The northbound Sta Venera tunnel, which takes traffic from Marsa towards Tal-Qroqq, was closed for over two hours this evening because of an increase in water seepage.
The tunnel was closed at about 8 30 p.m. as a quantity of water flowed into the tunnel from the roof.
A government architect and workers from the Water Services Corporation were on the scene.
The southbound tunnel remained open.
