Project Information

The Garden Corner Curves Corridor is a narrow, constrained roadway which accommodates people driving, walking and biking. The corridor includes SW 105th Avenue, SW Blake Street, and SW 108th Avenue - a map of the corridor is shown HERE. The goal of this project is to develop solutions that balance cost, safety for all users, community needs, environmental impacts, and right-of-way.

          Key Issues

  • Narrow  roadway with limited public right-of-way available to widen or construct other improvements
  • Road is used by people walking and biking, with no separated path, and little to no shoulder
  • Road has sharp curves, limited visibility, there are steep banks/ditches beyond the edge of pavement

Phase 1

Phase 1 (through end of 2020) work this year will include improvements that slow traffic like narrowing the roadway and building the raised crosswalk at 108th Ave and Blake St.

Phase 2

Phase 2 (through fall 2021) work next year will include replacing the creek culvert and sewer line, construction of the trail, stormwater planter, and reconstruction of the roadway.
