(KNZA)--A Brown County bridge project moves forward.

The Brown County Commission Monday approved awarding the contract for replacement of bridge south of Fairview to Dondlinger and Sons Construction, of Wichita, in the amount of $542,692.

It was among two bids received after the project was re-bid.

The bid came in about $50,000 lower than the original bid.

Project engineer Brady Hedstrom with BG Consultants said the location of transmission lines near the bridge site drove up costs and limited the number of bidders.

A grant will fund up to $570,000 of the total project cost, with the county responsible for anything over that amount. County Road and Bridge secretary Tami Lehmkuhl said the county's share is estimated to be about $115,000, which includes the majority of the construction engineering cost.

A construction start date hasn't been announced, but Hedstrom said the contractor must begin construction no later than May 5th.
