WORK to build a massive aerial roadway is set to bring more than a year of chaos for Glasgow drivers.

WORK to build a massive aerial roadway is set to bring more than a year of chaos for Glasgow drivers.

The viaduct is being built as part of the M74 extension and will be as high as the Kingston Bridge.

It is needed to clear the main rail line from Central Station and sweep over a huge area of the South Side.

Although work is not due to begin until next week, electronic warning signs have already been put in place near Eglinton Toll.

The diversions triggered by the construction of the Port Eglinton Viaduct will last until May next year.

Piers to carry the roadway are already in place.

Now work is beginning on the decking which will carry traffic from Pollokshaws Road and on across the rail line.

The viaduct will become one of the most prominent landmarks of the M74 project and is one of 13 bridges along the route.

Interlink M74, the construction company in charge of the £700million project, has warned that the work will cause problems for traffic in the Eglinton Street area.

The company said the first phase of diversions would start on Monday and last around six weeks.

Traffic travelling north on Eglinton Street, between Gourock Street and Cumberland Street, will be reduced to one lane with the bus lane suspended.

Vehicles travelling south between Cumberland Street and Turriff Street will also be reduced to one lane.

There will be no right turn into Kilbirnie Street and a diversion will be in place via Turriff Street, Pollokshaws Road and Devon Street.

Traffic management arrangements are also planned for Francis Street, Ritchie Street, Salkeld Street and Stromness Street, and details will be released once they are finalised.

An Interlink spokesperson said: "We apologise in advance for the impact these traffic management procedures will have but it is a key part of the work to ensure that the construction of the M74 project stays on track.

"The completion of the M74 will bring significant economic and social benefits to businesses, communities and industry in the west of Scotland.

"Completion of the vital missing link in the M74 will reduce congestion and provide new transport links for industry."
