Corvallis is a city in Oregon. It is home to Oregon State University.
East towards I-5
Route 34 turns into two one-way roads as it crosses the Willamette River: Harrison Blvd heading west, and Van Buren heading east. Right before traffic enters the bridge is a fairly decent spot. There's also a traffic light about a block or two down.
When coming from the I-5, you can get out at Route 34, just south of Albany. Traffic entering 34 from I-5 South have a stoplight before they turn right onto 34 West. There's a decent shoulder where you can stand right at that stoplight and catch all the cars as they turn with a pull-out about 10m past the light.
