The Department of Main Roads says more than $500 million in flood works has been completed so far in central Queensland.
Regional director Terry Hill says crews are back at work and hope to have the Yeppen bridge completed by August this year.
He says the total flood reconstruction bill for central Queensland will reach $900 million by Christmas.
"There's 42 reconstruction sites across central Queensland that are operational at this stage," he said.
"On the Bruce Highway there's 22 work sites and there's about 700 people working between Miriam Vale and up to St Lawrence, just in this section in central Queensland, to reconstruct the damage that was caused in those flood events."
