Should we address the traffic issues at the I-5 Interchanges in Downtown Vancouver?

Description
Modify ramps between SR 500 and Interstate Bridge (both north and south bound) to reduce conflicts caused by high traffic volumes in weaving and merging sections.
Transportation Performance
  • These ramp improvements would eliminate four problem merging, weaving, and diverging freeway segments between SR 500, E. 39th Street, 4th Plain, and Mill Plain interchanges. This reduces high-speed conflict points and improves traffic safety.
  • Improves access to downtown Vancouver by reducing ramp-related congestion and delay.
  • Supports provision of new southbound off-ramp to E. 6th Street in downtown Vancouver.
Displacements
Current conceptual designs displace as many as 32 residential properties and 3 non-residential properties.
Cost
Construction Cost (2001 $): $93 million
