A narrow country road in west London has been replaced with a wider road, as part of the HS2 railway project.
The HS2 railway would have needed to pass underneath the existing road that runs through the area, but as part of the agreement to build the railway, a new road wider road was built next to the old one.
A new cut-and-cover Copthall Green tunnel was dug next to the old road, and a slab on top was preinstalled to carry the new road over it. The newly built 900-metre length of straight road replaced the slightly curving older Harvil Road and opened to road traffic last week.
Each carriageway – with a width of more than three and a half metres – is wider than the road it replaces, and includes 1.8 metre wide footpaths replacing a narrow single footpath that the old road had.
Skanska Costain STRABAG, the HS2 main works civil engineering contractor for the route area, carried out the works.
Skanska Costain STRABAG JV Managing Director James Richardson said: “As we complete sections of the new railway, improved local infrastructure such as Harvil Road can be used early, improving journeys through the area and supporting local communities. The section of road we have opened runs over the new Copthall tunnel, through which the new high speed trains will run.”
The pre-existing section of Harvil Road, which can be seen on maps of the area dating back to the mid-eighteenth century, was closed to traffic as the new stretch opened. It will now be removed and the land under and around it will be greened with tree and shrub planting as part of HS2’s landscaping.
