Steve Mason, a programme delivery manager at National Highways, urged drivers to stick to official diversion routes.
He said: “While we’re encouraged by the largely positive feedback we’ve received about last weekend’s operation, we’ve identified improvements for this weekend’s final closure.”
He said extra resources would be deployed to support work with Cumbria Police and Westmorland and Furness Council in “deterring drivers from ignoring official diversion routes”.
“There will be further temporary prohibitions and extra staffing, including at King’s Meaburn,” he added.
The bridge was demolished last weekend and the new bridge is due to be positioned during this weekend’s closure.
Disruption also affects trains on the West Coast Mainline, with buses running between Oxenholme and Carlisle and a shuttle rail diversion running on the Settle to Carlisle line between Preston and Carlisle.
