I-205 Access and Operations Study
In November 2014, the RTC Board adopted recommendations to address long and short term roadway improvements and transit operations in the I-205 corridor as well a set of operational policies for regional freeway corridors in the region. These recommendations identified a core set of long term I-205 capital projects for the RTP and a set of near term I-205 operational projects to improve performance and efficiency of the I-205 corridor. These include projects such as ramp metering and improving lane utilization to manage congestion and make better use of existing capacity.
The transit recommendations call for pursuing an I-205 Bus on Shoulder Feasibility Study of the technical, policy engineering opportunities and constraints of bus on shoulder operations in the I-205 corridor. The operational policies adopted by the Board provide guidance for the consideration and evaluation of operational strategies in freeway corridors and guides the implementation of ramp meters.
- Roadway Improvements
- Add 2035 Core Projects into the 2014 RTP as capacity improvements for I-205
- WSDOT lead to implement short term operational improvements
- Transit Operations
- Bus on Shoulder assessment found time savings, reliability, and improved commuter ridership potential
- Recommend feasibility study in 2015 to address viability, engineering, costs, and constraints
- Operational Policies
- Policies for regional freeways
- Analysis factors for considering strategies
- Implementation policies for ramp metering
