The 1.8 kilometres of tunnelling work was done by China Civil Engineering Construction Corporation.
Softer blasts were used to make the tunnel because of the terrain.
The tunnel is part of a 145-kilometre link from Dubai and Sharjah, through the Hajar Mountains, towards the emirate of Fujairah.
The route passes through some of the most complex topographical areas in the network.
The project includes building 15 tunnels through the Hajar Mountains with a total length of 16km as well as the construction of 35 bridges and 32 underpasses.
All tunnel excavation operations were carried out in line with international best safety practices, state news agency Wam reported.
