Nov 12, Colombo: Sri Lanka Deputy Minister of Transport Nirmala Kothalawala says that two teams have been assigned by the Southern Expressway authorities to observe the earth mounds lining the road on a daily basis.

They are to monitor the condition of the land by the sides of the Expressway especially during the periods of rainy weather.

Environmentalists have criticized the construction of the Expressway when a 25- feet high earth mound collapsed over the Expressway on November 02, blocking around 200 meter section of the southbound lanes.

However, the vigilance of the expressway staff helped to take preliminary safety measures closing a part of the road for traffic and no damage to life and vehicles occurred.
