More mobile cameras are being brought in to catch drivers who speed through roadworks.

The Sussex Speed Camera Safety Partnership (SSCP) has confirmed cameras will be used on the Adur flyover where speed limits have been cut to 40mph while £1.5 million bridge-strengthening work continues until June.

The partnership says hundreds of drivers could attract £60 fines after a report last week showed more than 12,500 motorists were snapped speeding at road works on the same road a few miles east at Falmer.

The Argus reported last Tuesday £750,000 in fines was collected during the six months it took to build a £1 million subway for Sussex University students at Falmer.

Fine revenue for all speed and traffic light cameras for the year in Sussex amounted to £3,772,800 and while most of the cash came back to Sussex for more cameras, £1.5 million was kept by the Transport Department and the Treasury. This has fuelled criticism that speed cameras are merely moneymaking machines for the Government.

One camera protest group is planning a "go slow" on the M4 later this month and to put banners over motorway bridges.

Angry drivers caught by the Falmer cameras contacted The Argus. Some claimed the cameras were not properly signposted.

Emma Rogers, communications manager for the SSCP, said: "Hopefully, no speeding tickets will be issued but judging by what happened at Falmer, that is unlikely.

"Falmer showed drivers simply were not paying attention to warning signs and it can only mean they switched off, which is scary."

Ms Rogers said speed cameras at Falmer were well signposted, even though there was no legal requirement to do so.

She added serious injury crashes and deaths fell by 31 per cent at fixed camera sites in Sussex during the year, with a 16 per cent reduction at mobile sites.

The percentage of drivers and riders travelling above the limit before cameras were installed was 52 and that dropped to 27 per cent - four per cent less than the previous year.

Serious injuries and deaths dropped by 69 per cent at traffic lights with cameras, while slight injuries fell 80 per cent.
