FOSTER ROAD CROSS SECTIONDRAFT ALTERNATIVESThe graphics illustrated below display different cross sectional alternatives for the three
representative segments of inner Foster Road. These segments include SE 52nd Avenue to SE 72ndAvenue, SE 72nd Avenue to SE 80th Avenue, and SE 84th Avenue to the Couplet. Each cross
section alternative is a typical block for its respective segment and is supported with a table that
conveys at a broad level modal tradeoffs as design features within the cross section that are either
introduced, removed, moved, expanded, or reduced. Each segment includes at least one cross
section option incorporating key values identified by the community and staff, including:
A 4-lane option A 3-lane option A 2-lane option Conventional bike lanes in both directions Separated bike facilities in both directions
