Riverview bridge several weeks from completion

It could be two weeks before the Riverview bridge is poured across the west fork of the Des Moines River, the Emmet County Board of Supervisors heard Tuesday.

The bridge is located south of Estherville and east of Highway 4 on 200th Street.

The project has a late start date of May 5 with a completion deadline of 100 working days, which would have been last Friday. A $1,000 fine applies for each day the project is late.

Dan Burton, assistant to county engineer Roger Patocka, said the bridge will likely be poured the end of next week or into the following week.

The supervisors awarded the project to Graves Construction of Spencer, which submitted the low bid of $889,642.75.

The next lowest bid came from Christensen Brothers, Inc. of $986,090.75. The high bid came from Minnowa Construction, Inc of $1,081,053.35.

Patocka originally estimated the bridge would cost $1,040,000.

Even if the bridge is poured last next week or the following, Patocka said it would take seven days for the concrete to cure. Burton said the 580 cubic yards could be poured at the rate of 60-90 yards an hour, with an average of around 80.

Patoka said work after that would include approaches and guardrail installation and painting.

In other business Tuesday, Patocka said crews were blading, ditch cleaning, edge rutting, building up roads, seeding and doing other projects.

The board approved maintenance agreements with Dolliver and Gruver for snow plowing at $105 an hour. Patocka said the county plows when requested.

Patocka said there could be a change in the PSI rating of a natural gas pipeline on the county highway right of way between Armstrong and State Line Coop's Halfa feed mill.

Patocka said Alliant Energy had said future gas usage could change the line from 50 pounds PSI to 100. The line would extend from south of the Armstrong Cemetery to the Catholic Cemetery then 1.5 miles west to N60 and from there to Halfa, along with fiber optic cable.

"I think we're going to see more natural gas lines the way the energy situation is shaping up," Patocka observed.
