PWS Signs have completed the design, manufacture & installation of a new solar powered Low Bridge Warning system and signs for Fingal County Council at the N3 underpass near Mulhuddart in Dublin. Due to its low clearance (2.6m) there has been a long history of motorists ignoring the existing low bridge warning signage with vehicle strikes occurring regularly. There were also daily disruptions to traffic flow due to over-height vehicles having to reverse away from the bridge.
Fingal County Council commissioned PWS to design & install a solar powered Overheight Vehicle Warning system on both approaches to the underpass. The signs are activated by a solar powered Infra-Red detection stations located in advance of the underpass approaches & any vehicle in excess of the 2.6m clearance height is immediately detected by the IR station. A radio signal is sent to the signs which activates the signs to display a warning message TURN BACK NOW in both Irish & English in sync with Amber LED flashing beacons at the top of the signs.
Since going live, the signs have proven very effective in helping to prevent vehicle strikes and the ensuing traffic disruption which was a regular feature of this location.
