There's been a gap in the Teddington area for quite some time. The strip to the east of Bushy Park as far as the Thames was conspicuously incomplete.
Last Sunday the weather was really nice (for January) and so I made a 50Km cycle trip to fill in this area. All of Teddington to the south of the High Street is now complete. It also fully connects my area to the mapping that was done the other side of the river in Kingston as part of the first Fill The Gap mapping party.
So now there is a complete swathe of mapping from central London out to the M25 at Byfleet. A bit of infilling in the Surbiton / New Malden area to the south and Hanworth / Twickenham to the north would complete the whole section between the M3 and A3 right out to the M25.
