Thank you for submitting the request through the UDOT website however we are unable to be of assistance. UDOT only maintains state and federal routes like S.R. 68 (Redwood Rd.) and U.S. 89 (State St.). 11400 S 1815 E at this location is maintained by Sandy City. I have forwarded the information on to them. If you have additional questions or would like to follow up I would recommend contacting them directly, https://sandy.utah.gov/departments/public-utilities
