The Transport Ministry has allocated €10 million for a revamp of Malta's four main road tunnels, Roads Minister Ian Borg said on Monday.
He said the revamp will involve the tunnels at Kirkop, Sta Venera, Tal-Qroqq and Ta’ Giorni.
While the tunnels are structurally sound, the works will focus on maintenance and making them safer for motorists, the minister said.
The works will include cleaning, repairs and installation of modern lighting, CCTV, fire alarms, fire hydrants and air quality monitoring sensors.
Emergency escapes will be improved and equipped with call stations, new signage and protective doors.
A control room will be set up to monitor all four tunnels.
The tunnels will be lined with new material for ease of cleaning and better visibility.
Works will start later this year once all contracts are awarded.
