The freight industry has repeated calls for Commonwealth Games organisers to confirm details about the route network within the next 50 days to help minimise disruption to deliveries during the event.

The Freight Transport Association (FTA) said its members need to know of any access restrictions so they can plan how best to carry out deliveries to Games venues and associated destinations, as well as shops, restaurants and offices in the city.

It warned preparations for freight deliveries during the Games are far behind those made ahead of the London Olympics in 2012.

The FTA, which first asked for details more than a month ago, has called for full details of affected routes before its conference on May 13, when it said delegates will expect answers.

Chris MacRae, FTA's head of policy for Scotland, said: "The freight and logistics industry will play a huge part in helping to deliver essential food, drink and supplies not only to the Games venues themselves but also to the residents and businesses of the city. In order to do so, it is vital to prepare well ahead.

"At the equivalent stage ahead of the Olympics in 2012, the games route network was known in detail and a working group had met several times."

He said that once the details are received, preparations may have to be made in a rush, potentially hampering efforts by logistics businesses to avoid the disruption caused by the Games.

A Glasgow 2014 spokesman said it was working with key partners to ensure residents and businesses were prepared for the event.

He added: "Glasgow 2014 holds regular discussions with freight organisations and a specific freight forum has been established in association with the FTA, which was held earlier this month. We are also attending the FTA meeting in May and will work closely with them to help with their planning."
