The Federal Controller of Works,Olukayode Popoola,on Tuesday, announced a 72-hour total closure of the Third Mainland Bridge to cast concrete on the expansion joints.
Mr Popoola told the News Agency of Nigeria (NAN) in Lagos that the shutdown will take effect from midnight on Saturday to midnight on Tuesday.
He added that construction works had reached the stage for casting concrete on additional three expansion joints.
“There is going to be total closure of Third Mainland Bridge in order to allow for the casting of three number expansion joints on the Island Bound lane
“By the time the Christmas is winding down which is 12:00 midnight, we are going to close it so that we will be able to cast the concrete on Saturday the 26th and 27th we cast again.
” And we need about 72 hours for this concrete to set. Therefore, the opening will be on the 28th December midnight, that is 72-hour closure.
“This is to prevent vibration of the bridge. If we allow vehicles to be moving on one lane, there is going to be vibrations and the concrete will not set properly,”he said.
The controller said all the alternative routes were in good condition and traffic regulatory agencies had been deployed to effectively divert and manage traffic to avert gridlock.
He appealed to road users to cooperate with traffic regulatory agencies.
Mr Popoola also announced a 48-hour partial closure of the Lagos-Ibadan Expressway from Dec 28 to Dec 29 to complete some work on a fly over bridge on the project.
“The contractor, Messers Julius Berger wants to install cross beams at Kilometre 16, that is, around MFM,” he said.
He explained that the piers were already standing on both sides of the road and the contractor was to lay the cross beam on top across the road.
“That area will be cordoned off, there will be closure within that section from 12:00pm on 28th of December and it will be opened to traffic by 5:00am the following day.
” 200 meters to get to that particular location we have diversion and another diversion 200 meters away from that place.
“One lane will be opened to traffic, it is only one lane we are closing to traffic at a time. The first lane that we are going to close is outward Lagos, that is the Ibadan bound carriageway, we will close it on the 28th.
” And then the second day which is 29th, we are moving to the other lane which in inward Lagos. The same 12:00pm to 5:00am,” Popoola said.
He appealed for patience and understanding of road users saying that the construction was part of the progress that the Federal Government had achieved on the project.
“We regret all the inconvenience and hardship this might have created,” he said.
He said all the construction zones had been cleared and the highway had been opened to traffic which was responsible for seamless movement on the road.
The Third Mainland Bridge in Lagos, which was going through a series of repairs, had to be partially shut on July 24 for another round of rehabilitation works.
The repair, expected to last six months, was extended by one month due to the recent #EndSARS protests in Lagos extending the completion date from January 2021 to February.
The construction was initially divided into two phases of three months on each carriageway, starting with the Oworonsoki bound carriageway whose completion dragged to four months.
Traffic was partially diverted on a stretch of 3.5km where construction is ongoing between Adeniji Adeniji Ramp and Ebute Meta, while different time belts were allotted for traffic diversions on the bridge.
The 11.8km bridge is the longest of the three bridges connecting Lagos Island to the Mainland.
The bridge starts from Oworonshoki, which is linked to the Apapa-Oshodi Expressway and the Lagos-Ibadan Expressway and ends at the Adeniji Adele Interchange on Lagos Island.
Constructed in 1990, the bridge was adjudged as the longest in Africa until 1996 when the Oct6 Bridge in Cairo, Egypt, was completed.
The reconstruction/rehabilitation of the Lagos-Ibadan Expressway on the other hand was flagged off in 2013 by former President Goodluck Jonathan and was awarded to two firms.
Julius Berger is constructing section one which spans from Ojota in Lagos to Sagamu Interchange while RCC is working from the Sagamu Interchange to Ibadan.
