The 2017 in-depth web training features the Utah DOT’s Accelerated Bridge Program. The Utah DOT’s Structures Division has championed and widely implemented ABC, and the use of ABC is now common practice throughout the State of Utah. Previous ABC design documents and supporting drawings have been incorporated into the Structures Design and Detailing Manual which consists of the manual, drawings, and checklists. Designers, fabricators, and contractors are on board with the use of ABC. Inspections show good long-term performance of ABC bridges. The six modules of the 2017 in-depth web training provide a comprehensive description of Utah’s ABC implementation.
