Motorists have been warned to expect three months of delays on the M8, one of Scotland's busiest motorways.
With work on one major project completed, another is set to begin
Work is due to begin in two weeks on a £4m project to upgrade the White Cart Viaduct close to Glasgow Airport.
Amey, the company which maintains the motorway, said delays were likely, particularly in the first few days.
Glasgow Taxis said passengers should expect higher fares and advised those travelling to and from the airport to leave more time for their journey.
Bill McIntosh, secretary of Glasgow Taxis Ltd, said the work would cause considerable disruption.
"Our drivers will try to find alternative ways around the gridlock but unfortunately other drivers may be doing the same," he said.
"We have to warn passengers that an increase in journey distance may mean an increase in fares.
"I would urge all travellers to give themselves extra time for their journey but we can assure passengers that all taxi drivers will be co-operating with the police and the relevant authorities to ensure that the disruption is minimised."
The RAC motoring organisation also said alternative routes were likely to be crowded and advised commuters to consider switching to public transport, working from home or travelling at off-peak times.
Routes to and from Glasgow Airport are likely to be crowded
The project to replace the parapets and lighting columns is due to start on 10 February and last for 12 weeks.
The work will mean a contraflow being put in place and a 40 mph speed limit between the Arkleston and St James junctions.
Jim Gilmour from engineering firm Amey: "Sadly we do anticipate significant disruption to traffic, but we're hoping with the help of motorists that will settle down over the early days and people will fit into a routine during the 12-week duration of the work.
"We've done everything to analyse the impact on congestion by traffic modelling, but clearly there will be queues."
The announcement came as work was completed on another major phase of roadworks on the motorway.
The Stobcross on-ramp to the Kingston Bridge was closed for almost a year while an £11m programme of repairs and strengthening work was carried out.
