Motorists have been warned to plan journeys in advance as roadworks take place on the Erskine Bridge.

Cable works will be carried out on the crossing over the River Clyde between Renfrewshire and West Dunbartonshire this weekend.

Delays in excess of 30 minutes are expected during the work between 7am and 7pm on Saturday and Sunday.

Work to protect the long-term integrity of the supporting cable stays, a key structural component of the bridge, started three weeks ago.

They will continue for a further four weekends in the weeks ahead, with the exception of the weekend of September 30 and October 1 due to other works on the A82.

Delays of 15 minutes had originally been forecast but hold ups of up to half an hour and more have been experienced by some.

Scotland TranServ major bridges manager Peter McCann said: "We have been working in consultation with Transport Scotland, Police Scotland and the local authorities to revise the traffic management element of our works following significant delays in previous weekends.

"Lanes will now only be coned off in the immediate area of work, with the bridge reinstated to full lanes after that while we will try to move traffic management as far away from the on-slip to still allow our contractors to work as safely and efficiently as possible."

Anyone planning on using the bridge this weekend has been advised to check the Traffic Scotland Twitter page for further updates.
