A MAIN route into St Helens town centre closed unexpectedly on Friday to allow more work on Saints new stadium.
The Linkway East was originally planned to shut both ways for two weeks on November.
This latest closure is being blamed on delays caused to bridge works by a gas leak, a spokeswoman for St Helens said.
Prior to the closure lane restrictions had been in place for much of the past two months.
The spokeswoman added that work on the bridge needed to finished by December 9 for a season-ticket holders event.
