Welcome to the I-90 Exit 59 (N. LaCrosse Street) Interchange Improvements Project virtual Construction Information Meeting
Due to limitations on public gatherings recommended by the Centers for Disease Control, the SDDOT is hosting this meeting virtually, in lieu of presenting information at an in person construction information meeting.
The South Dakota Department of Transportation (SDDOT) in coordination with the City of Rapid City are constructing improvements at the I-90 Exit 59 (N. LaCrosse Street) Interchange and on I-90 between Exit 58 (N. Haines Avenue) and Exit 59 (N. LaCrosse Street). This virtual construction information meeting is intended to provide information regarding the project, including information on construction sequencing and initial planned street/lane closures and detours for the first phases of construction. The project has been planned, designed, a contractor has been awarded the construction contract, and now it is time for construction to begin!
