BAM Nuttall has joined the MGL consortium to replace Galliford Try Investments.
A year-long bidding process is currently underway with a winner due to be announced next spring.
Steve Nicholson, Mersey Gateway Project Director, said: “Changes to consortiums on projects of this scale are not unusual and the fact that a replacement partner has joined the consortium shows there is a high level of interest in delivering this project.
“The procurement timetable will continue as planned and we anticipate selecting a preferred bidder in spring next year.”
