摘要：	The safety improvement project for a section of US 119 across Pine Mountain in Letcher County was initiated as an interim effort to address safety issues related to roadway geometrics and specific problems related to truck traffic. The project involves sections of the road being improved over a 7.2-mile length at a cost of approximately $36 million. The Transportation Center at the University of Kentucky was requested to perform an evaluation of the safety improvement project on US 119 to determine whether the types of improvements undertaken have affected the overall safety ban of the roadway. Specific objectives were as follows: (1) to determine the effects of a ban on truck traffic that was implemented in March 2001, (2) to determine if the types of improvements undertaken as part of the project are applicable to other locations, and (3) to determine if the use of flexible design was successful by allowing the Transportation Cabinet to remove the truck restriction by permitting trucks with dimensions up to the WB-50 design to travel across the mountain and be able to track within their own lane. This interim report documents crash data prior to and after implementation of the truck ban and during construction.
