COLUMBUS – The Platte County Board of Supervisors voted unanimously on Tuesday to accept construction bids until March 19 for a grading and paving project on just under a mile of Third Avenue stretching south from 53rd Street to Lost Creek Parkway.
The paving project, a little longer than three-quarters of a mile of grading and 9 inches of new concrete pavement, is on the county’s one-year road improvement plan and has an estimated price tag of $900,000.
The bids received by the county will be presented to the seven-member county board at its March 20 regular meeting.
Work on the grading and paving project, according to Mark Mainelli of Lincoln-based Mainelli Wagner and Associates, the county’s highway superintendent, depends on the removal of a bridge this summer and its replacement with a concrete two-box culvert.
Potential contractors were given flexibility on setting start and completion dates to minimize closing time while the bridge is removed and replaced with a culvert, Mainelli said.
"That's why we left it open," said Mainelli.
Grading, grinding up the asphalt and packing it down as a base, pouring 9 inches of concrete and building shoulders will follow, he said.
The county's target date for completion is Sept. 30.
Mainelli has also been the county engineer since 2016.
The county bid documents require contractors to include estimated beginning and completion dates for construction.
The successful bidder on the project will be allowed 55 calendar days for completion after work at the site begins. A second phase of paving in that area will extend from Third Avenue and 53rd Street westward to 18th Avenue.
The Third Avenue and 53rd Street paving projects have both been identified as top paving priorities for the county.
With the number of residential homes along that stretch, Mainelli said, the county will do some community outreach to learn what property owners think about a project's impact on such things as landscaping and drainage.
"We'll be talking to people about their concerns," he said, adding the 53rd Street paving might need to be done in phases because of budgetary issues.
In another matter, the board voted to approve Chairman Jerry Engdahl inking the agreement for the replacement of a bridge on 445th Avenue south of Highway 22.
The estimated cost of the project has yet to be determined.
