A construction project on U.S. Highway 20 in Waterloo will impact the flow of traffic for the next seven months.

Work to rebuild a portion of the eastbound lanes is scheduled to begin Thursday, weather permitting. According to the Iowa Department of Transportation (IDOT), crews will be removing and replacing pavement along a three-mile stretch of the highway's eastbound lanes between U.S. Highway 63 (Sergeant Road) and Iowa Highway 21 (Hawkeye Road).

IDOT officials said the project will result in head-to-head traffic on U.S. 20, using the westbound lanes. Three ramps for eastbound U.S. 20 traffic will be closed during the project:

  • U.S. 63 exit and entrance ramps
  • Ansborough Ave. exit and entrance ramps
  • Iowa 21 exit and entrance ramps

According to IDOT officials, marked detours will be in place to assist traffic through the area.

IDOT officials said constructon on the eastbound lanes of U.S. 20 is expected to be completed by early July, then work to rebuild the westbound lanes will begin. Weather permitting, the entire project is scheduled to be finished by mid-November.

Another construction project is set to begin in Chickasaw County on April 24, which will force the closure of Iowa Highway 24 between New Hampton and Lawler for about one month.

According to IDOT officials, workers are scheduled to remove and replace a pipe culvert two miles west of Lawler. During the project, a marked detour will direct motorists around the construction zone using U.S. Highways 63/18 and Chickasaw County roads B-54 and V-48.

The Iowa 24 project is expected to be completed by mid-May, weather permitting, IDOT officials said.

LOOK: Stunning vintage photos capture the beauty of America's national parks

Today these parks are located throughout the country in 25 states and the U.S. Virgin Islands. The land encompassing them was either purchased or donated, though much of it had been inhabited by native people for thousands of years before the founding of the United States. These areas are protected and revered as educational resources about the natural world, and as spaces for exploration.
