A public open house was held discussing the I-90 Exit 61-67 corridor study

Posted: Updated:

The South Dakota Department of Transportation (SDDOT), in collaboration with the Rapid City Metropolitan Planning Organization (MPO) and the city of Box Elder held a public open house on March 6.

The meeting was held to inform area residents on options developed as part of a corridor study for Interstate-90 from Exit 61 (Elk Vale Road) to Exit 67 (Liberty Boulevard/EAFB Main Gate).

“Our pavement management system, has triggered that section of I-90, of needing pavement replacement in the next 5-6 years, and before we go in and put 40-year new pavement down, we want to make sure all the ramps are where they need to be,” said planning engineer, Steven Gramm.

Two primary areas that are being studied include the capacity of the I-90 corridor as well as interchange access.

A total of 11 alternatives had been created, with 6 of those options moving forward in the planning process.

The alternatives that will move forward include:

  • Interchange at Westgate Road
  • Interchange at Westgate Road with direct access to EB 1416
  • Interchange at Westgate Road with existing west ramps and new east ramps
  • Interchange at Highway 1416
  • Remove Exit 63
  • No action

A tentative date is set for early summer in the final decision for the outcome of the corridor.

For those who did not attend the meeting or would like additional information on the study, information will be made available online at www.i90corridor61to67.com.
