The challenge was to convert an existing 2-lane highway into a four-lane expressway in the terrain that is hilly and dense. The region also receives the highest rainfall and part of the highway is among the wettest regions in the country. This called for slope stabilisation and soil erosion solutions.
the tsolution involved Expressway plan and construction, Toll facilities solutions, heavy vehicle bays, service lanes, rest areas, fuel service facilities, lighting systems, communication systems, traffic management solutions, landscaping, arboriculture and all other related project facilities. The expressway runs a total length of 68 kms from Jorabat in Shillong, Assam into the state of Meghalaya.
VALUE ADDITIONS
Considering the region is an ecologically sensitive area with very heavy rainfall during the monsoon and the varying terrain conditions from hills, valleys and dense forests, Antea Group also provided solutions for water conservation and slope stabilisation. The expressway corridor was hedged with vetiver grass to conserve the soil even in the monsoon season. This grass is not native to the region and was implanted for slope stabilisation.
