A concrete defect on a bridge carrying the M9 road near Edinburgh forced the road beneath it to be closed for safety inspections to be carried out.
The B800 road was closed on Monday between the A89 and Lochend Road, just south of Kirkliston.
Pictures posted on twitter by Chris Brodley show a patch of concrete on the underside of the bridge which appears to have crumbled away, leaving some rubble on the road below.
Transport Scotland's operating company, Amey, is responsible for the bridge carrying the M9.
Tom Wallace, Amey account manager for the Scottish South East Trunk Road Unit, said: “A concrete defect has been reported on the M9 J1 northbound River Almond Bridge and traffic management has been put in place; a temporary diversion is also in place on the B800 directly below the bridge deck.
“The defect poses no risk to the travelling public, but we are treating this work as an urgent repair to ensure that these routes can be fully re-opened as soon as possible.”
A council spokeswoman confirmed the road was closed earlier while Transport Scotland worked to ensure the area was made safe.
