US101/OR6 Traffic Improvement Project



About the Project

ODOT, in cooperation with the City of Tillamook and Tillamook County, is improving traffic performance and safety of US 101 and OR 6 through downtown Tillamook and across Hoquarton Slough. The narrow streets that these highways use were not designed to safely carry the large volume of traffic – particularly truck traffic – moving through Tillamook today.

The project passed a milestone in July of 2012 when the Stakeholder Advisory Committee and Project Management Team unanimously recommended a preferred design which was accepted by ODOT. The project will lengthen the US 101 couplet to the Hoquarton Slough by extending Pacific Avenue north beyond 1st Street and replacing the existing slough bridge with a new four-lane bridge. The new bridge will be up to 5 feet higher than the existing bridge. The project will also widen the travel lanes on Main and Pacific Avenues from 1st to 4th Streets. Turn lanes will be added at key intersections through town.

Construction has now begun. Construction has been funded as part of the State’s Jobs and Transportation Act of 2009. ODOT will continue to involve the public as the project moves forward during the design and construction phases.

Rain, Zippers and Pork Chops- Another Week in the Highway Project

“Weather dependent” was the most used phrase at this week’s Highway Project meeting. Almost all aspects of the project are impacted by rainfall, and crews are constantly trying to predict where to dive in based on the forecast. The work on Main Street in the vaults in front of Everything Pets and Tangled Yarns was delayed slightly while waiting for an inspection, but has now received a green light and excavation and structural reinforcement will get going in the coming days, followed as soon as possible by concrete fill and then curbing and sidewalk building. Electrical work on both temporary and permanent signals on both Pacific and Main will be ongoing in the next couple of weeks, and lane closures may be necessary to accommodate that work.

One of the concerns that has been brought forward is the signage for the merging on southbound 101. Traffic back-ups are challenging and many folks have expressed significant frustration at cars who speed up in the right lane and are “cutting” in the traffic line. When discussing this at the ODOT table, I was directed to an instructional video on “Zipper Merging,” which, while a common practice elsewhere, is foreign to us polite, considerate Mooks. Here is a link to the video:  https://www.youtube.com/watch?v=cX0I8OdK7Tk I recognize that this email and this link are unlikely to change driving patterns that are an inherent part of our culture, but I am hopeful we can together spread the word that “Zipper Merging” is not just jerky people rushing to the front of the line, but rather a taught driving practice. A reminder that we are often all just doing our best that we know how to do.

Construction woes remain similar for next year
October 5, 2017
By Jordan Wolfe, Tillamook Headlight Hearald - September 28, 2017

The past year of construction, according to City Manager Paul Wyntergreen, has been the warm-up for the second half of the Highway 101/6 Project. 

“This is the year when it really hits home – Main Avenue,” he said. “I’d say we’re into this until mid-summer 2018 – and, theoretically, early fall 2018.” 

For the most part, the traffic patterns – and the coinciding traffic congestion – will not ease up until work is complete in one year. 

“We’ll lighten up with the end of tourist season, however,” Wyntergreen said.
