While you're reviewing the draft Morgantown Bicycle Plan, you might take a look at Allegheny County's Active Allegheny plan:
http://www.activeallegheny.com/theplan.aspx . The Executive Summary and Chapter 2 are mostly relevant to bicycles. If you're at all familiar with Pgh, it's interesting to see how much they can do by just designating on-road bike routes and then where they plan bike lanes, shared-use paths, etc. Table 2-7 provides some unit cost info that we could use to estimate the cost of engineering initiatives in our plan.
