For interest, from the 1940's – the Middlesex County Council's High Street widening proposals that were responsible for Brentford's pre-war and onwards degradation.
Note that site plot 'G' was then occupied by the Gas Accumulator Co Ltd. More detail of then existing buildings can be seen in this plan of the pre-widening High Street amongst the scheme's paperwork -
Off topic, but it is interesting to see that even at this late period, the High Street bifurcates at the western end as it approaches the Brent, with the southern line that which remains, heading over the bridge, while the northern branch here still survives, swerving as it were to reach where the Roman road entered the artificial ford crossing they had created.
The two means of crossing the Brent here existed for centuries; at one point only pedestrians were allowed to use the bridge, and all wheeled vehicles had to use the ford. Most people could use the bridge for free, but Jews had to pay a toll.
