“They picked up where they left off today to complete the installation.”
The new railing sections were placed on blocks last week adjacent to where they will be fixed to the bridge.
Mr Hadfield said depending on how the work went today, this could be the last lane closure needed as part of the project to widen the bridge.
“As with previous closures we have had traffic controllers in place to manage traffic while the downstream lane was closed.”
Motorists were again advised to consider using an alternative route or allow an extra 10 minutes for their journey.
“We’d again like to thank the community for its patience and understanding throughout the closures.”
The bridge improvement project remains on track for completion next month.
