Maximum word count for the URL

[Kwak]

Hi, I did some SEO on one of the site, which made the URL seem a bit lengthy due to the key-words conversion.

i.e. http://www.calpolyonline.com/forums/university-newsletters/announcements-community-adult-3095.html

Is this too long and could give the search engines (Google, Yahoo, and MSN) a second look at my site and possibility of putting a red flag?
A link would be helpful, thank you in advance.
