A project to widen Highway 91 in Riverside will cost between $17 million and $21 million more than initially estimated because the job’s low bidder has been disqualified.
Officials opened bids Dec. 8 for the project to add car pool lanes along six miles of east- and westbound Highway 91 from Adams Street to the 60/91/215 interchange. Since then, contractors and Caltrans officials have traded letters and worked to resolve a host of issues ranging from estimates of how long the job would take to not including enough minority contractors in the process. A Southern California Congresswoman also has weighed in on behalf of companies in her district, according to letters associated with the project.
