It’s the corner of Waterloo Bridge and The Strand so, you know, quite busy with both pedestrians and cyclists. They’ve actually widened it slightly since ^that Streetview - however it nows runs directly along the front of The Lyceum Theatre, home of The Lion King, so can be quite challenging trying get through 200 tourists taking selfies of an evening.
The other classic just by my work is this one:
Cycle lane inbetween two pavement cafes? Can’t see any problem with that…
