Highways England has spent £800,000 improving a cycle path which links Bishop's Stortford to Stansted Airport carrying cyclists safely over the busy M11.
It means anyone cycling to and from the airport can avoid having to use the main multi-lane roundabout to get to there.
The project includes new signs as well as some resurfacing work and adding extra barriers and fences.
The cost of the upgrade was part of an £11 million improvement scheme for the M11.
