Clatsop, Tillamook, and Columbia Counties State Highway Construction Update:
 
 
April 19-25
 
 
 
US101: Manzanita Ave. – Neahkahnie Creek 
(Oregon Coast Highway, mile post 43.00 to 43.34)
 
The work consists of replacement of an existing culvert at Neahkahnie Creek with a tunnel structure and enhancement of the stream bed as well as relocating and improving the highway alignment along U.S. 101 near Manzanita. Also, turning lane movements into downtown Manzanita will be enhanced. 
 
The scheduled work includes stabilizing the soil around the tunnel mining area. Flaggers may need to occasionally control single lane traffic during construction when work is occurring. Minor delays should be expected when single lane closures are occurring and the public is reminded to drive through the area with caution.  Oregon State Police will be enforcing the speed limit through the work zone area.  The project is scheduled to be completed in October 2016.
 
US101(Bus.): Old Youngs Bay & Lewis & Clark River Bridges    
(Warrenton - Astoria Highway, mile post 4.78 and 6.89)
 
This project consists of performing bridge rehabilitation work at both the Old Youngs Bay and Lewis & Clark River Bridges along US101(Bus.).
 
The scheduled work at the Lewis & Clark River Bridge includes coating the bridge steel underneath the bridge deck. Flaggers will control single lane traffic at the Lewis & Clark River Bridge during construction when work is occurring as required.  Minor delays should be expected when single lane closures are occurring and the public is reminded to drive through the area with caution.  Oregon State Police will be enforcing the speed limit through the work zone area. 
 
The scheduled work at the Old Youngs Bay Bridge includes rehabilitation of the electrical and mechanical systems along with the substructure of the bridge. In addition, coating of the bridge steel underneath the bride deck will be occurring. Flaggers will control single lane traffic at the Old Youngs Bay Bridge during construction when work is occurring as required. Minor delays should be expected when single lane closures are occurring and the public is reminded to drive through the area with caution. Oregon State Police will be enforcing the speed limit through the work zone area. Between April 11 and July 1, the Old Youngs Bay Bridge will be closed to all traffic, including bicycles and pedestrians, intermittently on approximately 25 different nights to allow for replacement of structural supports underneath the bridge. The closures will be from 6:00 PM until 6:00 AM.  Closures will not be occurring on Friday or Saturday nights.
 
The project is scheduled to be completed in November 2017.
 
 
US101: Columbia R (Astoria–Megler) Br Painting, Ph2 
 
(Oregon Coast Highway, mile post 2.78 to 3.26)
 
This project consists of recoating the steel below the bridge deck on the southern side of the Columbia River Bridge along U.S. 101 north of Astoria.
 
The scheduled work includes installation of the work containment structures and preparation and coating of the steel beneath the bridge deck. Flaggers will control single lane traffic during construction activities as required.  Lane delays will be allowed anytime on weekdays and weekends.  Expect delays of up to 20 minutes and drive through the area with caution.  Oregon State Police will be enforcing the speed limit through the work zone area.  The project is scheduled to be completed in September 2018.
 
 
 
U.S. 101/OR6 Traffic Improvement Project in Tillamook
This project improves traffic operations and performance, and increases safety on U.S. 101 and OR 6 through downtown Tillamook and across Hoquarton Slough.
 
The project will lengthen the U.S. 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. The project also improves the Hoquarton Interpretive Area, and adds gateway elements and downtown beautification.
 
Current work includes the demolition of buildings at the site of the new intersection of U.S. 101 and OR 6. This work marks the beginning of the first visible construction. Clearing the intersection site is not expected to create significant traffic or noise impacts. Demolition will take place entirely off road and trucks and machinery will not contribute significantly to existing traffic noise in the area. Flaggers will be in place to guide trucks and machinery into and out of the demolition area as required.
The project is expected to be completed in the fall of 2018.
