Background/Discussion
On December 19, 2023 bids were received by the DOT as follows:

$1,899,842.40 |
| Engineer’s Estimate (HGM) |
$1,472,457.25 |
The Iowa DOT annually makes Federal and State funds available for the purposes of rehabilitating or replacing structurally deficient or functionally obsolete bridges. The Benton Street Bridge over Indian Creek (FHWA Structure 002700) ranked high enough among other bridges in the state to qualify for participation in the program.
Highway Bridge Program funds allow for 100% of construction costs for the bridge replacement with a maximum reimbursement of $1,000,000. Engineering fees and the City’s share of construction cost will be paid with Local Option Sales Tax funds. The Council Bluffs Water Works will reimburse the City for the costs associated with the water main relocation. The total bid amount for water main items is $107,605.
During the bidding process, the project was discussed with eight qualified contractors. It was noted that there are currently a lot of bridge projects, and most were interested in bidding larger projects. This was confirmed with the single bid received. Based on this feedback, re-bidding the project will not likely result in a more favorable outcome.
The existing bridge will be replaced with a box culvert section along Indian Creek, essentially replacing two structures with one structure. A new roadway will be constructed over the box culvert.
