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.

May 24, 2017

Nighttime work to start on Pacific Avenue

TILLAMOOK— An additional southbound lane on U.S. 101 at the Hoquarton Bridge is scheduled to open earlier than expected on Wednesday, May 24 as part of the U.S. 101/OR 6 Project in Tillamook. A northbound lane is being shifted on to the new bridge restoring two lanes southbound. The plan was to have two lanes open in each direction by Memorial Day but that will not happen until later in the summer.

Also, starting on Tuesday, May 30 the contractor will be working at nights, Sunday to Thursday between 7 p.m. and 3 a.m. on Pacific Avenue. The night work is expected to be completed in early July at the latest.  Travelers can expect short delays during nighttime construction. 

After Memorial Day, the contractor will have two lanes open on Pacific Avenue during the day in Tillamook. Overall, the project is still on-schedule to be completed by the end of 2018.

Highway 101/6 Project Updates
May 23, 2017

Tonight’s the night that the switch gets flipped.  The asphalt crews will be working on the bridge from 7:00 PM until 2:00 AM at which time the night flaggers arrive so that the stripers can begin their work of grinding out the old striping and laying down the new travel lanes.  Come tomorrow morning, Wednesday the 24th, the new bridge will be accepting its first traffic. 

One lane of northbound traffic will be wiggled around the old Shell Station and guided up main to tie in over onto the new bridge come Wednesday morning.  For the duration of Wednesday, there will also be a single lane southbound on Main as the contractors complete the transition.  Once Thursday rolls around, traffic can return to two lanes southbound.
