SW Vermont from 45th to 52nd: Alternative 1

Alternative 1 – In Street Southside Multiuse Path: In an effort to minimize costs, the first alternative to be considered is situated on the roadway surface. With the existing continuous sidewalk facility west of this segment is on the south side of SW Vermont St, the logical decision is to keep the pedestrian facility on the south side of the roadway to minimize pedestrian crossings. In this alternative, the multiuse path extended westward from the end of the existing sidewalk to link to the existing neighborhood greenway at SW 52nd Ave. Bike lanes connect the bike gap between SW Idaho Dr and SW 45th Ave. Westbound cyclists from the bike lane are routed to the frontage road to reach SW 50th Ave. The available pavement width in this situation is 36 feet. Given the presence of Trimet buses along this corridor, the recommended minimum travel lane width is 21 feet for two-way traffic. Ten feet is allocated to the eastbound direction since this travel lane is adjacent to a buffer zone. The westbound lane is allocated eleven feet since it is adjacent to the edge of pavement. A one-foot shoulder delineates the edge of pavement. A minimum three-foot buffer separates the eastbound travel lane from the multiuse path which takes the remaining eleven feet.

Advantages: Least expensive option, Consolidates neighborhood greenway crossing at one intersection

Disadvantages: Lowest level of separation between pedestrians and traffic, Largest distance of shared space between bikes and pedestrians, No shoulder space available for pedestrians on the north side of the street.
