A section of Worth Way in Crawley Down will be closed for up to four weeks whilst surface improvement works are carried out.
The work will commence in the last week of July, as to not impact on the safe route to school that Worth Way provides for many pupils in the area.
The route is situated between Crawley Down and East Grinstead with the closure starting by Crawley Down Pond and stopping at Gullege.
An alternate route using public footpaths is available and will be signposted on-site.
Cyclists and equestrians may follow another alternate route using the public bridleway but should be aware this involves road-riding so may not be suitable for children.
The surfacing will complete previous work carried out on the road and result in a smoother, well-drained surface from Crawley Down through to East Grinstead train station, improving the route for all users.
West Sussex County Council’s Cabinet Member for Environment, Deborah Urquhart, said: “We apologise for any inconvenience whilst the improvements are carried out, however they will secure a much improved surface for many years to come.”
