The current proposal would lead to the creation of a 13km-long tunnel with a seven-metre radius and one traffic lane heading in either direction, with an additional safety lane.
Serious concerns have been raised about the environmental impact of the project and about how it might accelerate the construction activity that is already changing the face of the island.
Natural land would be eaten up for the tunnel’s two entrances
Environmental groups have flagged how arable and natural land will be eaten up for the tunnel’s two entrances and the authorities have to somehow cater for the unprecedented volume of one million cubic metres of waste generated from the tunnelling.
Respondents who said they voted for Labour in 2017 were more likely to give the greenlight to the tunnel, with 54 per cent saying they agree with it and 29.5 per cent disagreeing.
A total of 10.6 per cent said that they are neutral about the matter and six per cent do not know.

Party leader Bernard Grech has pledged to hold a referendum for Gozitans on the tunnels project.
