Eastmont Extension Mainline (Badger Mountain Rd to SR2/28) - Project Summary
Eastmont Extension Mainline
The Eastmont Extension Mainline Project is planned for construction in the 2012/2013 construction seasons and will include construction of a new alignment that will extend Eastmont Avenue from Badger Mountain Road to the intersection of SR 28 and SR 2/97. The roadway will be constructed to Urban Arterial road standards with a 50-foot wide traveled way and curb and gutter on both sides of the roadway. Sidewalk will be constructed along the eastern side of the roadway. The western side of the roadway will have long runs of guardrail and retaining walls with color and finish selected to match the existing wall along Eastmont Avenue to the south. The new road north of the bridge will include a climbing lane for southbound traffic. Intersection along the alignment will be designed with left turn lanes to maintain efficient traffic flow and maximize vehicle capacity. Project Overview (125mb - 36" x 126")
