IMO, the only way the council will rescind these closures will be from pressure from either TFL (e.g. from a material increase in the time it takes the 37 to get through East Dulwich) or from the emergency services. Recall the experimental road closures around Loughborough Junction in 2015 were ultimately killed off by a formal objection by the London Fire Brigade (Brixton Fire Station is stones throw from Coldharbour Lane which bore the brunt of the LJ closures - more here https://www.brixtonbuzz.com/2015/11/lambeth-council-u-turn-on-the-loughborough-junction-road-closures-sees-loughborough-road-reopening/). As a regular user of the 37 service to get to the Everyone Active Swimming Pool off Goose Green I?ll certainly be making TFL aware of any decline in service levels (see link here: https://tfl.gov.uk/help-and-contact/contact-us-about-buses) and would urge others (if warranted, obviously) to do the same.
