The Pontis Bridge Inspection Coding Guide was developed by the Staff Bridge Branch of the Colorado Department of Transportation. This revision includes cross references to the General Comments and Definitions necessary to provide for uniform inspection reports from various bridge inspectors and is intended to supplement the AASHTO Guide for Commonly Recognized (CoRe) Structural Elements with clarifying information and additional elements unique to...

In September, 2013, a slow-moving cold front stalled over Colorado, clashing with warm humid air from the south, resulting in a severe rain event that lasted a week and caused catastrophic flooding and damage along Colorados Front Range. Flood impacts were widespread, particularly across northern Colorado, where rockslides, landslides, mudslides and washouts caused major damage and, in some cases, total destruction of residences, roadways and local...

The people of Puddletrunk are accustomed to their bridge collapsing and being rebuilt by Mortimer Gulch--when they provide funds and labor--but a newcomer to town may have a better idea.

Self-consolidating concrete (SCC) is a stable and highly flowable concrete that consolidates without the help of external vibration and can flow through heavy reinforcement and around corners in complex formwork under its own weight. The exceptional performance of this remarkable material has attracted the attention of construction firms and DOTs in the United States interested in using SCC on new bridge construction and bridge repair projects.

The study found that FAST systems have demonstrated the potential to reduce the number of crashes and reduce the cost of winter maintenance activities, if sited at appropriate locations (e.g., high-traffic-volume ice-prone ramps). However, improved installation techniques and involvement of maintenance crews during FAST installation are necessary to further increase the cost-effectiveness of a FAST system deployment. Extra effort will be made in sharing...
