New Forth Road crossing reaches 200m in three months
Scottish Transport Minister Keith Brown has described the progress of the new Queensferry Crossing between Lothian and Fife as “remarkable”. T e bridge, which runs alongside the existing Forth Road
Bridge and Forth Bridge (for rail) is the biggest transport infrastructure project in Scotland for a generation. During a visit to monitor progress Mr Brown said that
the operation is even more spectacular when you view it up close. “In just three months since the fi rst push launch,
Vysionics ITS to deliver Europe’s longest average speed enforcement system
the viaduct has been assembled and pushed out across the fi rst two piers of the bridge” he said, “it’s great credit to contractors FCBC and the 110-strong team… to have taken such great strides in such a short space of time”. T e viaduct deck arrives by road in 33 metre segments
weighing 72 tonnes from Cleveland Bridge in Darlington. Each section is then fabricated on site into one long con- tinuous section of 543 metres. T e preparation of the steel- work currently takes up most of the company’s capacity.
Ritherdon unveil new crash-resistant cabinet
Installation of roadside technology could be a great deal cheaper in the future, thanks to a new innovation by Lancashire- based cabinet and control panel manufacturer Ritherdon. Its new Passively Safe Cabinet
Transport Scotland has appointed Vysionics ITS to deliver around 140 miles (220km) of average speed enforcement on the A9 corri- dor north of the Central Belt. T e company’s SPEC3
average speed cameras will be used on the road between Dunblane and Inverness. Part of the overall strategy will
be to increase the HGV speed limit to 50 mph on the single carriageway sections between Perth and Inverness, while the camera network will also monitor the dual carriageway
smartHIGHWAYS Vol 2 No 1
section from Dunblane to Perth. Well-signed cameras
will be installed at inter- vals of fi ve-to-seven km. T e cameras can operate in
complete darkness, thanks to the use of infra-red illumina- tion, which is key because of rules against lighting through the Cairngorm National Park. Off ence data will be collected
at the roadside and commu- nicated wirelessly back to a remote central server, allowing for enforcement links to be fl ex- ibly managed from the Safety Camera Partnership back offi ce.
has been built to safely break away aſt er a vehicle collision of up to 100km/h (approx 60mph), remov- ing the need for a crash barrier to be installed around the cabinet. T e roadside technology
is housed inside the cabinet which is then attached to a plinth on the road, with the wiring connected through a “pole plug” in the plinth. If the cabinet is hit the housing
comes away and the pole plug connectors are easily separated. T is means that at worst the equip- ment can be rehoused in a new cabinet, or that the cabinet can just be reconnected in minutes.

and embed- ded cables in the ground are completely undamaged. T is could save as much as £20,000 in the cost of installing a crash barrier, which would make the siting of ITS equipment at the roadside much more cost-eff ective.
