Vicinity Map Project Information Paper
Why is this project needed
Interstate 84 is a critical part of the State’s transportation system and is a major east-west corridor for the Western United States. Keeping the highways in good condition and providing a safe, efficient transportation system that supports economic opportunity are critical aspects of the mission for the Oregon Department of Transportation (ODOT).
The existing asphalt has reached its design life. The last time this section of highway was paved was in 1998. The existing roadway is showing signs of unraveling. The 2012 pavement rating for this section was fair. The existing concrete median barrier, which has been in place for decades, no longer meets the crash-worthiness requirements for the types and sizes of vehicles on our highways today.
How does ODOT propose to solve these problems?
ODOT plans to grind out the top 2” of pavement and replace it with 2” of dense, hot-mix asphalt concrete. Both the slow and fast lanes will receive the same treatment. Replacement of existing shoulder rumble strips is also included in the project, along with replacement of the substandard median barrier with new barrier that meets today’s requirements for crash worthiness.
Traffic control during construction
Paving of the slow lanes and outside shoulders will be performed at night while traffic is restricted to the fast lanes. Median paving and barrier replacement as well as paving of the fast lanes may be performed during daylight hours while traffic is shifted over into the slow lanes and shoulders. Only one travel lane will be closed in each direction at any given time during construction. Slowing of traffic is expected but there should not be delays.
