being warned that roads could become soft or even start to melt as the heatwave continues.
Hampshire County Council highways teams are keeping a close eye on roads during the spell of extreme hot weather, with surface temperatures expected to climb to 60°C in some places.
The council is responsible for maintaining more than 8,500 kilometres (5,300 miles) of highways across Hampshire, and crews are monitoring the network for signs of heat-related damage.
While air temperatures may be much lower, dark road surfaces absorb heat and can become hot enough for tarmac to soften and break up.
This can leave roads uneven and create difficult driving conditions for motorists. To help prevent damage, gritters are on standby to spread crushed stone on roads most affected by the heat. The stone helps protect the softened surface and improves grip for vehicles where surfaces have begun to soften.
The warning comes as a lane of the A3 has been closed after it became uneven in the hot weather. The closure is on the northbound side between the end of the A3M stretch at Horndean and the B2070 to Petersfield.
The National Highways says that “the defect is related to extreme weather conditions”.
Meanwhile, drivers are being urged to take extra care and check road conditions before travelling. They should also make sure their vehicle is in good condition, carry plenty of drinking water and allow extra time for journeys.
People are being advised to travel early in the morning or later in the evening where possible to avoid the hottest part of the day.
