Now in an unusual step for a major civils project the council is going back to the market to retender the Lake Lothing Third Crossing project.
Sources said BAM Nuttall would be free to rebid the road crossing against a new field of bidders if it chooses.
BAM has been working up designs and costings since being awarded preferred bidder on the project 12 months ago.
But it is understood the project has surpassed the council’s budget forcing it to decided to retest market pricing.
Councillor Matthew Hicks, leader of Suffolk County Council, said: “It is my responsibility as leader of the Council, to ensure that we get the best possible value for the Suffolk taxpayer.
“We will achieve this by completing the comprehensive tender process.
“I look forward to reviewing the applications to build this bridge, which will make an incredible difference to Lowestoft and the eastern region.”
The decision will be a blow to BAM Nuttall which already has strong links to the region, having worked on projects such as Great Yarmouth Flood Alleviation Scheme and ABP Ipswich Quay Works.
An invitation to tender is expected in mid-November with the council planning a market engagement event to be held in Lowestoft on 30 October.
The new crossing will be a multi-span bridge which includes a rolling bascule opening section, a section which will span the existing East Suffolk Line on the north side of the lake.
The new bridge will have a 12m air draft height which will enable smaller vessels to pass underneath without an opening.
