"Lower Richmond Road has a near permanet queue heading towards Chiswick Bridge, the general question is how long it is. So of course traffic will barely increase." You are factually incorrect to assert that a longer queue will not be registered by a traffic counter. If more vehicles from a longer queue pass the counter, whatever their speed, they will be counted.DfT traffic counts on each of the Bridges and Lower Richmond Road have hardly changed between 2018 and 2019. That indicates that journeys on Hammersmith Bridge have not simply been transferred to the neighbouring bridges. If traffic has not been significantly transferred, it's difficult to see how that could drive an increase in local congestion. There is in fact a full set of manual counts for one route that we might expect to be affected by the closure, Station Road in Barnes that forms part on an EW pathway for local traffic between Mortlake and Putney. Any significant increase in local traffic due to the closure hold be seen in the total traffic counts and a change in the pattern though the day as congestion took longer to clear. Comparing the change for every year compared to the previous year, 2019 had both the smallest average change and what's more the smallest change across all the hours of the day compared to the previous ten years, as far back as the data goes.None of this data can possibly be construed as indicating a significant increase in congestion due to the closure, but I rather suspect that won't stop you trying to argue otherwise, while offering no data to support your case.
