The organisers of the Glasgow Commonwealth Games have said they have released details regarding the Games Route Network (GRN) but the Freight Transport Association has said its members still require more information.

A GRN is a requirement for any city chosen to host the Games and will ensure 6,500 athletes and officials are able to get to venues across the City of Glasgow and in neighbouring towns over its 11 day span. It comes at the cost of £4.5m and sees upgrades to CCTV and traffic signals and signage.

It will also mean lane restrictions as well as temporary turning and kerbside restrictions. The GRN will be phased-in from 8 July, becoming fully operational from 21 July.

Michael Renshaw, Glasgow 2014 director of transport, said: “The city will be bustling with activity come Games time and with that, our transport networks will be busier than usual. The GRN is essential to make sure athletes and officials reach events on time,” he added.

“Glasgow and the surrounding area may have to operate differently but by working together to make sure we are informed, prepared and ready, we can deliver an outstanding Games that everyone can enjoy.”

Last week the FTA criticised the lack of information flowing to operators from the Games’ organisers and issued a 50-day ultimatum asking for published details on routes, delivery restrictions and security measures, ahead of its 13 May logistics conference about the event.

FTA head of policy for Scotland Chris MacRae said that while he did not want to draw comparisons with London 2012, as Glasgow was a very different city, “by 3 April 2012 the GRN was known and venue security accreditation procedures were known”.

He added that the current GRN was only a map without any further details on actual time and postcode restrictions: “What we have got is better than nothing and we will work around it. But we need to get the other information coming through as soon as possible.”
