Emergency work being done on the Forth Road bridge that weekend. This is what it says on the Traffic Scotland website..............
Forth Road Bridge - Long Delays Expected Saturday 10 and Sunday 11 March
Motorists are warned to expect long delays at the Forth Road Bridge on the mornings of Saturday 10 and Sunday 11 March. Traffic will be restricted to a single lane in both directions while repair work is carried out on the cables above the carriageway.
Restrictions will be in place from 03:00 to 12:00 noon on the morning of both Saturday 10 and Sunday 11 March. Significant queues are expected to build up after 09:00, particularly on Saturday.
Pedestrians and cyclists will be able to cross the bridge using the west footpath/cycleway.
The work has been scheduled at short notice after an inspection identified new damage to nuts on the bolts that hold the vertical hanger ropes to the bridge’s main suspension cables. The hanger ropes loop around metal castings which are bolted to the cables by 35mm diameter steel bolts, each with a nut at either end. There are 944 of these bolts.
Cracks had previously been found in a small number of the nuts during a routine inspection in 2007. These nuts were replaced and the bridge authority stated its intention to replace all of the nuts over time as and when access and resources permitted.
