The state Highway 14 corridor in Vancouver is notorious for rush hour congestion, with an especially unpleasant chokepoint between Interstate 205 and Southeast 164th Avenue that tends to tie up commuters heading for Oregon.
The Washington State Department of Transportation has a project in the works aimed at easing that bottleneck, and construction is scheduled to kick off early next year.
“When we did initial modeling, (we found that) you can count on this corridor being congested every single day,” WSDOT traffic operations planning engineer Michael Southwick said. The congestion follows a rush hour pattern, he said, although the morning westbound congestion tends to be worse than its eastbound evening counterpart.
That’s based on data from before the COVID-19 pandemic, he added. Traffic volumes dropped last year but have been steadily climbing back.
The $25.4 million project aims to address the congestion by adding a third main travel lane in each direction on state Highway 14 between I-205 and 164th Avenue, along with ramp meters at 164th Avenue and a westbound “peak-use shoulder lane” to address the especially nasty westbound jam-ups.
