Station locations are designated with a yellow triangle. 6 Stations Total Slide #18 Elevated Loop Stations Challenges/Issues * Age and condition of existing structure * Space and height restrictions, highly congested area with streets below and building constraints * Potential use of combination of elevators and ramps (similar to Clinton station on Green/Pink Line) 1 photo shows an elevated station with the street below and the other photo shows the ramps of Clinton station Slide #19 Historic Stations * Station house layout: Station house located at street level accessed from street level * Platform configuration: Side-loaded type platform above street level Three photos show historic stations’ entrances and elevated platform. Slide #20 Historic Stations A system map showslocations of the following stations Custom Design Required: (Blue Line) California, Damen. Station locations are designated with a yellow triangle. 2 Stations Total Slide #21 Historic Stations Challenges/Issues * Structural issues due to age of station buildings * Located in congested areas (businesses on both sides) – may require land acquisition for elevator * Historic preservation of existing building poses constraints on elevator configuration * Side loaded type platforms will require two elevators * Ramps not desirable due to site constraints 2 photos show the historic station entrances and adjacent business signs.
