TRB Webinar: Solutions for Aging Low-Volume Road Bridges

TRB conducted a webinar on Tuesday, October 3, 2017 from 1:00 PM to 2:30 PM ET that illustrates ways to repair old bridges, close bridges, and find alternate structures or routes that adhere to budgetary restraints. Presenters discussed several options, including salvaging old parts, using accelerated bridge construction and modular construction techniques, building geosynthetic reinforced soil bridge abutments, and building long-span buried bridges.

This webinar was organized by the TRB Standing Committee on Low-Volume Roads and the TRB Standing Committee on Culverts and Hydraulic Structures.

The slides and a recording of the webinar are available.
