Alexandria’s Broadway reconstruction project hit a snag this week.

The outside edge of some of the recently poured concrete, a strip of 12-inches, had to be removed and replaced because of a problem with the placement of tie-bars.

Alexandria Mayor Sara Carlson and City Engineer Tim Schoonhoven stopped at the newspaper Thursday to explain the situation.

“There is nothing wrong with the concrete itself,” Schoonhoven said. “Tie-bars are steel bars that serve to connect the concrete slabs between lanes. It was discovered Tuesday that some of the tie-bars were not sufficiently adhered to the concrete.”

The Minnesota Department of Transportation immediately mobilized its engineers and concrete specialists to evaluate the problem, he added.

“Ultimately, it was determined that the solution was to remove the tie-bars in question, along with a strip of concrete along the outside portion of the lanes,” Schoonhoven said. “New tie-bars will be drilled into the concrete slab and incorporated into the remaining pavement.”

Carlson noted that this work began Thursday morning and is proceeding at full speed.

The problem will set the project back a few days, the mayor added, but crews are trying to make up the time. A revised schedule will be completed Monday.

Any extra expense from the problem will be worked out between MnDOT and the contractor.
