Update on RTD’s SBE Certification Program

Please be advised: As of Monday, February 22, 2021, RTD temporarily suspended its Small Business Certification (SBE) and will not be accepting or processing new SBE certifications until further notice. If you are currently certified with RTD as an SBE, RTD will continue to process the annual updates and renewals of your RTD SBE certifications. RTD will continue to set SBE goals on our locally funded projects and honor RTD SBE certifications on RTD contracts with SBE goals.
