Superpave will reduce traffic noise from flyover to Hogarth Roundabout
Transport for London have begun to resurface the A4, between the Hogarth Roundabout and Hammersmith Flyover, with a new generation of quieter asphalt known as Superpave.
Working overnight to avoid causing traffic disruption during the day, TfL engineers are using a ‘stone matrix’ asphalt with smaller aggregate than traditional hot rolled asphalt.
The 14mm thick superpave provides a far more flexible surface which reduces traffic noise, according to TfL.
TfL workers are also treating the concrete joints beneath the road as part of the work which will improve stability of the running surface and further reduce noise.
The resurfacing started on Monday August 12 and is due to last until the end of August. 90,000 motorists use this section of the A4 every day and lane closures and restrictions are in place between 10pm and 5am.
While these works are taking place, Hammersmith and Fulham Council say there is growing support for proposals to build a tunnel to replace this stretch of road.
Since its emergency closure in December 2011, questions have been asked about the long-term viability of the 50 year old flyover given the escalating costs of maintenance and increased risk of failure.
This has led
West London Link Design, a group of nine respected local architects to propose the tunnel - already nicknamed the "flyunder" -
leading from the Hogarth roundabout in Chiswick to the Earl’s Court end of the flyover.
Councillor Victoria Brocklebank-Fowler, H&F Council cabinet member for transport and technical services, says: " The A4 scythes our borough in two creating noise and pollution for local residents.
" The reduced noise from this special tarmac will be very welcome for residents living near the road. In the longer term the ultimate solution to virtually eradicate traffic noise and pollution is to replace large sections of the A4 – including the flyover – with a flyunder."
