Heart River Bridge Construction to Begin

The North Dakota Department of Transportation (NDDOT) is planning to begin repair work on the Heart River Bridge, also known as Sitting Bull Bridge, on Highway 1806 S on Monday, April 25. Bridge work is expected to take about four months to complete with both lanes of traffic remaining open during construction.

Minor bridge repairs are part of a larger Highway 1806 S construction project planned for summer. Highway 1806 S from Main Street to Eighth Ave SE will undergo traffic signal replacement, concrete pavement repair, and lane reallocation with striping changes. A portion of the roadway that is four lanes will be reconfigured to three lanes with a dedicated left turn lane. Other improvements include curb ramp and lighting updates.

The City’s cost share of the $2.27 million project is 10% to be covered through the sales tax fund.

Please contact NDDOT Project Engineer Loren Lee at 701-328-6961 with construction questions. Updates will be posted periodically at cityofmandan.com/roadprojects.
