SOUTH DELHI—The deadly heat wave gripping India in recent weeks has claimed more than 2,000 lives and has not spared the nation's structures in the process.

Among the lesser casualties: road markings, which have been melting away from asphalt streets gone gummy.


Asphalt roads in India's heat-seared southeast have gone soft, liquefying the paint in the process.

News stories and photos of the liquified markings have gone viral, inciting public anger.

'Not Supposed to Melt Away'

"Yes, the temperatures are very high, but the marking on roads [is] not supposed to melt away and disappear altogether," Himanish Raghunath reports on

"This shows the poor quality of materials used by the respective authorities in constructing the roads of our country or Delhi in this case."
Heat waves are not uncommon from March to June in the region, but experts say climate change has brought longer, drier, more intense spells this year.

Pedestrians avoid the crosswalk goo that once was road paint. "Yes, the temperatures are very high, but the marking on roads [is] not supposed to melt away and disappear altogether," fumed one reporter.

The recent blast is caused by lack of rain and "dry, hot winds from the desert state of Rajasthan," reports Attila Nagy on Gizmodo.
113 Degrees
Temperatures have topped 100 degrees in many cities for the past two weeks, killing more than 2,000 people as of Sunday (May 31) and exposing the nation's other vulnerabilities, including "the poor quality of materials used in construction our roads," reports Raghunath.
Temperatures could remain around 113 degrees Fahrenheit in the capital of New Delhi, home to 23 million people, reports Gizmodo.
The devastation is worst in the southeastern states of Andrhra Pradesh and Telengana, according to the Associated Press.
Relief is expected with the start of monsoon season, which begins this month.
