Coming in more than $5 million under project estimates, Ames Construction was chosen as the general contractor to build an overpass across the Union Pacific tracks at State Route 347.
Based in Scottsdale, Ames has 750 days to complete the project. Its winning bid was $23.1 million.
The State Transportation Board selected the contractor at its Sept. 15 meeting in Tuba City. Because the bid was 18.5 percent under the department’s estimate of $28.3 million, it was pulled off the consent agenda for a full discussion before its approval.
