The Elkhorn Ridge Golf Course in Spearfish will expand to 18 holes. The initial nine holes, clubhouse and practice facility were completed three years ago.
Property owner, Daryll Propp, of Denver, said the completed course will be 7,300 yards long from the back tees.
Current plans are to finalize the design in the upcoming months and obtain bids from qualified golf course contractors this summer. Construction could begin by the end of the year.
