|Route outline (key)|
The C705 runs south from the former B3378 in Poyle, through the industrial estates serving Heathrow Airport on Poyle Road, to the Golden Cross Roundabout, where it heads along Horton Road to the boundary with Surrey Council at the Wraysbury River. At the boundary, it becomes Surrey's D6365 for a short distance, before entering Hillingdon Council's patch very briefly, before reaching the Highways England maintained Poyle Interchange: 4 Authorities in the space of 500ft!
