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.

Highway 101/6 Project Update
February 23, 2017
Tillamook Area Chamber of Commerce

Now that all of the big girders for spanning the Hoquarton have arrived and are stacked alongside the roadway, the next gigantic arrival will be an enormous crane pulling into town this weekend to be on hand for setting the large pre-cast support caps during the negative tides Monday and Tuesday of next week.

The girders themselves are anticipated to be set the week following, along with the 800 pound bridge bearings that were just delivered to the site.  The bridge will begin to shape over the next month as all of these pieces are assembled.

Also in March, there will be fresh activity popping up at the far eastern end of the project around Goodspeed Park as foundations and trenching for electrical along the new bicycle/pedestrian trail gets underway.  This will be coupled with next week’s forming of the interior bays and overhang on the pedestrian walkway over the Port’s Highway 6 railroad bridge.

Highway 101/6 Project Update

Logs trucks move over; the bridge is arriving.

Starting tomorrow, Friday the 17th, and repeating next Monday & Wednesday, trucks bearing the long bridge beams will be coming to town.  Expect short delays as flag cars stop 101traffic while the trucks make the difficult turns into the work site to deliver the big sticks.

This is all gearing up so that Oregon State Bridge Construction can set the first span on March 7th.  Meanwhile the rest of the bridgework is continuing forward now that the Oregon Transportation Commission approved a Bridge Bent Cap redesign today.   This will replace the original cast-in-place components, poured inside a falsework cofferdam in the middle of the Hoquarton, with a pre-cast bent cap approach that forms up and pours the bridge supports off-site and trucks them in to avoid the trials and tribulations that this year’s heavy storm flows and high tides have brought to bear.
