Julius Berger Nigeria Plc., the contractor handling Section One of the reconstruction of the Lagos/Ibadan expressway project, has commenced the installation of expansion joints on the highway’s popular ‘long bridge.’
Section two of the project, which spans from the Sagamu Interchange to Ibadan, is being handled by the Reynolds Construction Company (RCC).
According to NAN, the highway has been completed to the final layers on both carriageways between the Redeemed Christian Church of God (RCCG) Redemption Camp and the Sagamu Interchange.
However, some drainage works were ongoing on the Ibadan-bound carriageway.
The Federal Ministry of Power, Works and Housing engineer supervising the contract, Kayode Ibrahim, explained that special construction materials were being used in the reserved spaces called “Thorma Joints,” which are where the expansion joints are being installed.
Since bridges are not static, he explained that the expansion joint was to hold the bridge firmly as it expands and contracts.
He further explained that the installation of the expansion joints began on Thursday, which would replace 42 joints on each side starting with the Lagos bound carriageway.
“Our usual effective traffic diversion and control measures are on, to ensure minimal stress to motorists,” Ibrahim said.
He however, declined comments on when the installation of the joints would be completed, insisting that the company would complete the work “very soon.”
Meanwhile, the engineer explained that Julius Berger was working on the road’s shoulders (edges) between Wawa and Ibafo, in order to move traffic to the Ibadan-bound carriageway.
He said this was to enable effective reconstruction of the Lagos-bound carriageway.
Ibrahim stated that Macadam which is a water resistant component, was being used to construct the highway, to make the construction last up to 50 years.
He added that the drainage network was being channeled to an existing river, to avert flooding.
