*Consult the roadway freight map for additional design considerations.
**While these facilities do not include bike lanes, they do include wide travel lanes of 14 feet due to constrained right-of-way width –
see Footnotes 2 and 5.
Footnotes:
1. The maximum number of travel lanes that can be built without a plan amendment is identified on the “Road Lane Numbers” Map
except for roads allowed to be built as provided by the Community Development Code (CDC). This plan-level decision establishes the
transportation system capacity necessary to adequately serve future travel demand identified in the TSP. The number of lanes required
to accommodate turning movements at intersections and interchanges will be determined through traffic analysis conducted during the
transportation project development process. This project-level decision identifies physical improvements necessary at or near intersections
and interchanges to safely and efficiently move toward attaining the system capacity identified in the TSP. Improvements may include turn
lanes and auxiliary lanes adjoining the traveled roadway to accommodate weaving, merging, speed changes or other purposes supplemen-
tary to through traffic movement. Auxiliary lanes to address spot area capacity and safety needs may extend between intersections (includ-
ing interchanges) and beyond an intersection. Opportunities for public participation are available as provided by the CDC.
