Construction Impacts

​​Interactive Map IconConstruction crews began on February 8 to work on ADA curb ramps in south Corvallis. The project will be split into 2 phases. The first phase has started and will focus on constructing new ADA ramps at 17 different existing street corners and the second phase will complete the remaining 35 locations starting in July 2021.​

What to expect during construction:​
  • There will be noise and dust during work hours. 
  • Pedestrians, including those with disabilities, will have access through or around work zones.
  • Notice of upcoming pedestrian detours will be placed along sidewalks at least one week in advance.
  • When pedestrian detours are used across unmarked crosswalks, additional temporary crosswalk signing will be used wherever possible.
  • Watch out for signs about bicycles sharing the roadway through work zones.
  • Law enforcement will be patrolling the corridor during construction.
  • Only one corner of each intersection will be closed at a time. 
  • Work may occur at multiple intersections at the same time. 
  • Some work may require lane closures.
  • Work is expected to be done during the daytime from local streets and along OR 99W outside of peak traffic periods. 
  • Nighttime lane closures may be needed, especially north of Alexander Avenue, during certain times of the year.

​Pedestrians, including those with disabilities, will have access through or around work-zones.



Inspector on SidewalkWe are committed to providing the best accessibility possible to all people using the transportation system.  One of the ways we are doing this is by bringing curb ramps along our highways up to current ADA accessibility guidelines. We’re also exploring ways to design and construct these ramps more efficiently. 

This project will rebuild 52 street corners in Corvallis from SE Chapman Place to SW McKenzie Avenue. ​
