traveling over bridge

We have lived in Vancouver for many years. in that time traffic on I-5 and later 205 has increased to the point that getting to work in Portland not to mention getting home has become increasingly difficult. Areas in Vancouver are to be avoided when ever possible during high traffic time, most notably, include Mill Plain near 205 the orchards area on 117th. I would use bus or rail transport if it ran at more convenient times and frequency. Right now no one is going anywhere.
