Abstract

In response to a court action, a plan was developed to mitigate potentially hazardous effects of fog on a proposed highway bridge. The proposed site is subject to naturally occurring fog in addition to fog consisting of large quantities of water vapor emitted by a paper mill. A study was conducted to evaluate available mitigation measures. The measures evaluated include dispersion systems, guidance systems, design alternatives, transportation management, and incident detection. The purpose of this paper is to present the conclusions of the study. On the basis of the study results, a fog mitigation plan was recommended. The plan consists primarily of guidance and surveillance measures. The major components of the recommended plan include fixed message signs, raised reflective pavement markers, lighted pavement markers, highway surveillance, and variable message signs. The recommended plan was accepted by the governing agency and will be implemented. In addition, other considerations, which are presented in this paper, will be explored while the proposed bridge is under construction.
