TERRE HAUTE, Ind. (WTWO/WAWV)– The Vigo County Commissioners approved a change order on Tuesday to extend construction on the 13th street bridge over Lost Creek until the end of the year.

The changes, which were requested by Vigo County engineer Larry Robbins, will cost just over additional $225,000 on top of the $1.5 million for the original repairs. Robbin said the changes were needed because the abutments for the bridge were found to be insufficient.

“The abutments were anticipated to be 30 inches thick, they were actually only 12 inches thick, which poses a problem for the loading of the bridge and the lifespan of the bridge,” Robbins said.

Robbins said this is considered the cheapest alternative to thicken the abutments and repair the bridge.

“It’s a lot of concrete work and a lot of form work, which is fairly expensive at this time. You’ve seen increases in inflation and costs for labor, they’re kind of unprecedented this year,” he said.

President of the Vigo County commissioners, Chris Switzer, said the additional time and cost for the project could affect repair work on other bridges in the county.

“That kind of impact projects moving forward, having an extra $200,000 extra expense to one specific bridge, so I think we’re going to have to re-evaluate some things moving forward the rest of this year and into next year on some other bridges that we’ll have to do,” Switzer said.

The original plan projected for the construction to finish in September, but now that’s pushed back to at least the end of 2022.
