HI-TECH FIX FOR SHANKLIN STRUCTURE


A hi-tech solution to seal and strengthen the culvert underneath Victoria Avenue/Shanklin Road, through which Scotchells Brook passes, is to begin next week.

Island Roads will use an inflatable resin ‘balloon’ liner which is pulled through the structure, sealed at both ends and then inflated to fit the aperture. UV lighting is then used to cure the resin, providing a protective, hard-wearing liner which will strengthen and protect the original brickwork.

Because the brook is several metres below road level, a special temporary ramp will need to be constructed to get the necessary equipment and materials on and off site.

The inflated resin liner technique has previously been used by Island Roads to perform a similar function at several smaller bridge structures, including Holbrooke’s Bridge in Bouldnor – home to the award-winning ‘eelevator’ which assists migrating eels.

Ian Hodson, Island Roads structures manager, said:

“This is a difficult work site given that it is a confined space and also several metres below the road level.

“But it is vital we stabilise and strengthen the culvert given the major disruption that would occur if it were allowed to deteriorate, or even collapse.

“The work we will be undertaking here is the last of four schemes across the Island this year, using an innovative and rapid solution which will allow us to extend the life of the structures with the minimum disruption.”

The work has to be carried out in the summer months when the water course levels are expected to be low, but has been programmed for completion before the main school summer holidays.

Work will begin on Monday (15th July) when the temporary ramp structure will be created. This will be done overnight between 18:00 and 06:30 during which time there will be a road closure in place at the western end of Victoria Avenue, with traffic diverted via Lake, Apse Heath and Canteen Road.

The road will also be closed during the day from 09:30 to 21:30 on Wednesday 17th July while the liner is installed. Again the diversion will be via Lake and Canteen Road.

Then on Thursday 18th July the road will again be closed overnight (18:00 to 06:30) to allow the equipment to be removed from site. It will also be necessary to control traffic via temporary traffic lights throughout the work programme.

Ian said:

“We apologise for any inconvenience but we are working overnight where possible on a scheme that is necessary to improve what is an important – if largely unseen – part of the Island’s infrastructure.”

These brick lined culverts are works of art. It would be interesting to know how they were built, Did they tunnel and use wooden form-work or was it a cut and cover operation. I believe that road only dates from the late 19c

Island roads mafia more disruption
Winter jobs that could be done after summer but no just put more lights up in the baking sun.
Or is winter just to fill pot holes in the freezing weather so they can keep re doing them.
I just dont get island roads mafia.
