Final Environmental Assessment for Gate 5 (Central Avenue) Interchange Improvements on F. E. Warren Air Force Base, Wyoming.

摘要

1. INTRODUCTION. F. E. Warren Air Force Base (FEW) or Installation is proposing to realign traffic lanes at Gate 5 (Central Avenue) and add a visitor's parking lot. 2. PURPOSE AND NEED FOR ACTION. The purpose of this action is to provide safe access to FEW for government, personal and commercial vehicles. FEW intends to close Gate 2 to commercial vehicle traffic, due to the unsafe conditions on the Missile Drive Bridge beyond Gate 2. The Missile Drive Bridge beyond Gate 2 is not deemed safe enough to handle the daily continuous passage of commercial vehicles. It is slated for future repair and replacement. Gate 2 currently processes the majority of the commercial traffic coming onto the Installation. Commercial traffic will be re-directed to Gate 5; Gate 5 has a commercial vehicle inspection bay, and thus has a greater capability to handle the intake of commercial traffic than either Gate 1 or Gate 3. Although Gate 5 has a large commercial inspection bay, the roads leading to Gate 5 were not designed to handle the increased commercial traffic is re-routed . Since Gate 5 is currently unable to handle the anticipated higher volume of commercial vehicular traffic, Gate 5 will require additional vehicle lanes and realignment of the Central Avenue entrance. Additionally, Gate 5 will have to handle all commercial traffic while the Missile Drive Bridge replacement at Gate 2 is being constructed. Thus, the proposed action will allow safe and expedient access to FEW for all vehicle traffic. 3. SCOPE OF THE ENVIRONMENTAL ASSESSMENT. This Environmental Assessment (EA) is required by the Air Force Environmental Impact Analysis Process (32 CFR 989) and the National Environmental Policy Act (Public Law 91-190), Council on Environmental Quality (CEQ) Regulations (40 CFR Parts 1500- 1508). This EA identifies, describes, and evaluates the potential direct, indirect, and cumulative environmental impacts that could result from the construction of the proposed action.
