After the issues have been identified, the Office of Transportation works with the public to develop potential alternative improvement scenarios to address them.  These alternatives are evaluated and screened using evaluation criteria developed with the public’s input.  Once they have been screened, a set of recommendations are developed to address the issue.     

These recommendations are generally grouped into two groups based on a number of factors including overall cost and expected impacts.  The projects with relatively low costs and few impacts are generally more short-term with an expected implementation time frame of 5-10 years.  The projects with a relatively high construction cost and more impacts are generally more long-term with an expected implementation time frame of 10+ years.
