NOTES

BUDGET/SCHEDULE

EXPERIENCE

• Provide connections between the light rail station and destinations on Marquam Hill

• Provide an efficient, convenient, equitable and comfortable connection for all types of users

• Create a safe and secure connection for all users

• Best fit with, enhance, and improve the unique historic, scenic, recreational and design character of this area

• Protect or enhance the area’s natural resources and sensitive habitat

• Provide a long-term, sustainable connection for current and future users

• Be cost effective and timely within the Southwest Corridor Light Rail Project

• Create a signature connection that provides a high-quality user experience and inspires civic pride

• Weather protection is inherent • Indirect access to OHSU lower campus, VA

Hospital, & recreational destinations• Long walk underground (675 ft/3.5 city blocks),

moving walkway may be incorporated

• Minimizes visual impacts on surroundings• Maintains use & identity of Terwilliger Parkway

• Construction footprint limited to portal & shaft construction areas

• Construction activities require monitoring for noise & vibration impacts to surroundings, debris hauling will impact adjacent roadways

• No precedent for a pedestrian tunnel of this scale in Portland, operational issues require further study

• Complex to maintain, may include attendants, limited hours, and/or user fee

• Approximate cost: $55-125 million• Difficult construction type, very high risk of cost

& schedule overruns

• Challenging environment to make high quality pedestrian experience

• Minimizes conflicts among modes• Users have low visibility from surrounding area• Will require monitoring equipment and/or staff

for security
