  1. WEST THOMAS STREET PEDESTRIAN AND BICYCLE OVERPASS Seattle Design Commission Update – October 15, 2009

  2. WEST THOMAS STREET PEDESTRIAN AND BICYCLE OVERPASS Summary of Seattle Design Commission • December 2004 • Suggestion to span over Elliott Ave and/or improve Elliott Ave crossing • Design bridge to be “simple”, “minimal”, and “harmonious and complimentary” • July 2006 • Support the extended scope to include extending overpass across Elliott • Support “simplicity of ramps and pursuit of design elegance” • Design treatments, especially throw fence • December 2006 • Addition of stairways • Consider ramp to touch down on W. Harrison St. • Curved alignment for the bridge • January 2008 • Re-evaluate design to consider natural setting • Concerns related to the Elliott crossing, pedestrian improvements versus overpass • Phasing of the project due to funding • February 2008 • Inclusion of stairs at Elliott Ave. • Inclusion of belvedere at Park and West Thomas triangle • Functional but considers safety of users. • Use of “green” technology and compliment Park setting

  4. WEST THOMAS STREET PEDESTRIAN AND BICYCLE OVERPASS Project Status • Evaluate Project Funding • Conducted Value Engineering study to re-evaluate design • Re-evaluate current scope • Shorten structure • ADA compliance • Future expansion • Pedestrian improvements at Elliott Ave • Streamlining architectural enhancements • Minimize special fabrication • Use of standard steel sections • Consider future maintenance costs • Consider color scheme • Phased construction • Construction of intermediate access points • Build structure over railroad, future expansion over Elliott Ave • Consider future maintenance costs • Consider color scheme

  5. WEST THOMAS STREET PEDESTRIAN AND BICYCLE OVERPASS Design Moving Forward • Maintain alignment • Maintained a “simple” and “minimal” design using smooth tube sections • Use of surface mounted pedestrian luminaries and consider accent lighting fixtures ~10’ • Maintain belvederes and design structure for future intermediate access • Incorporate art enhancements based upon Potlatch Trail art concepts (SDC 2002) • Complete design expeditiously and as efficiently as possible • Continue seeking alternative funding sources • Goal to provide access and preserve natural setting
