U.S. 101-The Oregon Coast Highway


ODOT’s Region 2 includes 198.58 miles of the Oregon Coast Highway, from south of Florence to the Oregon/Washington border, north of Astoria. 
US 101 is many things to many people.


  • It is a State and Federal Scenic Byway that offers unparalleled natural beauty and access to many cultural and historical sites. 
  • It is a lifeline to the residents who live along or near Oregon’s coast. 
  • It is a Main Street to the many cities through which it meanders.
  • It is home to the iconic and historic bridges designed by Conde McCullough .
  • It is an economic link between coastal communities and between coastal industries and inland markets.
  • It is a destination, in and of itself, for thousands of motorists and bicyclists.



ODOT's Challenge


For the Oregon Department of Transportation, US 101 represents a vulnerable ribbon of asphalt that must be maintained through the severe weather cycles of the coastal environment, and extreme geological forces including landslides and earthquakes.


On any given day, the Average Daily Trips—or the average number of vehicles traveling the highway –are: 
·        Astoria- 22,600
·        Seaside-15,900
·        Tillamook-17,100
·        Lincoln City-24,000
·        Newport-23,800
·        Florence-17,000
Understanding the economic importance of the highway, ODOT works hard to keep the highway in a safe and operable condition.
Between 2002 and 2015, ODOT will have delivered more than 190 projects, worth $800 million to coastal areas.  These projects include pavement preservation, bridge repair and replacement, emergency landslide repairs, culvert repairs and replacements, and other miscellaneous projects.  More than $350 million will have been spent on US 101 alone.
Despite the large expenditures, there is not enough funding to keep the coastal highways in optimal conditions.  There are simply more needs than we can keep up with, given the decline in annual budgets.  This funding reality forces us to make difficult decisions that try to balance many competing needs.

Current Issues 

Several issues related to US 101 are currently under discussion or review in media reports or various civic organizations.
Included in these issues is:
Flooding south of Seaside, where annual flooding during the heavy rains of winter often leaves the highway closed or restricted.  To learn about a multi-agency project to create a solution to the flooding, click here.  
The future of the Yaquina Bay Bridge has been under discussion and is the subject of a planning effort currently underway.  Visit the Yaquina Bay Bridge webpage to learn more.
Pavement conditions along US 101 in Lane County are a source of concern for bicyclists.  To learn why and what ODOT has planned, click here.
