Other forms: diversions
A diversion is a route round a closed road. Follow the diversion, a diversion in place, a signed diversion.
In Britain diversions are marked with yellow signs and coloured symbols, and following one for nine miles to travel four is a national experience. It also means anything that draws attention away: create a diversion. And it means an amusement or pastime: a pleasant diversion — which is the oldest sense. Note divert, and diversionary, which is used of tactics meant to distract.
Latin divertere means to turn aside — di- plus vertere, to turn. Divert, diverse and divorce all come from that turning away, and a diversion is the road version of the same move.
