Date set for construction of 3m-high noise barrier on the M27 - with closures and diversion announced
HIGHWAYS bosses have announced when construction will begin on a 3m-high blue barrier on the M27 – geared at reducing noise pollution into Port Solent and Farmlea Road.
The structure will run from the Cosham link road at J12 of the M27 to the bridge which carries the M27 over the railway line near Paulsgrove.
Its construction follows a years-long successful campaign led by Port Solent residents and the MP for Portsmouth North, Penny Mordaunt.
Highways England announced in November the project would begin in mid-January, but has now singled out a specific date.
It will coincide with work to replace the bridge joint on the Cosham link at J12 of the M27, which will see the central reservation removed.
Work is set to begin on Monday, January 27 and is expecting to conclude in early June. It will take place overnight between 9pm and 6am.
However, a host of traffic restrictions have been announced to ensure the safety of Highways England workers.
At 'varied stages’ of the work, these will see:
:: Overnight closures on the M27 westbound carriageway
:: Overnight closures of the Cosham link at J12, from the A27's Southampton Road junction to the M27
:: Daytime lane closures with a 40mph speed limit on the Cosham link at J12
:: Overnight closures on M27, between J11 and Portsbridge Roundabout
:: Occasional full weekend closures of the Cosham link at J12
Highways England has also announced a diversion, pictured, that will come into play when the Cosham link bridge and the westbound entry slip at J12 is closed.
Traffic will be sent onto the M27 eastbound carriageway, south down the M275 to the Tipner Roundabout, around the junction then back up the M275, taking the link to the M27 westbound carriageway.
Drivers on the A3 Southampton Road and A27 Southampton Road, eastbound, who want to get onto the M27 at J12 will have to use the A27 Western Road to access the Cosham link.
Highways England said the closures had been ‘carefully programmed', but could change because of weather or ‘unforeseen circumstances’.
