About this bus gate
Buses and nothing else. Buckinghamshire Council confirmed that Castle Street is a bus gate, that it operates at all times, and that only buses are permitted to drive through it — taxis are not exempt here, unlike on Corporation Street a few streets away.
A penalty is £70, halved to £35 if you pay within 21 days. None of this appears on the council’s website; it comes from its written answer to a Freedom of Information request.

Frequently asked questions
What are the operating times of the Castle Street bus gate?
The Castle Street Bus Gate in High Wycombe operates at all times. There is no time of day when general traffic may use it.
How much is the fine for driving through the Castle Street bus gate?
Buckinghamshire Council issues a Penalty Charge Notice of £70, reduced to £35 if paid within 21 days. There are no penalty points — it is a civil penalty.
Who is allowed to use the Castle Street bus gate?
Buses are permitted. Not permitted: cars, vans, lorries, motorcycles and taxis and private hire vehicles.
Can I appeal a PCN from the Castle Street bus gate?
Yes, and it costs nothing. Make formal representations to Buckinghamshire Council first — the authority that issued the PCN has to consider them before it can enforce the penalty. If Buckinghamshire Council rejects them it must issue a Notice of Rejection, and you can then appeal free to the Traffic Penalty Tribunal. Its adjudicators are lawyers independent of the enforcing authority, and their decision is binding on both sides. This bus gate operates 24 hours, so "I was outside the operating times" is not open to you — the grounds that win here are that your vehicle was exempt, that the details on the PCN are wrong, or that the approach signage did not give enough warning before the point of no return. Note that paying the £35 discounted rate accepts liability and closes the case, so challenge before you pay.
