These quick, convenient, and high-quality tunnel washes were conceived by Olson Oil, and the first one went up as a stand-alone car wash in Brookings, SD.  A second quickly followed on 41^st street in Sioux Falls.  Future sites are in development with some under construction.  The next Blue Tide Car Wash to be completed will share a site with one of Olson Oil’s Get-n-Go convenient stores, in southeast Sioux Falls.  RSA provided the architectural services, collaborating heavily with the manufacturers of the wash system.
