Over 50% of Oregon's curve warning and curve advisory speed signs do not meet current national standards. This is because of outdated technologies used in initial curve analysis, changes in driving habits, improvements in vehicle safety features and inconsistent curve advisory speed changes that have happened over the past several decades.
Upgrading and installing new signs will improve safety by having consistent curve advisory speeds and signs that meet the national standards.
Because many curves have posted advisory speeds that are lower than the current standards for safe driving, drivers often do not follow them. Instead, drivers travel five, ten, or more miles per hour over the posted advisory speed.
Travelers can expect lane closures and delays up to 20 minutes where work is taking place.
TripCheck.com will have the most up to date information on where work is being done and what the traffic impacts may be.
This project will be constructed in 2021.
The bridge was built in 1963 and with heavy traffic usage, deterioration and direct exposure to the elements, and rapid changes in temperature, the bridge is in need of repair.
The project will:
Most of the work that impacts the travel lanes will be done at night. There may be times when one lane closures occur to accommodate the equipment needed for the work and activities being done underneath the bridge.
A 14 day full night closure will occur in 2021 to replace the lift span bracing. During the night closures, traffic will detour onto the U.S. 101 Business route.
This project is expected to be completed in late 2021.
U.S. 101 – New Youngs Bay Bridge
This project is to replace the more than 50 year old bridge whose timber deck is in poor condition. As part of the project, we will also realign and widen the existing roadway and provide new striping and traffic signs. New bridge guardrails and other improvements will be made to the wayside.
The road realignment will improve visibility for local residents, road and river users using Farmer Creek Road and coming in and out of the wayside.
There will be lane restrictions and flagging for the duration of the project.
The wayside and boat launch will be CLOSED for stages during construction. Closure information and alternate boat launch information is posted at the wayside. During closures, river users will need to use alternate launches. To the north, use First Bridge Launch and to the south, you can use the Three Rivers Boat Ramp.
The most up to date traffic impacts and road closure information will be on TripCheck.com.
This project is expected to be completed in late 2020 or early 2021.
