Gloucestershire County Council is retendering its planned major scheme to upgrade junction 10 of the M5 to the west of Cheltenham.
The council has gone back to the market with refreshed procurement plans in the face of volatile market costs.
Council procurement chiefs had originally planned to select a contractor by this July.
Their new procurement plan will include a simplified approach to early contractor involvement and amendments to allow for rising construction costs.
A market engagement event setting out the terms of the new tender will be held on Friday 1 July via Microsoft Teams.
Under this new timetable, prequalification documents will need to be submitted by 4 August with shortlisted firms invited to bid in October.
A winning early involvement contractor will now be named in February 2023, for a project start just before the end of next year.
