Synthesis of Highway Practice 327
Cost Effective Structures for Off-system Bridges

TRB’s National Cooperative Highway Research Program (NCHRP) Synthesis 327: Cost-Effective Practices for Off-System and Local Interest Bridges examines off-system bridge design, construction, maintenance, financing, rehabilitation, and replacement. For this report, 'off-system' refers to those bridges typically owned and maintained by local agencies, and by state agencies on rural and other low-volume roads.  This topic is published at https://www.trb.org/news/blurb_detail.asp?id=4344
