Coronation Street is to extend its weekly run from five episodes to six by broadcasting a double bill on Wednesday nights.
The first extra show will air on September 20 at 8.30pm, and the show will mark the occasion with the double wedding of Aidan and Eva, and Jenny and Johnny.
But as is traditional for soap nuptials, not everything will go according to plan, as Aidan Connor (Shayne Ward) confesses his affair with Maria to fiancée Eva Price (Catherine Tyldesley) on their big day.
Plans will also go askew for Jenny Bradley (Sally Ann Matthews) and Johnny Connor (Richard Hawley) when ailing Rita's health takes a turn for the worse, forcing them to stall their plans and rush to the hospital.
Plans to extend the ITV soap's billing were originally announced last year, but an official date wasn't confirmed.
"We're thrilled to be launching our extra weekly episode on Wednesday, September 20, a he heart of a truly unmissable week of heart-stopping drama, heart-breaking emotion and heart-warming comedy," said executive producer Kieran Roberts.
He explained that plans for the new shows have taken more than a year to prepare and included building an extension to the show's Manchester-based set, which viewers will see next year.
Teasing further twists and turns to come in some of the show's most dramatic storylines this month, series producer Kate Oates told how Michelle Connor (Kym Marsh) will soon discover the horrifying truth of her stalker's identity: her ex-boyfriend Will.
Comedian Jim Moir - better known by his stage name Vic Reeves - will also step into the ITV soap as newcomer Colin Callen. As the organiser of Norris and Mary Coyle's Mr and Mrs Quiz competition, he soon ruffles feathers.
Bethany Platt's harrowing grooming storyline will also continue through autumn as the teenager (Lucy Fallon) faces the trial of her abuser Nathan Curtis (Chris Harper).
"We are going to see if she makes it to court," said Oates. "It's a huge deal for a girl in her position to face.
"We still have the issue of Nathan's friend, Mel, who he had brain-washed, who will try to stop Bethany going to court," she added. "Will Nathan ever face justice?"
