Denton bus diversion: 12 and 12X miss coastal stops overnight from 9 November

Last updated: 9 November 2026, 09:34 GMT.

A Denton bus diversion starts tonight, Monday 9 November, changing overnight journeys on Coaster routes 12 and 12X between Newhaven and Eastbourne. Passengers using the coastal stops need to check the replacement arrangements before setting out: a bus with the usual route number will not follow its usual route through this stretch.

How the Denton bus diversion works

The operator’s current service notice attributes the change to roadworks at the A259 Denton roundabout. Eastbound buses will use New Road, the A26, A27 and A2270 towards Eastbourne. Westbound services will follow the reverse diversion and rejoin at Newhaven Station.

The notice lists the overnight window as 19:00–06:00, “between the 9th and 14th November”. Travellers planning the final overnight journey should check the live notice for the precise end of the works rather than assume a normal service has resumed.

The most useful exception is Newhaven Station: all services will still serve it. The operator separately advertises a shuttle between Seaford and Eastbourne, starting at 18:45 and running approximately every 35 minutes. Its notice does not promise a timed connection with every diverted bus, nor describe that shuttle as covering the full Newhaven–Seaford gap.

What passengers should do

• Use the operator’s journey planner for the actual date and time of travel, then read the service update alongside the suggested journey.
• If boarding between Newhaven Station and Eastbourne Station, check whether your usual stop is served by the shuttle or requires another arrangement.
• Allow for a different interchange and journey time. Do not rely on the usual coastal timetable to guarantee a connection.

For Brighton passengers returning from the eastern end of the route after work or an evening out, the important question is where to board. This is a substantial change to the overnight route, not simply a short delay at the roundabout. Other current disruption is covered in our Brighton News section.

Brighton Locals’ view

The early shuttle start is useful, but a frequency of approximately 35 minutes makes the connection details important. Our assessment is that passengers need the stop-level plan before travelling; the presence of a replacement shuttle alone does not establish that every usual journey remains straightforward.

What happens next

Check the operator’s notice again before each affected evening, particularly if the roadworks change. We will update this report if the operator confirms altered dates, additional stops or clearer connection arrangements.

The practical point: Newhaven Station remains on the route, but the usual overnight coastal stops do not.
