RAPID CITY, S.D. – The South Dakota Department of Transportation says construction will start for High Friction Surface Treatment (HFST) on eastbound Interstate 90, near Exit 55 (Deadwood Ave), on Thursday, Aug.15.


A lane closure will be set up on I-90 through the construction zone during daytime hours.  The Deadwood Avenue to eastbound I-90 on ramp will remain open during construction.


The project involves grinding the concrete surface, sealing the joints between concrete slabs and then applying the HFST.


The High Friction Surface Treatment is used on specific stretches of highways to improve safety by applying a skid resistant surface. According to the Federal Highway Administration, HFST’s are proven to dramatically and immediately reduce crashes, injuries, and fatalities associated with friction issues.


Louis-Company, Inc., of Lees Summit, Missouri is the prime contractor on this $940,000 project.


This project has an overall completion date of Sept. 27, 2019
