An investigation by The Argus has uncovered the latest reason being blamed for a series of lorries getting stuck under a low bridge – a white line designed to direct cyclists.

We sent a reporter to discover what has been happening at the bridge carrying Brighton railway station’s concourse over Trafalgar Street.

We tested a theory that satnavs were responsible but the problem appears to be down to white line road markings.

The problem is believed to stem from recent roadworks which have installed a contraflow cycle lane under the bridge.

Traffic experts from Brighton and Hove City Council have investigated the issue and will meet Sussex Police this week to try to work out a solution.

Roger French, managing director of the Brighton and Hove Bus and Coach Company, said he was convinced white line markings painted as part of the works were the real problem.

He said the white line to guide cyclists straight on, so they know they are allowed to go the wrong way up the street, was confusing some drivers.

They assumed they should be going straight instead of left, and missed the no entry sign in the process.

Cycling campaigner Ian Davey, who represents St Peter’s and North Laine on Brighton and Hove City Council, said: “That bike lane was much needed and has been a godsend for cyclists trying to reach the station but maybe some more improvements are needed.” In the past month, two lorries and a coach of school children have driven the wrong way up the one-way street and become trapped under the bridge.
