Richmond Council say
"a signalised PUFFIN crossing with pedestrian countdown outside number 182 Kew Road (previously outside 180) Footway widening both sides of Kew Road. We have attempted to minimise the impact on the cycle lanes by introducing long tapers and following existing extended footways where possible. The kerb widening is essential to ensure sightlines to the signal heads past the many street trees."
We suggested cranked supports for the signals to avoid the loss of cycle lanes but they claim TFL disapproval.
