Two months after its closure when a part of the road caved in, Infrastructure Malta started crucial works for the strengthening of the upper part of Saqqajja Hill in Rabat. Contractors started digging deep holes around six storeys, in which foundation systems will be placed with 34 concrete and steel pillars to separate this road built of layers of weak rocks and clay, which led to its collapse two months ago.
The project’s architect, Anton Zammit, said that workers will place in the holes steel nets which will be filled with solid concrete to resist water degradation. “The friction piles columns are being placed in a depth of six story on clay ground, and if movement occurs in upper storeys, the road will not be affected”.
The work on the €1 million project started suddenly in the end of May after a section of the road caved in on the underneath valley during a storm.
Geo-technical studies started immediately by the agency’s architects and other experts to identify the road situation and the rock, clay and other material layers underneath the road.
The agency is collaborating with the Cultural Heritage superintendency to ensure that every intervention in the road protects the historical heritage in these areas of importance where archaeological remains may be buried in the area.
Architect Zammit stated that the road is expected to be opened for traffic by the end of September.
