Major roadworks on the M8 are set to cause major problems for people driving to and from Glasgow Airport.
The M8 is the busiest motorway in Scotland
Traffic restrictions will be in place from Friday for 12 weeks as work is carried out on the White Cart Viaduct bridge near Paisley.
About 80,000 drivers use this stretch of motorway every day. One in 10 of them goes to or departs the airport.
The work will mean a contraflow and a 40 mph speed limit between the Arkleston and St James junctions.
Speed cameras will also be in place during the £3.8m project to replace parapets and lighting columns.
Amey, the company which maintains the motorway, said delays were likely, particularly in the first few days.
Strathclyde Police are advising football fans to plan ahead for this Sunday's Old Firm clash at Ibrox, which kicks off at 1230 GMT.
Glasgow Taxis said passengers should expect higher fares and advised those travelling to and from the airport to leave more time for their journey.
The RAC motoring organisation also said alternative routes were likely to be crowded and that commuters should consider switching to public transport, working from home or travelling at off-peak times.
