Timber Bridges have become a viable alternative for new bridge construction on low-volume roads, where it is imperative that the bridges be economical and long-lasting. The objectives of this booklet are: (1) to present background information on timber substructures, (2) to present practical design guidelines for various systems, and (3) to present sources of additional information. The following six systems were selected: timber piles, steel bent-pile abutments, culverts, crib-wall abutments, and stub abutments. |
