Posted on: July 21, 2016

MANCHESTER, Iowa – July 21, 2016 – Construction on U.S. 20 at the Dyersville Industrial Park interchange moves to the second stage and traffic will be shifted to the newly constructed eastbound lanes of U.S. 20 during the week of July 25, weather permitting, according to the Iowa Department of Transportation’s Manchester construction office.

U.S. 20 traffic impacts

  • U.S. 20 traffic will be switched to the eastbound lanes where traffic will be maintained in each direction. It will take approximately one week to complete the traffic switch.
  • The width restriction for eastbound U.S. 20 will be removed; approximately 20-foot wide loads will be accommodated in each direction.
  • The eastbound U.S. 20 exit ramp will be opened for southbound traffic.
  • Industrial park traffic for westbound traffic will continue to use the frontage road to the Seventh Street intersection for access to U.S. 20.
  • Traffic should be returned to normal traffic patterns by early November. This includes the opening of the ramps on the interchange and closing Seventh Avenue and 320th Avenue.

Steger Construction of Dyersville is the main contractor for this $10 million construction project.
