BETTENDORF, Iowa (AP) - Officials for the Iowa Department of Transportation say unexpected bedrock in downtown Bettendorf is slowing down work to realign streets for the construction of a new bridge over the Mississippi River.

Department construction engineer Mark Brandl says the bedrock is some of the hardest that their contractors have ever encountered, and the primary issue is the amount of bedrock crews have to deal with. Project manager Boone Zimmerman said his crews have encountered more bedrock than they expected during the realignment and reconstruction for the new Interstate 74 bridge.

Zimmerman says chipping through the bedrock slows down their work because it takes so long to remove it. He said crews also have to relocate sewer and water lines.

According to Zimmerman, removing the rock has slowed work down, but he hopes to have three open lanes of traffic by Nov. 30.

Brandl does say things are looking a better despite the number of issues that have run into.

“We’re certainly hoping Mother Nature gives us a break here in November so we can get that done,” Brandl said.

The Quad-City Times (http://bit.ly/1L6tDTW reports Langman Construction Inc. of Rock Island is overseeing the realignment and reconstruction of the streets ahead for the $18.8 million project ahead of the bridge construction.

The newspaper reports the Iowa Department of Transportation will have acquired and knocked down 44 properties by the end of the year as part of the project.

The transportation department hopes to tear down the current bridge in 2021.
