COMMONWEALTH Games organisers have been warned deliveries across Glasgow face disruption unless officials speed up the flow of information about traffic restrictions and road closures.
Some details were published on Tuesday, when it emerged that one of the city's busiest commuter routes would be closed during the 11-day competition.
Two sliproads on to the busy Kingston Bridge will be shut at West Street and Stobcross, forcing motorists to find alternative routes when driving from the south side to the west end.
Glasgow 2014 officials have said that the full information, including mapping, specific Games route networks and traffic management plans, will be available by the end of this month. There will also be a series of meetings and workshops for traders and access to a travel adviser.
However, Chris MacRae, head of policy for Scotland at the Freight Transport Association, said businesses needed the full parking plans and local area traffic management details as soon as possible in order to organise changes to delivery schedules and normal routes.
He said the Games would provide benefits for Glasgow, both in terms of sporting and transport legacy, and pointed to improvements which would benefit the likes of Dalmarnock railway station and the M77.
However, he added: "The Freight Transport Association and its members have become increasingly concerned about freight issues both in terms of servicing the additional demand for goods and services that the Games themselves will bring and crucially maintaining services and deliveries to businesses, shops, offices and residents within the city.
"With any event such as the Commonwealth Games there will undoubtedly be disruption due to the sheer weight of numbers, but the issue is how that disruption is managed and planned for to minimise its impacts.
"Local Area Traffic Management and Parking Plans are still not known and some will impact on very large food retail stores near to venues. Bearing in mind some of these have night-time delivery restrictions there is a circle yet to be squared on how delivery lorries access them to stock the shelves with food."
A spokesman for the organisers said: "Detailed plans for traffic management around venues in Glasgow during Games time will be made public towards the end of April and a further round of information sessions will be held in May when more specific detail around traffic, travel and parking is available.
"In addition, there are specific information sessions for businesses to help prepare for the Games. These workshops will be open to up to 20 businesses at a time and are available to businesses with at least 25 employees.
"At each workshop a travel adviser will work with the businesses to help to develop travel action plans. Further to the workshops, drop-in information sessions will be available to businesses across Glasgow in the run-up to the Games."
Officials say the route networks are a requirement of any city chosen to host the Games and will ensure that athletes and officials get to venues within 20 minutes of leaving the Athletes Village.
Stuart Patrick, of Glasgow Chamber of Commerce, which represents 2000 firms, said: "It has been trailed to us that April is the key month when we'll get all the information and we'll be very disappointed if that doesn't happen.
"We support all information being supplied as early as possible, even if that means it coming out as a drip-feed, as it lets businesses start to plan their operations during the 11 days of the Games.
"Some businesses have a longer lead time for planning than others."
