I-205 - Mill Plain Exit - 112th Connector - Complete February 2010

Overview
This project provided a direct connection to NE 112th Avenue from the northbound I-205 off-ramp to westbound Mill Plain Boulevard. This was a partnership project with the City of Vancouver.

The close proximity of previous traffic signals and the high traffic volumes on Mill Plain Boulevard often resulted in long delays and traffic back-ups at the intersection of Mill Plain Boulevard and Chkalov Drive.

This congestion, combined with high volumes of traffic exiting northbound I-205 onto Mill Plain during peak travel times, resulted in congested freeway off ramps. Cars were lined up in the exit lane, impeding the traffic flow on northbound I-205 and westbound State Route 14. This congestion posed a significant safety concern and contributed to substantial delays and motorist frustration. A significant portion of the exiting traffic in this area was bound for NE 112th Avenue.

This effort is part of strategic improvements to the I-205 freeway ramp network that has been in the planning stages for many years.
