Imagine an asphalt ribbon of state Route 410 slicing through Enumclaw with traffic-slowing roundabouts at each end of town and a landscaped median separating two lanes of traffic.

Such a development might seem like a dream to some and a nightmare to others, but it’s all part of a 410 corridor study that is heading toward final development.

As part of the planning process, the public is invited to a Thursday session at the Enumclaw library, 1700 First St. Between 6 and 8 p.m., citizens can view draft recommendations, ask questions and make comments about the proposed corridor plan.

Rand Black, an engineer with the city’s Department of Public Works, said the 410 corridor study looks at the state highway from the intersection with 244th south of the city and an area east of Farman Road. Getting most of the attention is the middle segment, stretching from the Cole Street intersection to a spot east of Watson Road, which is expected to become a busy place as housing continues to grow in the city’s east end.

The 410 study is being done by Transpo Group, a Seattle-area consulting firm. Approximately half the cost was paid by a $60,000 federal grant, Black said, and the city picked up the tab for the rest.

Black said the study remains in its formative stage, not yet ready to receive “draft” status. Before than occurs, the city hopes to gauge public opinion.

“We want public comment before we move forward,” he said, noting that city staff will be on hand Thursday, along with Transpo Group representatives.

The 410 study examines items like intersection improvements, channelization and current and future traffic volume. The most ambitious recommendation, Black said, is the development of two roundabouts that would serve as “landscaped portal entries” to the heart of the 410 business district.

Another key part of the highway study, he said, involves the angled intersection of 410 and Griffin Avenue, which also serves as state Route 164.

“It really doesn’t meet state standards right now,” Black said.
