Holmbush Interchange is the beginning of the Brighton and Hove bypass.
The junction officially only has access from the West, with Westbound off and Eastbound on slip roads. Both the slip roads are shown to be the A270 and connect with the old A27 (now A270 and Unclassified) at a large roundabout.
To the south of the roundabout there is a West Sussex Fire and Rescue facility, for this to have quick connections to Southwick Tunnel, Shoreham Airport and in general everywhere there are three additional slip roads onto and off of the A27.
Eastbound on slip most Eastern
On the flyover which the eastbound off uses there is a seperate carriageway being an S1 which provides access to a farm and riding school, however in addition to this there is also a small and short on-slip road for Eastbound. This is protected by an unlocked gate with a sign saying emergency access only, however this gate is normally left open and there is nothing stopping a normal person from using it. This does involve tight bends so larger fire vehicles are unable to use this.
Eastbound on slip most Western
For larger vehicles there is another connection onto the Eastbound carriageway, however this involves closing or stopping traffic on the westbound carriageway as it is at surface level. It uses the westbound slip road but at the end there is a gate which can be opened to allow vehicles to directly access the eastbound carriageway at surface level after crossing the westbound. In the event that a fire vehicle needs to access Southwick tunnel there should be no traffic westbound due to the tunnel being just a KM up the road.
When heading westbound, just after passing under the flyover there is a short off slip road off, again guarded by a gate. This then follows up an S1 where it reaches the main off slip road just before getting to the roundabout.
