Defective drains close BCIA winning Bingley relief road


SECTIONS OF the award winning £49.5M Bingley relief road are to close for almost two weeks to rectify a drainage defect, the Highways Agency confirmed this week.

Contractor Amec was this week digging up the southbound carriageway after it was discovered that kerbside drainage units along 20m to 30m were incorrectly installed.

Last month the road scooped the prestigious Prime Minister's Award at NCE's British Construction Industry Awards.

The units are supposed to contain drainage channels whose increasing diameter creates a downward slope, taking run off into the sewerage system.

But it is understood that Amec was only able to source units with same internal diameter. As a result water is collecting in a silt trap rather than draining after heavy rain. This leaves the stretch prone to flooding.

Amec has agreed to spend £30,000 to £50,000 installing an additional drainage pipe across the southbound carriageway over the next two weeks.

This will drain water into a catch pit in the central reservation.

The problem first emerged during heavy rainfall in August.

The Highways Agency has decided to act this week before winter, when standing surface water could freeze, putting motorists in danger.

The Agency has apologised for the disruption.

'The remedial drainage works are an isolated issue which does not in any way call into question the basis for winning the British Construction Industry Award, which the Agency is justifiably proud of, ' it said in an official statement.
