The highway was originally constructed by Japan International Cooperation Agency (JICA) between 2008 and 2011.
The photographs showing huge cracks on the road section that went viral on internet gave a glimpse to the outside world of the scale of damage caused by the quake in Nepal.
The technical teams from both government and non-government agencies who inspected the site attributed the damage to the soft soil topography that was unable to sustain the infrastructure built over it during the disaster.
The JICA's restoration work included closure of crack gaps, reconstruction of pavement structure, water proofing over pavement surface cracks and blacktopping.

Road after maintainence by JICA.
"This road has been designed not only for the smooth transportation of goods and people between Kathmandu and Bhaktapur, but also to play an important link between the Kathmandu Valley and the eastern Tarai via the Araniko Highway," read the JICA statement.
With the maintenance of the road completed, the traffic congestion seen during the maintenance period has eased. Likewise, the traffic signal at Kausaltar, which had stopped after the quake, has also been maintained. No accidents were reported during the construction period, read the JICA statement.
The JICA supported the restoration on the request of Department of Road as part of its "Project on Urban Transport Improvement for Kathmandu Valley."
