Barnshaws’ curved steel post aids motorway traffic flow

UK company Barnshaws Metal Bending is supplying curved steel posts as part of a motorway sign designed to improve traffic flow on the UK’s new smart motorways. Smart motorways enable the hard shoulder to be used at peak times, creating a temporary fourth lane. Variable message signs (MS4) attached to the curved tubular steel post developed by Barnshaws display information for motorists, including when the hard shoulder is available for use.
