Abstract:		 An archaeological watching brief was conducted by Pre-Construct Archaeology Limited on geotechnical ground investigations undertaken in 2013 and 2014 in advance of the replacement of Power Road Bridge, Gunnersbury, London Borough of Hounslow. The work was commissioned by Ramboll UK Limited on behalf of Transport for London. The bridge carries the A406 (North Circular) over the railway line from Brentford to South Acton and was built between 1920 and 1935 replacing an earlier bridge constructed 1853. The project was designed to advise relevant parties of the potential heritage significance of the site in order to inform decisions concerning the need for archaeological mitigation. At the south end of the groundworks area, the A406 lies at a height of c.11m aOD, level with the surrounding area. The road rises gradually to the north on an embankment as it approaches the bridge (at c.15m aOD) over the railway line. To the north of the railway line, the embanked road drops gradually to the north until it is again level with the surrounding surface at c.11m aOD. The watching brief established that the embankment carrying A406 to the north and south of the bridge over the railway line overlies 'Brickearth'. The embankment, which is up to c.4m in height, was constructed in the mid 19th or early 20th century and may seal potential archaeological deposits which overlie or are cut into the 'Brickearth'. No archaeological deposits or artefacts were found during the course of the watching brief which mainly uncovered embankment and later deposits.
