Frequently Asked Questions
When will construction begin and how long will it last?
Construction on Memorial Highway began around April 1st, 2025, and last until mid-November. Reconstruction of the entire stretch of roadway between Main St. and 46th Ave. will likely be spread over two or three consecutive construction seasons. The entire corridor will not be under construction at one time.
How will businesses, landowners, and the public stay informed throughout the project?
We will utilize several methods of communication. The project website, email, and newsletter will be the primary forms of communication with business owners along the corridor. The project website will house updates throughout the duration. You will also be able to ask questions by filling out the following form: Memorial Highway Project Contact Form
How will access be maintained to businesses during construction?
Temporary access will be maintained during construction; however, there is potential for short closures during construction activities such as underground utility installation and roadway paving.
Two hard-surfaced travel lanes and a hard-surfaced center turn lane will always be provided; some temporary aggregate accesses may need to be utilized. If your existing access cannot be maintained, other access will be provided to ensure traffic will be able to get to your business. If there are concerns with construction, please contact Reede Construction at 605-225-7082.
Will Memorial Highway be closed to traffic during construction?
One lane of traffic in each direction with a center turn lane will be maintained throughout the duration of construction. Traffic control will be maintained in sections and the contractor will need to modify and adjust traffic control to maintain a safe working environment. Please stay alert to changes in traffic flow, as they may occur quickly as construction progresses.
How is the roadway drainage being improved?
The roadway is being reconstructed as an urban section including curb and gutter and an underground storm sewer system. Additional drainage improvements may include a shallow ditch in some areas to collect off-site storm water and reduce ponding on adjacent properties where possible.
