Pre LTN estimated hourly traffic flows on weekdays from 4PM to 7PM. Note the purple sections within the LTN and on boundary roads. I have counted sometimes 300+ motor vehicles going through what was the Valley Road roundabout (at the jnct with Gleneldon Rd) in a 15-minute period.

What are these objects which were seen today within the #A23StreathamHillWorks area?

Today's Standard reveals the average bus speed in London falls below 9mph. Key factors to blame, according to bus operators, include road narrowings, roadworks, cycle lanes and low-traffic neighbourhoods. https://t.co/63p1s3DqRc

@GreenPartyScott @Lambethgp @brixtonbuzz @BrixtonBlog @BrixtonFoodbank @heartstreatham @instreatham @streathamaction @hernehillforum @greenparty_gh @SocStreatham @streathamstuff Hello Scott, re your call (first point) for cleaner air across the borough, can I ask what is your policy and Lambeth Green's policy on LTNs? I ask because LTN impacts - pollution and otherwise - aren't straightforward and because I've never been clear on where the Greens stand.

- One ran from Balham to Norbury, terminating ten stops early (rather than continuing to Pollards Hill) and turned around for the return journey. What caused the disruption? Was it the long delays experienced by services travelling along Thornton Avenue and Sternhold Avenue?

For a report on the #255 bus service referred to in the previous post see https://t.co/ENwSagroyt.

... - Three skipped the seven stops from Balham and started at Streatham Hill Station (and one of these terminated four stops later at Becmead Avenue); ...

Of the five services scheduled (so far as I can make out) to pass through Thornton Avenue and Sternhold Avenue closest to 5PM, it appears that: - One was diverted down Bedford Hill to St. Leonard’s Church (skipping 11 stops and the section through Streatham Hill); ...

What happened to southbound #255 bus services during the evening rush hour of Friday 28 November? Some comments on and screenshots of the journeys with timings follow. See the ALT-texts of the screenshots for further details. Data source: https://t.co/iAkUkJcxjr...

... and on Friday 28/11/25 the times for the same set of services were 23, 13, 23 and 20 minutes. Meanwhile services for the #255 bus which shares the same route along Sternhold Avenue to Streatham Hill station were in disarray...

... and the journey times today (Thursday 27/11/25) for the same services were 15, 22, 21 and 23 minutes. Something I noticed is that it was possible to exit from Ardwell Road onto SHR. There was a sign saying the road is closed but no physical barriers to stop the exit.

And today's (Wednesday 26/11/25) timings for the same services: 17, 23, 22 and 20 minutes.

AGM & Public Meeting on Crime & Community Safety 13 Jan 2026 with @LambethMPS @Dunraven_School . All welcome. Nominations for the 2026-7 Committee welcome.

Today's timings for the same services were 16, 17, 16 and 17 minutes. So: better but still not great.

Evening rush hour journey times along Thornton Avenue and Sternhold Avenue have often been bad since the Streatham Hill A23 works started. Since stage 2 of the works began on Sunday 16 November, the times seem to have worsened.

Yesterday, during the evening rush hour, four successive #50 bus services took 29, 24, 24 and 20 minutes to travel the two stops from the New Park Road stop to the Streatham Hill station stop. This is against a scheduled 6 minutes. Data + screenshots from https://t.co/iAkUkJd58Z.

I wished I'd had input into this... There are, I think, significant points that could have been made on how LTN schemes are assessed. Why don't the West Dulwich people engage?

Streatham High Rd traffic delays to last up to 6 weeks while @CappaghGroup does deep sewer works for @thameswater at the junction with Prentis Rd. closing one carriageway. Shitshow & on top of @TfL works in Streatham Hill. Expect severe delays

... If a bus journey is curtailed then less of a service is provided. The same bus may also start a return journey, not from its scheduled start point but from several stops on, also (a second time) providing less of a service.

... 2. I noticed on earlier days (10/10 and 13/10) that #50 buses which have a much longer total journey time than the #255 (1hr 28 mins vs. 48 mins) apparently had curtailed journeys, stopping four stops before the scheduled final stop. Were these consequences of earlier delays?

ADDENDUM: 1. I tracked a vehicle, a black Ford Transit van on 17 Oct, travelling south along Streatham Hill from just past the A23/A205 junction to over the Streatham Hill junction (maybe 500-600m). It took 13 minutes, from 16:54 to 17:07...
