However, it also states that long sections of narrow lanes can cause difficulties for cyclists. This theory was borne out at one of the video sites in Oxford where a lane width of 3 metres led to a number of conflicts caused by drivers attempting to overtake cyclists with very little clearance. These should be backed by appropriate enforcement measures, where feasible. Lane widths between 2.75 and 3.25 metres should be avoided in most cases. Traffic signals should give cyclists sufficient opportunity to pass safely through road works, particularly where oncoming motor vehicles cannot pass without conflict.
Cyclists are unlikely to accept lengthy detours or long delays.
In such conditions some cyclists will be tempted to ride contra-flow or use the footway. Where there is cycle provision, such as cycle lanes or tracks, efforts should be made to keep these open or to provide an acceptable alternative during the road works. They should not be blocked by signs, debris, plant, etc. This can be avoided by, for instance, providing a segregated cycle lane or route away from the carriageway. This kind of provision is likely to be desirable or even essential on dual carriageways or multi-lane roads.
