Engineers scrambled to assess the condition of the carriageway on the Forth Road Bridge yesterday following spillage of hydraulic fluids on its surface.
Long delays faced drivers on the bridge last night after a lorry spilled the fluid along the road surface at around 1.40pm. The spill covered most of the 2.5km length of the bridge’s northbound carriageway.
Northbound traffic was restricted to a single lane for most of the afternoon leading to very long delays throughout the evening peak period.
Specialist road cleaning equipment was brought in to make the carriageway safe and to prevent the hydraulic fluid causing damage to the bridge’s mastic asphalt surfacing. Engineers then had to assess the condition of the carriageway and skid tests were carried out before the carriageway could be reopened at approximately 7.45pm.
The bridge authority planned to close the affected lane again later in the evening once traffic has cleared, to clear away any last traces of the hydraulic fluid.
