Road hole 'caused by air pocket'

The collapse of one of Belfast's busiest roads was caused by an air pocket rising to the surface, an NI Water spokesman has said.

Bill Gowdy said the rupture in Cromac Street damaged an old Victorian sewer about four metres under the road.

He said the air pocket was probably disturbed a year ago during work on the Belfast Sewers Project.

It will take a week to repair the road, and significant rush-hour traffic disruption is expected on Monday.

The damage to the road was discovered early on Saturday.

The tarmac mostly stayed intact, but a 15 square metre hole emerged underneath the road.

Mr Gowdy said the air pocket was an "exceptional event" caused by Belfast's "unique clay geology".

The new storm-water tunnel built as part of the Belfast Sewers Project lies 15 metres beneath the surface and was not damaged.

The project remains on course to begin operating before the end of the year, said Mr Gowdy.

No infrastructure cabling was damaged as the road buckled.

Meanwhile, motorists driving into Belfast city centre on Monday have been warned to expect significant traffic disruption.

Drivers coming in from the east and south of the city will be worst affected.

The Roads Service have put in a number of signposted diversion routes while Cromac Street remains closed:
