1990: Bridge inspections and more counties
In 1990, we became Swift & Guy Engineers, Inc. City of Tulsa street maintenance projects, county bridge design for Mayes and Nowata counties, and off-system bridge inspection for Nowata, Osage and Craig counties were our work staples. ODOT Local Government liked the detailed plans we prepared as we learned the “ODOT way” of plan preparation.
