				Project Overview
				Concurrently with the Upper Demunds Intersection Project, improvements will be completed at the Tunkhannock Highway (SR 0309) and Memorial Highway (SR 0415) intersection in Dallas Borough, Luzerne County, Pennsylvania. This project involves the provision of additional left-turn capacity on the Tunkhannock Highway (SR 0309) approach in order to improve the current conditions, as well as to better accommodate future traffic growth. Additionally, this improvement will help to maintain traffic operations during the detours as a result of the construction of the Dallas Five-Leg Intersection Improvement (documented by PennDOT as SR 0415, Section 303).

				Traffic Volumes & Levels of Service
				Traffic operational analysis was completed for the intersection of Memorial Highway (PA Route 415) and Tunkhannock Highway (PA Route 309) during the weekday morning commuter, weekday afternoon commuter, and Saturday midday peak hours for Existing Conditions, 2014 Future No-Build Conditions, and 2014 Future Build Conditions. Figures illustrating the intersection traffic volumes and levels of service are provided below.
				Existing Conditions
				Overall, the intersection operates with delay during the weekday morning computer peak hour and the Saturday midday peak hour. The southbound PA Route 309 left-turn/through movement operates with delay (LOS E and F) during all three study peak hours.
				2014 Future No-Build Conditions
				Overall, the intersection will continue to operate with delay (LOS F) during the weekday morning computer peak hour and Saturday midday peak hour, and with delay (LOS F) on the southbound PA Route 309 left-turn/through movement during all three study peak hours.
				2014 Future Build Conditions
				With the additional left-turn capacity on the Tunkhannock Highway (S.R. 0 309) approach, the intersection will operate at acceptable LOS C or better conditions overall during all three peak hours. Additionally, all movements at the intersection will operate at acceptable LOS D or better during all three peak hours.
