On Monday 10 January construction began on upgrades to a stretch of public bridleway and active travel route in Long Wittenham, Oxfordshire.

Can't say I use the route between Reading and Didcot, but Oxfordshire County Council has been doing quite a bit to improve cycle routes in the Didcot area. The Hanson Way between Didcot and Oxford is much improved. They have also improved the route(s) between Didcot and Harwell/Chilton, although I have not been that way since the start of Covid.
