T.F. <strong>Green</strong> <strong>Airport</strong> <strong>Improvement</strong> <strong>Program</strong>Environmental Impact Statement and Final Section 4(f) EvaluationWhile plans are at the conceptual level, in order to accommodate Realigned Main Avenue, portions of thefollowing public streets are likely to have modified access and circulation:• Main Avenue at Route 113 (alignment shift only)• Gertrude Avenue• Bedford Avenue• Taft Avenue• Groveland Avenue• Walnut Glen Drive• Gladys CourtAll roadways that currently have access to Main Avenue would still have access after the roadway is realigned.There are no proposed changes to traffic control (stop signs or traffic signals) at any location along MainAvenue, although some traffic signals may be modified to be more efficient if necessary. When consideringroadways that may be modified, final roadway alignments, road closures, discontinuances, and newconnections would be determined by RIAC and RIDOT, and notification to the public and affected partieswould follow RIDOT protocol.Traffic Impacts – 2020/2025Additional passenger demand would be generated under Alternative B4 in 2020 because of additionalenplanements due to forecasted changes in <strong>Airport</strong> activity (enplanements, deplanements, and employment)and not due to any infrastructure improvements or projects. The number of enplanements in 2020 and 2025 isthe same under Alternatives B2 and B4. Realigned Main Avenue and Partially Relocated <strong>Airport</strong> Road would beconstructed by 2015 (described previously) and would remain in the same location with no additional physicalimprovement in 2020 and 2025.Additional changes that would take place by 2020 include an improved Terminal Area Roadway, which wouldconsist of a new Post Road “Gateway Entrance” to the <strong>Airport</strong>, South Access Road, a South Circulation Road, aService Area Road, and alterations to the Lower and Upper Level Terminal Roadways. The existing <strong>Airport</strong>access to Post Road south of the <strong>Airport</strong> Connector would be closed. These on-<strong>Airport</strong> roadway improvementsare identical to those proposed for Alternative B2.Effects on Daily Traffic – 2020/2025Under Alternative B4 in 2020 and 2025, new traffic in the Study Area would be <strong>Airport</strong>-generated trafficresulting from the extension of Runway 5-23. Alternative B4 would result in increased traffic on all roadwaysegments studied when compared to the No-Action Alternative. The increases range from 8.1 percent to10.8 percent in 2020 and from 7.5 percent to 10.8 percent in 2025.Effects on VMT and VHT – 2020/2025Alternative B4 would result in minor decreases in VMT and VHT in both 2020 and 2025 compared to theNo-Action Alternative. Under Alternative B4, VMT would decrease by 0.5 percent in both 2020 and 2025. VHTwould decrease by 0.4 percent in 2020 and by 0.8 percent in 2025.Chapter 5 - Environmental Consequences 5-137 July 2011\\mawatr\ev\09228.00\reports\<strong>FEIS</strong>_Final_July_2011\<strong>PVD</strong>_CH05_Environmental_Cons_JUL_2011.doc
