Coronation Street is to be rocked by a massive disaster which causes carnage in Weatherfield, show bosses have revealed.

Some of the show’s major characters will be killed off in the major 50th anniversary storyline in December which will see the viaduct which spans the cobbles collapsing, together with a tram crash.

Announcing the plot on ITV1’s This Morning, producer Phil Collinson said: “If you’re listening in Weatherfield, one fateful night at the beginning of December the viaduct’s going to collapse, down by the corner shop and the Kabin, and a tram is going to crash into Coronation Street.

“People are going to be injured, people are going to be killed. It’s a big, big story for us and one fateful night will play out across a whole week. Picking up the pieces of that into next year is going to be huge.

“We’ll be losing some well-known, well-loved characters. And hopefully we’ll be keeping under wraps who exactly will be going. We’ll be doing everything we can to make sure we keep that secret until it transmits.”

Phil also teased viewers about what to expect from upcoming storylines, promising that 2011 would be Tracy Barlow’s year after she returns as a full-time character.

He said Audrey Roberts would end up with a broken heart and that viewers would hear the patter of tiny feet ‘from a couple of places’ across the autumn.

The producer also revealed that the idea to cast the two sons of long-standing cast member William Roache, who plays Ken Barlow, was prompted by the actor himself.
