The actress, who plays Stella Price, finished work on the ITV show yesterday (February 19) after a night shoot.
Collins thanked fans for their support on Twitter this morning as she reflected on the end of her time as Stella.
No more Stella Price last scene last night on the cobbles so sad will miss my all my lovely friends and thank you to all my lovely fans— Michelle Collins (@missmcollins) February 20, 2014
Meanwhile, Michelle Keegan (Tina McIntyre), Debbie Rush (Anna Windass) and Collins's on-screen daughter Catherine Tyldesley (Eva Price) were among the cast members who tweeted about her departure.

Stella's Coronation Street exit scenes will air in April, but show bosses have warned that her final storyline will be low-key.
Producer Stuart Blackburn said last month: "It's a very quiet exit because we've had so many big ones and there are massive ones coming up.
"It's an exit where she's trying to do the right thing by Leanne. There's a space and time where her exit might help Leanne. There's also a sense of Stella looking at Gloria and her lust for life. She's also looking at Eva who's with Jason. She thinks, 'I'm not dead yet - I'm only 50 and there's a whole world out there!'
"Hopefully it's genuine, moving, truthful and leaves the door open. But mostly Stella thinks if she goes, Leanne can get on with whatever she's getting on with - but what that is I'm not going to say!"
Collins joined Coronation Street in mid-2011. She had previously been best known for her role as Cindy Beale in EastEnders.
The actress's next project will be the release of her autobiography From Walford to Weatherfield on April 3.
