A new entrance and access road into Tilgate Park in Crawley will open on Tuesday (28 July),
This will reduce the number of visitors travelling through residential streets in Tilgate.
The £1m project has seen the existing emergency access widened to become the main vehicle entrance into the park when it opens next week.
A new cycle path has also been constructed.
Other improvements include extending the main car park and introducing new disabled parking areas together with improved coach parking.
