Transportation research record, 2001•journals.sagepub.comThe Upper Narrows Tunnel on Highway 160 in southern Colorado has been designed with
a unique system of escape adits to provide for life safety in the event of emergencies in the
tunnel. The use of adits provides for a higher level of safety in this application than would be
provided by the more common ventilation system. A summary of the unique project
conditions that facilitate such a system is presented, and the methods of analyses and
results of calculations used during the design are reviewed.
