Bridge Standard Details (XS) are developed and maintained by the Division of Engineering Services (DES) Technical Organization. The sheets contain pre-engineered details for a variety of structural systems, such as earth retaining systems, bridge railings and underground structures. Bridge standard details are not Standard Plans and are subject to frequent modification.
The details are considered to be “Project Plans” for contract administration purposes in accordance with Section 5-1.02 “Contract Components”, of the Standard Specifications.
